The document discusses different modes of reproduction in fungi including vegetative, asexual, and sexual reproduction. Vegetative reproduction occurs through fission, budding, fragmentation, or sclerotia formation. Asexual reproduction involves the formation of spores such as sporangiospores, oidia, chlamydospores, or conidia. Sexual reproduction involves plasmogamy, karyogamy, and meiosis, resulting in spores like ascospores or basidiospores. Fungi obtain nutrition through saprotrophic, parasitic, or symbiotic means.
Mycology is the branch of biology concerned with the study of fungi.
The word 'myco' is derived from the Greek word mýkēs meaning “mushroom, fungus”.
Heinrich Anton de Bary is the father of Mycology.
Fungi are eukaryotic organisms that include such as yeasts, moulds and mushrooms. These organisms are classified under kingdom fungi.
Fungi are diverse and widespread.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

3. INTRODUCTION
3
A fungus is a eukaryotic organisms that includes micro-organisms such as
yeasts and mold as well as the more familiar mushroom.
Fungus are heterotrophs, they acquire their food by absorbing dissolved
molecules typically by secreting digestive enzyme into their environment.
Reproduction: It is the process by which plant and animals give rise to
offsprings.
It maintain or ensure the continuity of the species, germination after
germination.
Reproduction in Fungi can occur by:
(i) Vegetative Reproduction
(ii) Asexual Reproduction
(iii)Sexual Reroduction
4. VEGETATIVE REPRODUCTION IN FUNGI
4
Vegetative reproduction is any form of reproduction occurring in plants in which a new plant
grows from a fragment of the parent plant or a specialized reproductive structure, the following
method are-Fission,Budding,Fragmentation,Sclerotia.
Fission: Some single-celled fungi, reproduce by
simple cell division, or fission, in which one cell
undergoes nuclear division and splits into
two daughter cells.
Some yeasts multiply by fission or division of
parent cell into equal halves and each half forms a
new individuals.
Pr0cess of Fission: In binary fission a mature
cell elongates and its nucleus divides into two
nuclei.
• The daughter nuclei separates, cleaves cytoplasm
centripetally in the middle till it divides parent into
two daughter protoplasm.
• A double cross wall is deposited in the middle to
form two daughtercell.
• Examples: Saccharomyces , Psygosaccharomyces
5. Budding: It is another method of vegetative reproduction, occurs in most yeasts
and in some filamentous fungi. In this process, a bud develops on the surface of either
the yeast cell or the hypha, with the cytoplasm of the bud being continuous with that
of the parent cell.
Often the buds are produced in a chain called as Promycelium.
Process of budding:
• Thecell wall bulgeout and softens in thearea probably by certain enzymes brought by
vesicles.
• The protoplasm also bulgeout in this region as small protuberance.
• The parent nucleus also divides into two, one of the daughter nucleus migrates into
bud, the cytoplasm of bud and mother remain continuous for some time
• As the bud enlarges, a septum is laid down at the joining of bud with mother cell.
Then bud separates and leads independent life.
• Some time, bud starts reproducing while still attached with mother cell. This gives
branching appearance.
• Budding is the typical reproductivecharacteristics of Ascomycetes.
• Examples: Yeast
5
6. Fragmentation:
It occur in mycelial fungi .If the thallus is
broken up into smaller fragment either by
accidently or through use of external
forces,each small mycelial fragment grown
into a new individuals.
In the laboratory,
commonly propagated on a
fungi are
layer of solid
nutrient agar inoculated either with spores or
with fragmentsof mycelium.
Examples: Mushrooms.
Sclerotia:
The sclerotia are resistant and penetrating bodies.
Each sclerotium is cushion-like structure of compact
mycelium. They give rise to new mycelia on the
approach of favourableconditions.
Fragmentation
Sclerotia
7. ASEXUAL REPRODUCTION IN FUNGI
7
Asexual reproduction occurred by formation of spores, A spore is a small
specialized uni and multicellular reproductive unit of dispersal that grows
into a new individuals like the parent after liberation. The following spores
are-
Sporangiospore , Oidia, Chalamydospores, Conidia
The spores are of diverse type and borne upon special structures called the
sporophores. These spores are produced asexually and called the asexual
spores.
