We will learn
General characteristics of fungi
Structure of fungi
Economic Importance

Brief intro of some fungi
THE SIX KINGDOMS
Fungi are placed in a separate kingdom called the kingdom fungi
OF FUNGI
CHARACTERISTICS
The Characteristics of Fungi
Fungi are NOT plants
Nonphotosynthetic
Eukaryotes
Nonmotile
Most are saprobes (live on dead organisms)
The Characteristics of Fungi
Absorptive heterotrophs (digest food first & then absorb it into their bodies
Release digestive enzymes to break down organic material or their host
Store food energy as glycogen
The Characteristics of Fungi
Important decomposers & recyclers of nutrients in the environment
Most are multicellular, except unicellular yeast
Lack true roots, stems or leaves
fungi as a decomposers
The Characteristics of Fungi
Cell walls are made of chitin (complex polysaccharide)
Body is called the Thallus
Grow as microscopic tubes or filaments called hyphae
The Characteristics of Fungi
Some fungi are internal or external parasites
A few fungi act like predators & capture prey like roundworms
The Characteristics of Fungi
Some are edible, while others are poisonous
The Characteristics of Fungi
Produce both sexual and asexual spores
Classified by their sexual reproductive structures
The Characteristics of Fungi
Grow best in warm, moist environments
Mycology is the study of fungi
Mycologists study fungi
A fungicide is a chemical used to kill fungi
The Characteristics of Fungi
Fungi include puffballs, yeasts, mushrooms, toadstools, rusts, smuts, ringworm, and molds
The antibiotic penicillin is made by the Penicillium mold
FUNGI SIZE
NON-REPRODUCTIVE
Vegetative Structures
Hyphae
Tubular shape
ONE continuous cell
Filled with cytoplasm & nuclei
Multinucleate
Hard cell wall of chitin also in insect exoskeletons
Hyphae
Stolons – horizontal hyphae that connect groups of hyphae to each other
Rhizoids – rootlike parts of hyphae that anchor the fungus
Hyphae
Cross-walls called SEPTA may form compartments
Septa have pores for movement of cytoplasm
Form network called mycelia that run through the thallus (body)
Absorptive Heterotroph
Fungi get carbon from organic sources
Tips of Hyphae release enzymes
Enzymatic breakdown of substrate
Products diffuse back into hyphae
Modifications of hyphae
Fungi may be classified based on cell division (with or without cytokinesis)
Aseptate or coenocytic (without septa)
Septate (with septa)
Modifications of hyphae
Hyphal growth
Hyphae grow from their tips
Mycelium is an extensive, feeding web of hyphae
Mycelia are the ecologically active bodies of fungi
ASEXUAL & SEXUAL SPORES
REPRODUCTIVE STRUCTURES
REPRODUCTION
Most fungi reproduce Asexually and Sexually by spores
ASEXUAL reproduction is most common method & produces genetically identical organisms
Fungi reproduce SEXUALLY when conditions are poor & nutrients
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species.The defining feature of this fungal group is the "ascus" (from Ancient Greek ἀσκός (askós) 'sac, wineskin'), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as Cladonia belong to the Ascomycota.
Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes are now identified and classified based on morphological or physiological similarities to ascus-bearing taxa, and by phylogenetic analyses of DNA sequences.
Describe in detail about fungi and general characters of fungi and different modifications and reproduction in fungi especially for undergraduate students
Detail description about important fungi that comes under chytridiomycota and zygomycota has been described, gives an idea about fungi and their life cycles under thus groups

