Life cycle of zygomycetes in Rhizopus stolonifer
Zygomycota is a division of fungi that includes two classes - zygomycetes and trichomycetes. Zygomycetes have about 1060 species that are mostly terrestrial, living in soil or decaying matter. They reproduce both sexually through the formation of zygospores and asexually via sporangiospores. Trichomycetes are a smaller class found associated with the guts of aquatic insect larvae where they form thalli but do not penetrate the host tissues.
This document provides information about ascomycetes, a phylum of fungi that reproduces sexually through spore-filled structures called asci. It discusses the structure of ascomycetes including their hyphae and septa. Examples of ascomycetes are described such as yeasts like Saccharomyces cerevisiae, the pathogenic Pneumocystis jirovecii, and edible mushrooms like Morchella esculenta. The life cycle and references are also summarized.
There are three main types of reproduction in algae: vegetative, asexual and sexual. Vegetative reproduction occurs through fragmentation, cell division or the formation of specialized structures like hormogones, tubers or adventitious branches. Asexual reproduction happens through the formation of spores like zoospores, aplanospores or autospores which develop into new algae. Sexual reproduction includes isogamy, anisogamy and oogamy where gametes fuse to form zygotes or oospores that develop into new organisms. Sexual reproduction provides benefits like increasing genetic diversity and adaptation to changing environments.
This document provides an overview of Myxomycotina (slime molds). It discusses that they are fungus-like organisms characterized by an amoeboid vegetative phase without cell walls. The document outlines the key characteristics and life cycles of the four classes: Acrasiomycetes, Hydromyxomycetes, Myxomycetes, and Plasmodiophoromycetes. It also briefly discusses their economic importance in nutrient cycling and use in laboratory studies due to their protoplasm without cell walls.
This document provides information about zoosporic fungi. It discusses that zoosporic fungi are true fungi that reproduce asexually through flagellated spores called zoospores. They are divided into three classes based on the flagellation of zoospores: Chytridiomycetes, Hypochytridiomycetes, and Oomycetes. Important information about the characteristics, structures, life cycles, orders, and examples of economically important species are provided for each class.
Deuteromycota refers to fungi that reproduce asexually and whose sexual reproduction cycle is unknown. They are characterized by septate mycelium and reproduce through conidia. There are four orders within Deuteromycota distinguished by where conidia and conidiophores are produced. Some Deuteromycota have sterile mycelium or sclerotia and some undergo a parasexual cycle involving plasmogamy and haploidization but not true meiosis.

The document summarizes key information about Zygomycota (zygote fungi):
1) Zygomycota is a division of fungi that reproduces both asexually through sporangiospores produced in sporangia, and sexually through conjugation forming a zygospore.
2) They are characterized by coenocytic (mostly aseptate) hyphae and the formation of zygospores during sexual reproduction.
3) A major 2001 taxonomic change found the phylum Zygomycota to be polyphyletic, distributing its taxa among the phylum Glomeromycota and four subphyla.

This document outlines Ainsworth's 1973 classification system for fungi. It proposes the kingdom Mycota, divided into the divisions Myxomycota (slime molds) and Eumycota (true fungi). Eumycota is further divided into several subdivisions including Mastigomycotina, Zygomycotina, Ascomycotina, Basidiomycotina, and Deuteromycotina. Each subdivision contains multiple classes and orders of fungi classified based on characteristics like cell structure, life cycle stages, and reproductive structures. The classification aims to group fungi based on morphology and natural relationships rather than previous artificial systems.
This document provides information about myxomycetes (plasmodial slime molds). It discusses that myxomycetes contain 5 orders, 14 families, 62 genera and 888 species. The somatic phase is represented by a multinucleate, apparently naked acellular slimy protoplasmic mass called the plasmodium. At fruiting time, the entire plasmodium is organized into sporangia or sporophores that bear spores. Myxomycetes are classified into three subclasses based on characteristics of the plasmodium and spore-bearing structures.
Fungi are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem. Fungi reproduce both sexually and asexually, and they also have symbiotic associations with plants and bacteria.
Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found in a wide variety of organic substances , including "mature fruits and vegetables", jellies, syrups, leather, bread, peanuts, and tobacco.
