AP Biology Ch. 16 Embryonic Development and Cloning
The document discusses the genetic basis of development from a single-celled zygote to a complex multicellular organism. It describes three key processes - cell division, cell differentiation, and morphogenesis - that overlap during embryonic development. A series of classic experiments provided evidence for the concept of genomic equivalence, showing that differentiated cells contain all the genetic information to generate a new individual. Stem cells offer potential medical applications but also raise ethical issues.
Developmental Biology
1. The document discusses gradient theory and nuclear transplantation. Gradient theory proposes that embryonic development is controlled by gradients of factors from the animal to vegetal pole. Nuclear transplantation involves removing the nucleus from a donor cell and transplanting it into an enucleated egg.
2. The document describes two types of gradient theories - the single gradient theory involving one factor and the double gradient theory involving antagonistic animal and vegetal gradients. It provides examples of experiments supporting these theories.
3. Nuclear transplantation techniques are explained, including types of transplantation. Experiments transplanting nuclei between frog species resulted in normal development, showing the totipotency of early nuclei.
Developmental biology course presentation
This document provides information on an international course on developmental biology to be held in Paris in October 2011. The course will be held at Pierre and Marie Curie University and the Curie Institute. It is intended for master's and PhD students and will include 3 weeks of practical laboratory sessions and 2 weeks of lectures. The practical sessions will cover topics like early mouse development, chick embryo culture, Drosophila imaginal discs, Xenopus embryos, C. elegans, and zebrafish. The lecture sessions will feature talks from researchers on various topics within developmental biology.
Basics of developmental biology 1
This document provides an overview of key concepts in developmental biology. It discusses induction, in which one cell or tissue signals another to influence developmental fate. Competence is the ability of a cell to respond to inductive signals through expression of receptors. Commitment is when a cell decides its fate, either through inductive signals or cytoplasmic determinants distributing asymmetrically. Specification is a reversible commitment, while determination is irreversible. Differentiation allows cells to become specialized through protein synthesis. Morphogenesis involves a cell gaining a particular shape. Autonomous and conditional specification are strategies where cells determine fate independently or through interactions, respectively.
Evolutionary developmental biology
Evolutionary developmental biology examines the development of different organisms to understand ancestral relationships and how developmental mechanisms lead to evolutionary changes. It focuses on genes that control development and how changes in these genes can produce variation that is acted on by natural selection. A key example is that morphological differences between chicken and duck feet are due to different expression of BMP4 and Gremlin genes, which control cell survival and apoptosis in the developing limb. Developmental genes like Hox genes are important for pattern formation and have been pivotal in animal evolution by allowing variation and the formation of new body plans.
Developmental biology
Developmental biologists are asking questions about how genetic information results in different cell types, how cell division and formation of organized structures are regulated, and how reproductive cells are set apart. They study development through comparative embryology, evolutionary embryology, teratology, and mathematical modeling. Some key concepts are epigenesis versus preformation, germ layers and induction, von Baer's principles of vertebrate development, fate maps, distinguishing analogous and homologous structures, and types of growth models.
Introduction of development biology
Developmental biology is the study of the processes by which organisms grow and develop. It expanded on classical embryology by using modern molecular techniques and genetic approaches. Some key areas of study include differentiation, morphogenesis, growth, reproduction, evolution, and environmental influences. Early debates centered around whether embryonic structures were preformed in the egg (preformationism) or arose de novo through epigenesis. Landmark studies in the 1800s by scientists like Pander, von Baer, and Rathke established germ layer formation and embryonic development principles. Lineage tracing techniques using dyes were later developed to track cell lineages in living embryos of organisms like tunicates, amphibians, zebrafish, and frogs.
Environmental regulation of animal development
1. The environment regulates animal development in several ways, such as requiring certain substrates to trigger metamorphosis or relying on symbiotic bacteria for proper organ development.
2. Environmental conditions can influence development through phenotypic plasticity, inducing different phenotypes from the same genotype. Some species exhibit polyphenisms where the environment determines distinctly different phenotypes.
3. Factors like seasonality, temperature, food availability, and presence of predators can alter development to increase fitness. Temperature also determines sex in some species.

