CHAPTER 2 FUNGAL REPRODUCTION asci basidia Zygosporangia Motile spore Four Major Groups of Fungi … The species of ascomycetes are called the sac fungi because they produce sexual pores within the sac-like vascus. Plasmogamy . The sex organs are completely absent and their function has been taken over by the somatic hyphae which are heterothallic. Looks like you’ve clipped this slide to already. However, a few species of Agaricus, like A. campestris and A. bisporus, are homothallic. Therefore mycology is the study of fungi. Only one parent is needed in asexual reproduction, and the offspring produced are genetically identical, eg reproduction in bacteria, production of spores. ADVERTISEMENTS: Some of the important methods of reproduction in Fungi are as follows: 1. Dimorphism occurs in response to environmental factors, of which no one common factor regulates the morphological switch in all dimorphic fungi. Examples include mushrooms, moulds, yeast.

The mode of reproduction is sexual or asexual. Each fragment develops into a new individual. Reply Delete. Ø Fungi may be monoecious (bisexual) or dioecious (unisexual), Ø Moneoecious species produce two sex organs (male and female) in the same thallus, thus they are called homothallic In fungi asexual reproduction is a more common method than sexual reproduction. Holocarpic fungi, Ø Eukarpic fungi: In most fungi only a part of the vegetative mycelium forms the reproductive unit and the rest remain vegetative, such a fungi is called eukarpic fungi (advanced type), Ø Holocarpic fungi: in some unicellular forms the whole vegetative cell is transformed to a reproductive unit at the time of maturation (primitive type).

Eukarpic fungi Mold-Yeast Dimorphism. Ø In sexual reproduction of fungi, the two compatible nuclei (male and female) are brought together by the following processes. Fungi can reproduce in a variety of ways both sexually and asexually. Sexual reproduction in fungi, as in other living organisms, involves the fusion of two nuclei that are brought together when two sex cells (gametes) unite.

Reproduction in organisms 1. As a part of the initiation phase in sexual reproduction cycle, compatible haploid hyphae come together. Asexual reproduction, which is simpler and more direct, may be accomplished by various methods. 1. a Asexual reproduction in fungi involves the rapid production and release of large numbers of spores which can be distributed over a wide area and will grow rapidly into new individuals. Fungus - Fungus - Sexual reproduction: Sexual reproduction, an important source of genetic variability, allows the fungus to adapt to new environments. Four classifications of Fungi Threadlike - produce spores in their threadlike hyphae (ex. REPRODUCTION Fungi reproduce by the production of spores Fungal spores can be either asexual or sexual . After animals and plants, fungi are the third largest kingdom of eukaryotic organisms. Some fungi have the ability to alternate between a mold form and a that of a yeast form -dimorphic fungi. Ø Planogametic copulation involves the fusion of two naked motile gametes (planogametes), Ø Based on the structure and size of fusing gametes, three types of planogamy is can occur in fungi, Ø Fusing gametes are morphologically similar but physiologically they are two strains (+ and -), Ø The gametes are formed on different thalli, Ø Fusing gametes are both morphologically and physiologically different, Ø Male gamete is smaller and active than female gametes, Ø Female gametes are larger and less active than male gametes, Ø Male game is smaller and motile (flagellated), Ø They are formed on specialized reproductive structures called antheridium, Ø Oogamy is an advanced type of sexual reproduction, Ø Here gametes are not released from gametangia, Ø Instead male and female gametangia come in close contact with help of fertilization tube, Ø Then one or more male nuclei migrate in to the female gametangium, Ø The gametangia never fuse or lose their identity during the sexual act, Ø Male and female gametangia are called antheridia and oogonia (Ascogonium in Ascomycetes) respectively, Ø Here the entire content of two compatible gametangia fuse each other, Ø The gametangia come in close contact, wall at the point of contact dissolves and their contents mix each other, (adsbygoogle=window.adsbygoogle||[]).push({}), Ø In some advanced fungi sex organs are completely absent, Ø Here sexual process is accomplished by minute spore like spermatia and specialized (receptive) hyphae acting as male and female structures respectively, Ø Spermatia is carried by air, water or insect to the receptive hyphae, Ø Spermatia attached to the trichogyne of receptive hyphae and migrate in to the cytoplasm, Ø Occurs in advanced fungal groups such as Basidiomycetes, Ø Two vegetative cells or vegetative hyphae take over the sexual function and fuse together, Ø Zygospores are formed by the fusion of male and female structures during sexual reproduction, Ø They are thick walled resting spores of some fungi, Ø Usually produced by lower groups of fungi, Ø Fungal species which produce zygospores are grouped in the class Zygomycete (Rhizopus), Ø Sexual spores produced in the class Ascomycetes, Ø Ascospores are produced in specialized sac like structure called ascus, Ø Typically a single ascus contain eight ascospores, Ø The eight ascospores are produced after a meiosis, immediately followed by a mitosis, Ø Sexual spores produced in the class Basidiomycetes, Ø Basidiospores are produced on specialized structure called basidium, Ø Typically single basidium produce four basidiospores, Ø The four basidiospores are produced after the meiosis of a diploid zygote, Learn more: Vegetative reproduction in fungi, Learn more: Asexual reproduction in fungi, Get our Updates on Mycology in your E-mail Inbox Asexual spore of fungi: Spore formation is the characteristic feature of fungi. 3.

Spores may be produced either directly by asexual methods or indirectly by sexual reproduction.

Ø Dioecious forms produces sex organs in separate thalli, hence called heterothallic The species of ascomycetes are called the sac fungi because they produce sexual pores within the sac-like vascus. Ø Plasmogamy is the first phase of sexual reproduction in fungi, Ø It is the fusion of protoplasts of two compatible gametes or sex cells or hyphae, Ø As a result of plasmogamy, two compatible nuclei are come close to each other, Ø Fusion of two nuclei to form a diploid nucleus, Ø In some fungi (Phycomycetes) karyogamy occurs immediately after plasmogamy, Ø In some other fungi (Ascomycetes and Basidiomycetes) karyogamy is much delayed, Ø In the latter case (delayed karyogamy) two opposite strains of nucleoli get themselves arranged in pairs (dikaryon) in a single cell, Ø This dikaryon divide mitotically as usual along with the simultaneous division of cytoplasm, Ø This results in the establishment of a separate karyotic phase in the life cycle of fungi, Ø This phase of life cycle is called dikaryotic phase, Ø The process by which the dikaryotic phase is accomplished is called dikaryotization, Ø After the establishment of dikaryotic phase, the two nuclei of a dikaryon fuse to form the diploid zygote, Ø Zygote is the only diploid phase in the life cycle of fungi, Ø Zygote immediately undergo reduction division (meiosis) to produce meiospores, Ø After karyogamy reduction division takes places in the diploid nucleus and thus haploid stage is established. 2. (Division Basidiomycota) This division includes mushrooms, rusts, smuts, puffballs, bracket fungi and some yeasts. In both sexual and asexual reproduction, fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Most people see them as plants because they typically grow in soil and do not move around like animals in the search for food; supermarkets sell edible mushrooms such as white mushrooms and shiitake. Ø Fungi reproduce by vegetative, asexual and sexual methods Ø This post describes the Sexual Reproduction methods in fungi Ø Sexual reproduction takes place in all groups of fungi except Deuteromycetes Ø Fungi may be monoecious (bisexual) or dioecious (unisexual).