Heterokaryosis is the co-existence of genetically different nuclei in a common cytoplasm. It plays a major role in variability and sexuality in fungi. Heterokaryosis can arise through mutation, anastomosis (fusion of hyphae), or inclusion of dissimilar nuclei in spores after meiosis in heterothallic fungi. Parasexuality is a form of genetic recombination in fungi achieved through mitotic crossing over and haploidization without meiosis. The parasexual cycle involves the establishment of heterokaryosis, formation of heterozygous diploids through nuclear fusion, occasional mitotic crossing over during diploid multiplication, and eventual haploidization through aneuploidy. This process
Zygomycetes are non-motile fungi that reproduce asexually through sporangiospores contained in sporangia or aplanospores. Sexual reproduction occurs through gametangial copulation to form zygospores. They have coenocytic, aseptate hyphae with chitin in their cell walls. Zygomycetes are found in soil and decaying matter and include the orders Mucorales and Entomophthorales. Some zygomycete genera like Rhizopus and Mucor are important in food production and can also cause diseases in humans and plants.
This document discusses black rust of wheat, caused by the fungal pathogen Puccinia graminis tritici. Black rust primarily affects wheat stems, appearing as elongated reddish-brown pustules. It completes its disease cycle on wheat plants and barberry bushes. Symptoms include merging pustules that eventually turn black. Control methods include removing barberry bushes, mixed cropping, chemical fungicides, and developing resistant wheat varieties.
Agaricus is a genus of mushrooms containing both edible and poisonous species, with possibly over 300 members worldwide. The genus includes the common ("button") mushroom (Agaricus bisporus) and the field mushroom (A. campestris), the dominant cultivated mushrooms of the West.
Fungi can never be classified in the kingdoms Plantae or Animalia because:
- Fungi are non-motile (lack mobility) unlike animals which are motile.
- Fungi reproduce via spores unlike plants which reproduce via seeds and animals which reproduce sexually.
- Fungi are heterotrophs that absorb nutrients externally from their environment unlike plants which produce their own food via photosynthesis. Animals obtain nutrients internally through ingestion and digestion.
- Fungi lack chloroplasts and chlorophyll for photosynthesis unlike plants. They also lack organized tissues like plants.
- Fungi are more similar to protists in their nutrition and some reproductive characteristics. But they
Ultrastructure of fungal cell and different type ofjeeva raj
This document is a seminar report submitted by Jeeva Raj Joseph on the ultrastructure of fungal cells and different types of spores. It discusses the key components of the fungal cell, including the cell wall, plasma membrane, cytoplasm, organelles, and inclusions. It describes the different types of septa that can divide fungal hyphae. The report also examines the two main types of asexual spores - sporangiospores and conidia - and provides details on different subtypes like arthrospores, blastospores, and phialospores. Finally, it briefly discusses sexually produced spores and how certain spore types are characteristic of different fungal taxa.
The document discusses the phylum Basidiomycotina and provides details about three major classes: Uredinomycetes, Ustomycetes, and Basidiomycetes. It focuses on characteristics of rust fungi (order Uredinales) and smut fungi (order Ustilaginales), including that rusts require two hosts to complete their lifecycle and are obligate parasites, while smuts are facultative saprophytes. Specific examples of the rust fungus Puccinia graminis and the smut genus Ustilago are also outlined.
Heterothallic species have sexes that reside in different individuals. . The term is applied particularly to distinguish heterothallic fungi, which require two compatible partners to produce sexual spores, from homothallic ones, which are capable of sexual reproduction from a single organism.
This document provides information on the classification of Deuteromycotina (fungi imperfecti). It discusses their key characteristics such as reproducing asexually through spores called conidia and lacking a sexual stage. The classes of Deuteromycotina are described as Hyphomycetes, Coelomycetes, and Blastomycetes. Hyphomycetes produce conidia directly on their substrate or in specialized fruiting structures. Coelomycetes produce conidia inside enclosing structures like pycnidia or acervuli. Blastomycetes are yeast-like and propagate by budding. Examples and characteristics of each class are given.
This video is about sexual reproduction in fungi. Sexual reproduction methods like Gametic copulation, Gamete-Gametangial copulation, Gametangial copulation, Somatic copulation and Spermatization are detailed well. Different sexual spores like ascospores, basidiospores, zygospores and oospores, their formation and properties are explained.
Oomycetes, commonly known as water molds, are eukaryotic organisms that are closely related to algae. They include some of the most devastating plant pathogens, causing diseases like late blight of potato and downy mildew of grapevines. Oomycetes reproduce both sexually, through the formation of gametangia and fertilization leading to thick-walled oospores, and asexually via motile zoospores or non-motile sporangia. While they were long classified as fungi, genetic evidence shows they are more closely related to algae and plants. Key differences from true fungi include having cell walls composed of cellulose and lacking chitin.

The document summarizes key evolutionary tendencies in the kingdom Monera. It describes Monera as the oldest and simplest living organisms, including bacteria and cyanobacteria. Bacteria first evolved approximately 3.2-3.5 billion years ago, as evidenced by gene sequencing and ancient microfossils. Cyanobacteria were among the first organisms to evolve oxygenic photosynthesis approximately 2.45 billion years ago, introducing oxygen into the atmosphere. Actinomycetes are a group of bacteria that share characteristics with fungi and play an important role in decomposing organic materials in soil.