3. Factors like seasonality, temperature, food availability, and presence of predators can alter development to increase fitness. Temperature also determines sex in some species.
Basic concepts in developmental biology
Cell differentiation allows for the formation of distinct cell types through differential gene expression. A cell's fate and potency become progressively restricted through developmental commitments in response to cytoplasmic determinants or inductive signals from other cells. Pattern formation organizes cells in the embryo according to their position through mechanisms like morphogen gradients, which establish regional identities and compartments that segment the body plan.
Embryogenesis
Arabidopsis is a model organism for studying embryogenesis. During embryogenesis, an asymmetric first cell division establishes the apical-basal axis. Subsequent cell divisions generate distinct domains that give rise to different embryonic structures. Key processes in embryogenesis include establishment of stem cell populations, formation of the shoot and root apical meristems, and development of organs like cotyledons and hypocotyl. Many genes regulate patterning events during embryogenesis through mechanisms like hormone signaling and transcription factor movement. Mutations in these genes can disrupt normal embryo development.
Embryogenesis
Embryogenesis is the process by which a plant embryo develops from a fertilized ovule. It involves asymmetric cell division and differentiation of unspecialized cells into tissues and organs. There are two types of embryos: zygotic embryos formed from the zygote, and non-zygotic embryos like somatic and parthenogenic embryos formed from non-zygote cells. Somatic embryogenesis is the process where somatic cells develop into embryos and can regenerate whole plants. It occurs through direct or indirect routes. Key stages of somatic embryogenesis include globular, heart, torpedo and mature stages. Growth regulators like auxins and cytokinins play an important role in somatic embryogenesis.
Developmental biology
Sexual reproduction involves combining the chromosomes of two parents so that no two offspring are identical. Most organisms reproduce sexually. The evolution of sex is puzzling given its costs, but it provides genetic variation that helps populations adapt to changing environments, as proposed by the Red Queen Hypothesis. Meiosis during gamete formation and fertilization contributes to this genetic variation between offspring.
Germ line determination (2)
1. Primordial germ cells (PGCs) give rise to gametes through a two-step process - PGCs are first determined in a specific embryonic location, then migrate to the gonads.
2. PGC determination occurs either autonomously via cytoplasmic determinants ("germ plasm") or conditionally through signals from surrounding cells. In mammals it is conditional.
3. In many animals like nematodes and frogs, germ plasm localized in the early embryo autonomously specifies PGCs, which then migrate to develop into eggs and sperm in the gonads.
PATTERN FORMATION
This document outlines a course on developmental biology and teratology. It discusses how pattern formation during embryogenesis is genetically controlled and involves cells responding to morphogen gradients and cell signaling pathways to develop spatial patterns. Key genes involved in pattern formation are homeobox genes, which help specify where anatomical structures will develop. In particular, Hox genes are organized in clusters and control patterning along the anteroposterior body axis. Mutations in genes of pattern formation can lead to various clinical congenital malformations and anomalies.
Cell fate (fate maps)
Fate maps are the bases for experimental embryology since they provide researchers with information on which portions of the embryo normally become which larval or adult structures.
pattern formation genes
This document discusses pattern formation during embryogenesis. It begins by defining pattern formation as the development of spatial organization that establishes an organism's basic body plan and axes. Key genes that control pattern formation are homeotic genes, which regulate cell processes and contain a homeobox sequence. Hox genes pattern the anteroposterior axis by being expressed sequentially. In Drosophila melanogaster, cytoplasmic determinants, segmentation genes like gap and pair-rule genes, and homeotic genes work together to pattern each segment. Mutations in these pattern formation genes can lead to congenital malformations in humans and other organisms.
History of embryology
This document provides an overview of the history and techniques of embryology. It discusses how embryology has advanced from early observations to the use of microscopes and experimental techniques. Key developments included the cell theory, theories of preformation and epigenesis, and von Baer's laws of development. Modern techniques allow for prenatal screening and diagnosis using ultrasound, maternal serum screening, amniocentesis, and chorionic villus sampling. Fetal therapy is also possible through transfusions, medications, and even surgery. The field also studies concepts like stem cell potency, differentiation, and regeneration. A variety of methods are used like histology, tracing, transplantation, and culture techniques.

