Is Allomyces a Chytridiomycota?
Some examples of the Chytridiomycota are Allomyces, a water mold, Synchytrium endobioticum, a pathogen of potato, and Neocallimastix, a chytrid that lives symbiotically in the gut of herbivores, such as cattle.
What is Allomyces scientific name?
Allomyces macrogynus is a species of fungus in the family Blastocladiaceae. It was first described by mycologist Ralph Emerson in 1941 as a variety of Allomyces javanicus, and later given distinct species status in 1954.
Is Allomyces unicellular or multicellular?
There is some controversy about the placement of certain fungi into the Chytridiomycota, and there is some evidence to support that the multicellular forms, such as Allomyces and other members of the Blastocladiales, should be placed in a new phylum, the Blastocladiomycota.
Where are Allomyces found?
Allomyces is most commonly found in humid soil within the tropics, although it has been identified in many different regions of the world. Its life cycle can alternate between two stages, gametophytic and sporophytic, reflecting its capacity of both sexual and asexual reproduction.
How old are Chytridiomycota?
Molecular clock estimates hypothesize that the chytrids are an ancient group that inhabited the Earth at least 1.5 Ga (gigaannum=billion years) ago, or even earlier (Heckman et al., 2001; Hedges et al., 2004).
Where does Allomyces get its nutrients?
Saprotrophic fungi obtain their food from dead organic material and are ecologically useful decomposers. Parasitic fungi feed on living organisms (usually plants), thus causing disease. To feed, both types of fungi secrete digestive enzymes into the nutritive surface on which they are growing.
What phylum is Allomyces?
According to traditional taxonomy, Allomyces macrogynus was a member of the Blastocladiales in the Chytridiomycota (chytrids), one of the four major phyla of Fungi.
Where does Allomyces get its nutrients from?
How do fungi obtain nutrition? Saprotrophic fungi obtain their food from dead organic material and are ecologically useful decomposers. Parasitic fungi feed on living organisms (usually plants), thus causing disease.
What does Chytridiomycota look like?
Chytridiomycota cells are coenocytic with no distinction between individual cells. The filaments are long and tubular with a cytoplasm lining and large vacuole in the center. These single-celled organisms have branching hyphae with rhizoids and produce gametes with flagelli.
Is Chytridiomycota good or bad?
They live saprophytically and parasitically. Because Chytridiomycota often feed on decaying organisms, they are important decomposers. While this is an important function, Chytridiomycota can also have a negative impact on human produce, particularly Synchytrium endobioticum, the species that causes potato wart.
Can humans spread chytrid fungus?
It is important to recognise that humans may contribute to the transmission or spread of the chytrid fungus within and among amphibian populations.