The document discusses the transport of organic nutrients through the phloem tissue in plants. It describes how photosynthesis produces sugars in source tissues like leaves, which are then actively loaded into the sieve tube elements and companion cells of the phloem. This loading creates pressure that pushes the phloem sap from sources to sinks, where the sugars are unloaded to support growth and storage. Key components of the phloem discussed include sieve plates, sieve-tube members, companion cells and the pressure-flow hypothesis to explain long-distance translocation of nutrients from sources to sinks throughout the plant.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
6. Introduction :
Zygomycota or zygote fungi is a division of fungi
It is also known as conjugated fungi
They are mostly terrestrial in habitat
Zygomycota has two classes:
1.Zygomycetes
2.Trichomycetes
8. Classes of Zygomycota:
Zygomycetes: Trichomycetes :
.Its has so many economics
importance and has many
orders.
It includes individuals
belonged to insects.
It is not very important
economically
9. Introduction:
Zygomycota, a group of 1090 species included in 181
genera is defined by the presence of a thick walled
resting spores are called zygospores and the
absence of falagellum
Asexual reproduction takes places usually by the
aplanospores(non motile) or arthrospores.
Spores are produced in sporangia
Spores are dispersed by the wind , water, brusting of
sporangia ,rain or animals
11. Characteristics of
Zygomycota:
Zygomycota , all true fungi, produced cell wall contain
chitin
Somatic phase as mycelia, hyphae which are generally
coenocytic because they lack cross walls of septa
Gametangial copulation is a type of sexual
reproduction in Zygomycota in general the gametangia
fuse with each other, lose their identity and develop
into a zygospore
Most reproduce asexually by producing
sporangiospores
12. Class Zygomycetes:
It is characterized by the presence of conenocytic
hyphae,absence of motile cells
Asexual reproduction ususlly by non-motile
sporangiospores
Sexual reproduction is done by gametangial copulation
that results in the formation of a zygospores with in
zygosporangium
The members may either be saprobic in nature or weak
parasite of plants, or specialized parasites of animals or
obligates parasites of fungi including other members of
Zygomycetes
13. General characters:
Life cycle is non motile
It can reproduced both asexually and sexually.
Asexually reproduced by:
1.Aplanospores
2.Sporangiospores
It comprise about 1060 species,including commom
bread molds,as well as both freshwater and marine
species
Most have rapidly growing hyphae, but some are
unicellular
14. Continue …
Zygomycetes hyphae may be coenocytic, forming
septa only where reproductive structure are formed.
Most species of Zygomycetes are live in soil . Or on
decaying plant and animal matter
Aquatic species are primarily found in sediments or
algae, but some species are free-floating or attached
to aquatic animals or decaying leaves
Some are parasites of plants, insects, or small soil
animals. Still other causes serious infections in
human and domestic animals
15. Continue …
The different genera may be distinguished based on
the size and shape of the sporangia, presence or
absence of rhizoids and their location
Zygomycetes carry out the sexual reproduction by
means of spores produce thick walled sexual
structures called Zygosporangia which can remain
dominant for long time
16. Continue …
These sporangia, many Zygotes produce
multiple sporangiospores inside a single
sporangium
Some multiple small sporangia that
contain only few sporangiospores, even a
single one.
18. Classification of
Zygomycetes:
Traditionally ,earlier zygomycetes was classified into
7 orders
Following are the names of these 7 orders:
1. Mucorales
2. Entomophthorales
3. Zoopagales
4.Glomales
20. 1.Mucorales
The order Mucorales is characterized by chiefly
scprobic forms which reproduced by nonmotile but
sometimes appendaged sporangiospores born in
sporangia , merosporangia or as one-spored
sporangia or ‘conidia’
This order contain 47 genera and 130 species
The member of this order are commonly known as
‘pin mold’ because of their sporangia which appear
as black dots in the cobweb like hyphae
21. Mucorales:
Some are important in
spoiling food common
bread molds, storage
diseases of fruit and
vegetables.
Some infects human
and animals
opportunistic
pathogens.