Cell proliferation & differentiation
1. Embryonic development involves cell proliferation to increase cell numbers through cleavage and cell differentiation to form different cell types through determination.
2. Gene expression, cell communication, hormones, and environmental factors control this process by regulating proliferation and differentiation.
3. Early embryonic development progresses from a single zygote to a complex organism through regulated cell proliferation, differentiation, and morphogenesis.
Developmental biology
This document describes the key stages of human embryonic and fetal development. It begins with an introduction to embryology and the processes of gametogenesis that produce egg and sperm cells. There are then four main sections that outline the major developmental periods: 1) Germinal stage, which involves fertilization, cleavage of the zygote, and blastulation. 2) Gastrulation stage, where the embryo reorganizes into three germ layers. 3) Neurulation stage where the neural tube forms from ectoderm. 4) Organogenesis stage in which organs begin to form and differentiate. The document then describes fetal development in the second and third trimesters, focusing on continued growth and differentiation of organ systems.
Animal development
Fertilization involves the combining of haploid sets of chromosomes from two individuals into a zygote. This is followed by cleavage, where rapid cell division occurs. Then gastrulation takes place, where cells migrate to locations that will form organs and tissues. Finally, organogenesis occurs, where organ rudiments develop from the three germ layers.
Developmental Biology of Drosophila
The document discusses development in Drosophila melanogaster (fruit flies). It describes how maternal molecules establish body axes in the early embryo before cell differentiation. Segmentation genes are then expressed in gradients controlled by these maternal factors and establish the basic body plan. These include gap, pair-rule and segment polarity genes. Finally, homeotic genes specify the identity of each body segment and control structure formation. This cascade of gene regulation results in the distinct segments that make up the adult fly body.
Reproduction Notes
The document summarizes key concepts about cell reproduction, mitosis, meiosis, and human reproductive systems. It discusses how all cells come from preexisting cells and undergo cell division. Mitosis and meiosis are described as processes that allow for cell growth and reproduction. Meiosis results in gamete formation with half the normal number of chromosomes. The male and female reproductive systems are compared, outlining gamete production and hormonal regulation of the process.
Embryogenesis deepika
1) The document discusses various types of embryogenesis including the Onagrad, Asterad, Solanad, Chenopodiad, and Caryophyllad types.
2) It provides examples of plant families that exhibit each type and describes how the apical and basal cells divide and contribute to embryo formation.
3) General patterns of embryo development are described for dicots using Ceratocephalus falcatus as an example, and for monocots using Najas lacerata.
FATE Map
A chart showing the fate of each part of an early embryo, in a particular blastula stage is called fate maps. It is done because the correct interpretation of gastrulation is impossible without the knowledge of the position which are the presumptive germinal layers (Ectoderm, Mesoderm and Endoderm) occupy in blastula.
Fate mapping is a method used in developmental biology to study the embryonic origin of various adult tissues and structures. The "fate" of each cell or group of cells is mapped onto the embryo, showing which parts of the embryo will develop into which tissue. When carried out at single-cell resolution, this process is called cell lineage tracing. It is also used to trace the development of tumors.
Genetic control of animal development
- Animal development is defined as the progressive changes in size, shape, and function that occur during an organism's life through which its genetic potential is translated into mature systems.
- Maternal genes play a major role in early development by providing nutritive and determinative materials to the egg during oogenesis, organizing the egg for subsequent development. Mutations in these maternal effect genes can impact offspring viability without affecting the mother.
- After fertilization, zygotic gene expression begins from the embryo genome, directing cell differentiation and organ formation under genetic control. Homeotic genes determine body segmentation by transforming one segment into another.
P S H S U P C A T Review Bio ( Part 1)
The document discusses various biology topics including cell organelles, osmosis, photosynthesis, respiration, the immune system, reproduction and development in animals, evolution, and ecology. It provides information on the structures and functions of organelles like the mitochondria and nucleus. It explains concepts such as osmosis, diffusion, active transport and homeostasis. Key processes like cellular respiration and photosynthesis are defined. Immune system cells and their roles are outlined. Stages of animal development from fertilization to gastrulation are named. Principles of evolution, reproduction and ecology are touched on.
Developmental Specification & Differentiation
1) Cell differentiation occurs after cell commitment, which involves two stages - specification and determination. Specification makes a cell's fate reversible, while determination makes it irreversible.
2) There are three types of specification - autonomous, conditional, and syncytial. Autonomous specification relies on cytoplasmic determinants, conditional specification relies on cell interactions, while syncytial specification involves cytoplasmic bridges between cells.
3) Early experiments by Weismann and Roux supported autonomous specification, but Hans Driesch's isolation and recombination experiments on sea urchin embryos provided evidence of conditional specification, where a cell's fate depends on its neighbors.
Assessment of Learning 2
This document discusses different grading systems used at various educational levels. It provides examples of reporting student achievement using percentages, numbers, letter grades, and descriptions. For basic education in the Philippines, the document outlines the features of the new grading system established by the Department of Education, including setting the minimum passing grade at 75% and lowest failing grade at 65%. Student assessments consist of different weighting for basic, moderately difficult, and higher-order thinking skills questions. Grades are calculated based on raw test scores averaged across quarters by subject.
Introduction to developmental biology
This document provides an introduction to developmental biology, including:
- A brief overview of the history of the field from descriptive embryology to experimental and analytical embryology pioneered by Morgan.
- Key historical figures and their contributions, like Aristotle's early work in embryology, preformation theories proposed by Swammerdam and Hartsoeker, and the epigenetic theory of Wolf and Haeckel.
- Important theories and principles like Baer's law of development, the recapitulation theory of Muller and Haeckel, Weismann's germplasm theory, the mosaic and regulative theories of development by Roux and Driesch, and Spemann's theory of organizers.