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

2. MYXOMYCETES: WHY STUDY THEM
HERE?
• Members of this division are commonly
referred to as slime molds.
• Classified as Pro8sts: since they form
amoeboid cells
• Regarded as Fungi: because they produce
spores that are borne in sporangia
4. PLASMODIUM
• A naked mul8nucleate
mass of protoplasm
that moves and feeds in
an amoeboid fashion
• Formed aDer numerous
mito8c division of the
zygote
5. MYXAMOEBA
• An amoeboid cell released by the
spore upon germina8on
• May con8nue to proliferate for an
indefinite period of 8me if there is
available nutrient and the
environment remains favorable
• 2 func8ons: ingest food or func8on
as gametes during during
reproduc8on
6. SWARM CELLS
• When free water is
available, myxamoebae can
become flagellated and
swim through the water
• During condi8ons
unfavorable for
myxamoebae growth, the
cells may round up and
form the resistant microcyst
stage
7. SCLEROTIA
• A hard res8ng body resistant
to unfavorable condi8ons
• When condi8ons become
unfavorable, a plasmodium
can become dormant forming
a resistant stages
• Actually composed of smaller
units called macrocysts
9. FRUTING BODIES
• Frui8ng bodies may
either be carrying
spores externally or
internally
• Exospores: Example
Cera%omyxa
– Columnar, branched
structures bears the
spores externally
10. FRUITING STRUCTURE TYPE 1:
PLASMODIOCARP
• An elongated, curved or
branched, vein‐like frui8ng
structure
• Example: Hemitrichia
serpula
– The spores and capilli8um of
this sporangium type retains
the shape of the plasmodial
stage
11. FRUTING STRUCTURE TYPE 2:
SPORANGIUM
• Sac‐like structure
• Example: Physarum and Dydmium
• the fragile, outer layer of the
sporangium is the peridium which
may be persistent or degenerate
by the 8me the sporangium is
ready to disperse its spores
13. FRUITING STRUCTURE TYPE 3:
AETHALIUM
• aethalium resembles a
sessile sporangium but is
much larger and generally
cushioned
– Believed to be fused
sporangium
• Example:
– Lycogala = pseudocapilli8um
without any dis8nc8ve
ornamenta8on and spores
– Fuligo = produces the largest
known aethalium
14. VARIATIONS IN CAPILLITIUM
MORPHOLOGY
Example: Trichia favoginea, capilli8um ornamented
with annular rings
Example: Hemitrichia serpula, capilli8um
unbranched. Composed of strands of elaters. Elaters
ornamented with double spirals, each coming from
opposite direc8ons
Example: Lycogala epidendrum, Capilli8um (actually
pseudocapilli8um) without any dis8nc8ve
ornamenta8on and spores
15. ACRASIN
• Chemotac8c chemicals that act as
pheromones in aggrega8on of amoebae in
cellular slime molds
• One of the earliest iden8fied acrasins: cyclic
AMP or cAMP
– Dictyostelium discoideum
– exhibits a complex swirling‐pulsa8ng spiral paUern
when forming a pseudoplasmodium
17. IMPORTANT TERMS
• ZYGOSPORE
– A res8ng spore that
results from the fusion
of 2 gametangia
• ZYGOSPORANGIUM
– A sporangium containing
a zygospore
• ZYGOPHORE
– A special hypha capable
of developing into a
progametangium
18. DIMORPHIC GROWTH
• Producing two
morphologically‐dis8nct
types of zoospores (yeast
form or mycelial form)
• Usually the yeast type occurs
internally and the mycelial
type occurs externally (with
excep8ons)
23. SPORE DISPERSAL
• Ini8al result to phototrophic response of the
sporangiophore and later its elonga8on
• Steps:
– Sporangiophore bends towards the light
(sporangial vesicle act as lens)
– Subsporangial vesicle has high turgor pressure,
upon rupture will eject the sporangium towards
the source of light
25. DIFFERENCES BETWEEN ORDERS
• ORDER MUCORALES
– They have a well developed mycelia that is generally aseptate.
Whenever septa will be present, they lack spores with specialized
plugs
• ORDER DIMARGARITALES
– They are monotypic unlike the Mucorales, they are haustorial
mycoparasites
• ORDER KICKXELLALES
– Produces single‐spores merosporangia, usually from structures called
pseudophialides that are borne on specialized septate or aseptate
fer8le branches called sporocladia
• ORDER ENDOGONALES
– Their sporocarps contain only zygospores and sporangia are unknown
26. DIFFERENCES BETWEEN ORDERS
• ORDER GLOMALES
– They are referred to as VAM fungi or vesicular‐arbuscular
mycorrizae or endomycorrhizae. This group may be found
in 70% of all plant families
• ORDER ENTOMOPHTHORALES
– This group includes the insect pathogens
• ORDER ZOOPAGALES
– The Zoopagales comprises the fungal group with
interac8ons that involve a variety of small animals and
other fungi, although mycoparasi8c species may also be
observed