22. Black Bread Mold:
Species of Rhizopus are important in the soft rot of
the sweet potatoes and in the so called ‘leak’ of
strawberries , raspberries , peaches and other fruits
Some other members of the Rhizopus are found in
stored grain like Rhizopus , Mucors, Abisidia
Rizopus species commonly cause rapid spoilage of
bread and one of its species R.solonifer referred to
as the Black bread mold
24. 12 Families recognized by Kirk et
al in this order:
1.Chaetocladiaceae 2.Choanephoraceae
3.Cunnighamellaceae 4.Gilbertellaceae
5.Mucoraceae 6.Mycotyphacea
7.Phycomycetaceae 8.Pilobolaceae
9.Radiomycetaceae 10.Saksenaeaceae
11.Syncephalastraceae 12.Thamnidiaceae
25. 2.Entomophthorales:
This is the small group of fungi, consisting of 22 genera
and 182 species
These species are chiefly parasitic on insects while
others may be parasitic on desmids or ferns prothalli ,
a few being saprobic in soil , drugs or plants debris.
Asexual reproduction is take place by asexual
propagules that are termed both ‘spores’ and ‘conidia’
Sexual reproduction takes place by the fusion of equal
or unequal gametangia and results in thick-walled
zygospore with two to three layers
26.
27. 6 Families of this order:
1.Ancylistaceae 2.Basidiobolaceae
3.Completoriaceae 4.Entomophthoraceae
5.Neozygitaceae 6.Meristacraceae
29. Order Zoopagales:
Zoopagales is a large order consisting of 21 genera
and 163 species of economics importance
These mostly occurring as mycoparasites and
predacious parasites of nematodes, amoebae and
other small terrestrial animals
Asexual reproduction takes place by conidia or
meroporangia that may be of five kinds
Sexual reproduction results in the formation of
zygospores
30. 5 Families of Zoopagales
1.Cocholonemataceae 2.Helicocephalidaceaa
3.Piptocephalidaceae 4.Sigmoideomycetaceae
5.Zoopagaceae
31. Reproduction asexually by sporangiospores within a
special sac called sporangium in most of the order of
zygomycetes, conidia in the Entomophthorales and
arthospores in some Trichomycetes
Sporangium types (4types):
1.True Sporangium
2.Sporangioles
3. Monosporous sporangium
4.Merosporangium
32. Types of sporangium:
1. True sporangium _ True large spores
containing
2. Sporangiols _ Much smaller in size than true
sporangia
No columella produced and few spores (1-50)
3.Monosporous sporangium _(one-spored
sporangium)
4.Merosporangium_ sac containing 10-15
sporangiospores that occur
33. Group of Mucorales:
1. Multispored sporangia _ Mucoraceae,
Pilobolaceae, Mortierellaceae (also produces few-
spored and monoporous sporangiola),
Saksenaeaceae, Choanephoraceae (also produces
monosporous sporangiola).
2. Few-spored sporangiola_
Radiomycetaceae, Thamnidiaceae.
35. Sexual reproduction:
Gametangial copulation is a type of sexual
reproduction
Sexual spores are called zygospores contained with in a
zygosporangium
Most of them are heterothallic
Heterothallism: requiring a partner for sexual
reproduction
Homothallism: able to reproduce sexually without a
partner exhibited among species in phylum
They reproduce sexually when environmental
conditions becomes unfavorable
37. To produce sexually , two opposing mating strains
must fuse or conjugate, leading to karyogamy.
To developing diploid zygospore have thick coats
that protects them from other hazards. They remain
dormant until environmental codition become
favorable.
When the zygospores germinates , it undergoes
meiosis and produce haploid spores.
Grown in to a new organism.
40. Life cycle of Zygomycota:
Vegetative mycelium is haploid, reproduces asexually
by producing sporangiospores in sporangia.
In a heterothallic species, when two compatible
strains come together, hyphal progametangia.
Septa form, producing multinucleate gametangia and
suspensors.
Plasmogamy occurs end wall of gametangia dissolve
and cytoplasm of gametangia mixes.
42. Life cycle…..
Zygospores forms the inside zygosporangium.
Zygospores develops thick wall, warty appearance,
dark in color.
Karyogamy occurs at different times in zygospores
formation in different species, so zygospore in
diploid at some point.
When zygospores germinates, meiosis occurs to
start the haploid portion of the life cycle.
43. Cycle…
Mycelia of different mating types (-) and (+) forming
hyphal extension (gametangia) which each of the
mycelia encloses several haploid nuclei.
During plasmogamy, a zygosporangium forms,
containing multiple haploid nuclei from the two
parents.
44. Cycle…
The zygosporangium develops a rough and thick-
walled coating that can resist harsh condition for
month.
When the condition are favorable , karyogamy
occurs, then later, the meiosis also occurs.
During meiosis, the zygosporangium germinates into
a sporangium on a short stalk.
45. Cycle….
Next, the sporangium disperses genetically diverse
haploid spore.
The spores germinate and grow into new mycelia.
Asexual reproduction :
Mycelia can also reproduce asexually by forming
sporangia that produce genetically identical haploid
spore.
