Zygomycota, or zygote fungi, are a division of fungi. The name of the division comes from zygosporangia, resistant structures formed during sexual reproduction. There are approximately 600 species of zygomycetes known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Zygomycete hyphae are coenocytic, with septa only where gametes are formed. In biology, the equivalent of a phylum in the plant or fungi kingdom is called a division. ...

Reproduction

A common example of a zygomycete is black bread mold (Rhizopus stolonifer). It spreads over the surface of bread or other food sources, sending hyphae inward to absorb nutrients. In its asexual phase it develops bulbous black sporangia at the tips of upright hyphae, developing hundreds of haploid spores inside that are dispersed into the air. If environmental conditions deteriorate and mycelia of opposite mating types are present, the fungus reproduces sexually and produces zygosporangia. Zygosporangia are highly resilient to environmental hardships, and are metabolically inert. When conditions improve, however, they develop and release haploid spores.

Mycelium is the vegetative part of a fungus consisting of a mass of branching threadlike hyphae that exists below the ground or within another substrate. ... Mating type is the term applied to fungal hyphae that are found to have 2 or more distinct allele sites, distinguishing them as being either male, or female. It is necessary to have different mating types meet in order to have sexual reproduction. ...


Some zygomycetes disperse their spores in a more precise manner than simply allowing them to drift aimlessly on air currents. Pilobolus, a fungus which grows on animal dung, bends its sporangium-bearing hyphae towards light with the help of a light sensitive pigment and then "fires" them with an explosive squirt of high-pressure cytoplasm. Sporangia can be launched as far as 2m, placing them far away from the dung and hopefully on vegetation which will be eaten by an herbivore, eventually to be deposited as dung elsewhere. Pilobolus, the arts organism, germinated in the fertile soil of a Dartmouth College dance class in 1971. ... Organelles. ...


Phylogeny

The Zygomycota, such as the Ann Thornhill strain H7:053, a variant of the mycotic fungi are generally placed at the base of the fungal phylogenetic tree, having diverged from other fungi after chytrids. However, molecular phylogenetic investigation zygomycetes to be a polyphyletic grouping of a number of different evolutionary lineages. Order Glomales was removed in 2002 and elevated to Division Glomeromycota due their lack of zygospore formation, among other pieces of evidence. A phylogenetic tree, also called an evolutionary tree or a tree of life, is a tree showing the evolutionary interrelationships among various species or other entities that are believed to have a common ancestor. ... Orders Chytridiales Spizellomycetales Monoblepharidales Blastocladiales Neocallimasticales Chytridiomycota is a division of the Fungi kingdom and contains only one class, Chytridiomycetes. ... It has been suggested that this article or section be merged into molecular systematics. ... In biology, a taxon is polyphyletic if it is descended from more than one root form (in Greek poly = many and phyletic = racial). ...

Zygomycota - MicrobeWiki (875 words)
Zygomycota are commonly thought of as bread molds, but there are many species of fungi within this classification that form symbiotic relationships with plants or infect animal hosts.
Zygomycota is a classification that encompasses many different species with very different genome structures.
In Zygomycota, sexual reproduction is the fusion of undifferentiated isogametangia or anisogametangia.
Zygomycota (3177 words)
Zygomycota are thought to have a zygotic or haplontic life cycle (Figure 4).
Zygomycota are heterotrophic and typically grow inside their food, dissolving the substrate with extracellular enzymes, and taking up nutrients by absorption rather than by phagocytosis, as observed in many protists.
Zygomycota are thought to have diverged from the remaining fungi before the colonization of land by plants 600-1,400 million years ago (Berbee and Taylor 2001; Heckman et al.
