Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla : the Mucoromycota and Zoopagomycota . [ 1 ] Approximately 1060 species are known. [ 2 ]
Relationships among and within subphyla of Zygomycota are poorly understood, and their monophyly remains in question, so they are sometimes referred to by the informal name zygomycetes. Zoopagomycotina are microscopic and are typically obligate parasites of other zygomycete fungi and of microscopic soil animals such as nematodes , rotifers and ...
Zygomycosis is the broadest term to refer to infections caused by bread mold fungi of the zygomycota phylum. However, because zygomycota has been identified as polyphyletic, and is not included in modern fungal classification systems, the diseases that zygomycosis can refer to are better called by their specific names: mucormycosis [1] (after Mucorales), phycomycosis [2] (after Phycomycetes ...
It is thought that ordinarily two surviving nuclei, one from each parent, fuse to form a diploid cell which then undergoes meiosis to form haploid meiotic products. [ 1 ] [ 2 ] These then reproduce by mitotic divisions leading to the formation of a sporangium structure (germosporangium) that develops out from the zygospore.
In some phyla of fungi, the sporangium plays a role in asexual reproduction, and may play an indirect role in sexual reproduction. The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. [3] Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane.
In hyphae of basidiomycete fungi, parenthesomes (1) "cap" a dolipore septum; (2) the cell wall; (3) swells around the septal pore to form a barrel-shaped ring. Perforations in the parenthesome allow cytoplasm to flow between (4) and (5).
Donald Trump mocked Canadian Prime Minister Justin Trudeau after his top minister’s surprise resignation following a clash on how to handle the president-elect’s looming tariffs.
Mucoromycotina is a subphylum of uncertain placement in Fungi. It was considered part of the phylum Zygomycota, but recent phylogenetic studies have shown that it was polyphyletic and thus split into several groups, it is now thought to be a paraphyletic grouping.