Context


As a branch of psychology, contemporary biopsychology studies the relationships between behavior and (mainly) the brain. Before this central hypothesis was established, the popular mind-brain questions raised in history included "What is the mind?" and "Does the mind control the brain or vice-versa?" Numerous scientists, psychologists, philosophers, and other scholars answered these questions differently and developed a variety of theories to explain their rationale.

Action Potential


The brain is part of the nervous system. A particularly important aspect of the nervous system is how neurons "fire," or act to transmit information. This process is known as the action potential and is governed by several different factors, including neurotransmitters and electrolytes.


Action potentials are subject to several laws. For instance, according to the all-or-none principle, an action potential occurs at full strength or not at all. This theory has been a foundation of the studies


of the brain and the theory is widely applied in today's medicine as well as the computer world and the robot industry.
Nature or Nurture?
The relationship between heredity and the environmental influence in shaping behavior has long been the topic of studies. The history of biological psychology development includes the contributions of Descartes, Fritsch, and Hitzig, Helmholtz, Broca, Gall, and Lashley. One of the most exciting scientific discoveries in the twentieth centu.

Plenary Talk “The banana pangenome, evolution, and exploiting biodiversity“ Pat Heslop-Harrison phh@molcyt.com for Malaysian National Banana Congress 2021
Banana production faces challenges from biotic (disease) and abiotic (environment) stresses.
New genetic characteristics are needed for stress resistance and to improve yield, agronomy, post-harvest quality, nutritional value, and even for new food or industrial uses.
Improvement requires i) identification of the challenge; ii) identification of useful genetic variants; iii) potentially bringing together useful variants in a single plant; iv) testing of characteristics of a new variety; and v) propagation and planting.
I will discuss our results measuring diversity in germplasm from banana and its sister species including the starchy Ensete, towards generating a pan-genome representing the entire genetic diversity within the Musaceae family.
I will consider how this diversity has evolved and how we might use it as a common gene pool to improve banana for the benefit of smallholder or commercial farmers, and for the sustainability in the environment.

phh(a)molcyt.com
Within the Zingiberales there are many orphan crops that are grown in Africa and Asia where recently started genomic efforts will have an impact for the future understanding and breeding of these crops. Advanced genomics and genome knowledge of the taxonomically closely related genus Musa will help identify genes and their function. We will discuss relevant recent work with Musa and results from DNA sequencing, examinations of diversity and studies of genome structure, gene expression and epigenetic control in Boesenbergia and ensete. Ensete is an important starch staple food in Ethiopia. It is harvested just as the monocarpic plant starts to flower, a few years after planting, and the stored starch extracted from the pseudo-stem and corm. A genome sequence has been published, but there is little genomics. Characterization of the diversity in the species and understanding of the differences to Musa will enable selection and breeding for crop improvement to meet the requirements of increasing populations, climate change and environmental sustainability. Boesenbergia rotunda is widely used in traditional medicine in Asia and has been shown to produce secondary metabolites with antiviral activity. For high throughput propagation and metabolite production in vitro culture is employed; embryogenic calli of B. rotunda in vitro are able to regenerate into plants but lose this ability after prolonged periods in cell suspension media. Epigenetic factors, including histone modifications and DNA methylation are likely to play crucial roles in the regulation of genes involved in totipotency and plant regeneration. These findings are also relevant to other crops within the Zingiberales. Further details will be given at www.molcyt.com
Domestication, polyploidy and genomics of crops #PAGXXV Heslop-Harrison
This document discusses domestication, polyploidy, and genomics of crops and weeds. It notes that most major crop species were domesticated around 10,000 years ago, with a few more recently. Polyploidy, or whole genome duplication events, have also played an important role in crop evolution. The document examines genome sizes and components of various crop species, and notes that repetitive elements like transposons can make up large proportions of plant genomes. Differences in repetitive sequences between microspecies of dandelion are also discussed.