Usually the spores are uninucleate and nonmotile but multinucleate and
motile spores are also
found.
The fungus producing more than one type of spores is called the pleomorphic
orpolymorphic.
The spores produced inside the sporangia are termed the endogenous spores
and the spores developing exogenously on the terminal ends of sporophores
arecalled theexogenous spores.
8. Some Examples of Asexual Spores
Sporangiospore: Theseasexual spore are produced in a sac like structure called
sporangia.
• Sporangium are produced at theend of special aerial hyphae called sporangiophore.
• Sporangium contains large numbers of haploid spores, which are released by rapture
of sporangial wall. Examples: Rhizopus
Oidia: These are the spore like hyphal segments in several fungi hypha divides by
transverse wall into a numbers of component cells or Oidium.
Chlamydospore: These are usually formed during unfavorable condition and are
thick walled singlecelled spore, which are highlyresistant to adversecondition.
• Hyphal cell or portion of hyphae contracts, loose water, round up and develops into
thick walled chalmydospore.
• When favorable condition returns, each chlamydospore give rise to a new
individual fungi. Examples: ascomycetes, basidiomycetes, zygomycetes, Histoplasma
capsulatum.
Conidia: The conidia are produced exogenously. They are non –motile spores extruded
singly or in chains from the tips of special hyphal branches called Conidiophores or
Conidia. Example: Penicillium, Apergillus
8
10. Sexual Reproduction: It involves the formation and fusion of
gametes. Sexual reproduction found in all groups of fungi
except deuteromycetes or fungi imperfecti. Sexual
reproduction has three distinct phases i.e.
1. Plasmogamy (protoplasmic fusion): The process is the fusion
between two protoplasts of either gametes or cells to be
together the haploid nuclei of opposite mating type for their
ultimate union.
2. Karyogamy (fusion of nuclei): It is the fusion of two
compatible nuclei into one diploid nucleus.
3. Meiosis : Reduction division of zygote.
SEXUAL REPRODUCTION IN FUNGI
10
11. Some Examples of Sexual Spores
Ascospore:
• It is usually singlecelled produced in a saccalled ascus (plural;asci) and usually thereare 4-8
ascospore in an ascus but the number mayvary from species tospecies
• The ascospore are usually arranged in a linearorder. In somecase ascospores are long, narrow
and arearranged in parallel order.
Basidiospore:
• It is a reproductive spore produced by basidiomycetes.
• This singlecelled spores are born in aclub shaped structure called basidium
• These basidiospore aervesas main airdispersal unit for the fungi.
Zygospore:
• Zygospores are thick walled spores formed when two sexuallycompatible hyphae orgametangia
of certain fungi fuse together.
• In suitablecondition, zygosporegerminates to produce a singlevertical hyphae which forms a
aporangium and releases its spores
Oospore:
• Theseare formed within a special female structure called Oogonium.
• Fertilization of egg by malegamete in female sex organ giverise tooospoes.
• Thereareone or moreoospores in each oogonium.

13. NUTRITION
13
Fungi obtain their food by absorbing organic compounds
from their surroundings. Basis of their nutrition, they are
clasified as:
Saprotrophic Fungi: Fungi obtain food from dead and
decayed materials. Example: Aspergillus.
Parasitic Fungi: Get feed from living Organisms and
destroy them. Example: Puccinia.
Symbiotic Fungi: Grow in a living Organism and get
mutually benefited. Example: Lichen.
14. CONCLUSION
14
The majority of Fungi are capable of both asexual
and sexual reproduction, which enable them to adapt
into the changing environmental circumstances.
Fungi have the ability to transform nutrients in a way
that makes them available for plants. Some fungi are
decomposers which mean that they break down
plant and animal debris, thus cycling nutrient and
increasing their availability in the soil.