Molecular cytogenetic analysis of the chromosomes of oil palm allows us to understand their evolution, genetics and segregation, genetic recombination and karyotypic stability. The cytogenetic manipulation of genomes and their chromosomes is often valuable for plant breeders to introduce and exploit new variation. Cytological landmarks such as centromeres, telomeres, heterochromatin and nucleolar organizer regions are important for the integration of physical chromosomes with the DNA sequence information. This linkage of the genetic, chromosomal and physical maps is particularly useful in a long-lived tree crop where genetic mapping requires decades of preparation and the mapping crosses may not be directly relevant to DxP commercial plantings. Repetitive DNA is often the most rapidly evolving genomic component, but is poorly understood from sequence assemblies; molecular cytogenetic studies allow its organization and variation to be studied, and the exploitation of repetitive sequences as markers and, by the amplification and mobility of transposable elements or satellite repeats, in generation of new variation.
Molecular cytogenetic approaches provide tools for oil palm genomic research, comparative genomics and evolutionary studies and further facilitate understanding the inheritance of specific traits in oil palm, including DNA methylation, epigenetics, and somaclonal variation, allowing work with hybrids, haploids and polyploids. Knowledge of the structures and organization of the chromosomes of oil palm, as in many crop species, is valuable for development of new lines, making hybrids, understanding the causes of some abnormalities or infertility, and exploiting variation and biodiversity found in related species or breeding lines.

Gregor Mendel conducted experiments in the 1860s crossing different varieties of peas to study inheritance of traits. He observed that traits were passed down to offspring in predictable patterns, either dominantly or recessively. This work established foundations of genetics but was not widely recognized until the early 1900s. At the time of Mendel's work, cell structures like chromosomes were just beginning to be described microscopically, and their functions in heredity were not understood. Since Mendel, chromosome behavior during cell division has been shown to explain his laws of inheritance, and molecular genetics has revealed chromosomes contain genes on DNA that determine traits.Banana Transposable Elements: The hAT DNA element story PAGXXIII

Like other plant species, DNA transposable elements and retrotransposons represent a large fraction of the Musa genome. Mobile elements can be identified 1) by homology to known elements; 2) by characteristic sequence properties such are repeats and short duplications; and 3) by studying their mobility and insertions/deletions in comparisons of homologous or homoeologous chromosome sequences. We have used all three approaches in Musa and I will show results showing the nature of unselected mobile sequences in Musa accessions. Many of the active elements proved to belong to the hAT family of DNA transposons, where there has been limited information on their diversity, abundance and chromosomal localization in plants. Chromosomal in situ hybridization, in silico analysis of genomic sequences, Southern hybridization and biodiversity panels were used to show three major families of the elements in Musa, with some 70 complete autonomous elements, and abundant hAT-related MITEs (Miniature inverted tandem elements).MuhAT transposons and MuhMITEs were localized in subtelomeric, most likely gene-rich regions, of chromosomes. Variation between homologous chromosomes and transduplications of genomic sequences indicate activity of the transposons and suggest a role for the MITEs in modulation of genomic behaviour.

This document describes the use of total genomic DNA as a probe for in situ hybridization to identify the parental origin of chromatin in hybrids and determine if they are auto- or allo-polyploids. It can also be used to identify alien chromatin introgressed in breeding lines by determining its size and origin chromosome. The technique has been applied to many plant species to help understand hybrid genomes by examining chromosome behavior and chromatin function during meiosis and interphase.

Tandemly repeated satellite DNA in the Artiodactyla - a lecture
Tandemly repeated, satellite, DNA sequences are an abundant component of the genome of most species, including the Artiodactyla. Multiple DNA familes are present, each in long tandem arrays, with members of each family present on one or more chromosomes at characteristic positions. In particular, several familes are located at the centromeres of most chromosomes, including acrocentrics, metacentrics and the sex chromosomes. Individual arrays are made up of variants of particular sequence motifs, which may be longer than 1,500 bp. In this presentation, we will discuss aspects of the evolution of repetitive sequences within and between chromosomes, with comparative data between different species. With pig, we will show details of the localization of tandem repeats at meiosis, and how these sequences relate to sequence amplification and loss, as well as the epigenetic behaviour of the resulting heterochromatin. In the Bovinae, we will show how molecular cytogenetic methods are essential to build up a full picture of the behaviour and distribution of satellite DNA where current sequencing methods are unable to assemble the sequences blocks accurately.
