The Zoopagomycotina are a subdivision (incertae sedis) of the fungal division Zygomycota sensu lato. [1] It contains 5 families and 20 genera. [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.
The name Zygomycota refers to the zygosporangia characteristically formed by the members of this clade, in which resistant spherical spores are formed during sexual reproduction. Zygos is Greek for "joining" or "a yoke ", referring to the fusion of two hyphal strands which produces these spores, and -mycota is a suffix referring to a division ...
[2] [8] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea. However, some processes in bacteria, including bacterial conjugation, transformation and transduction, may be considered analogous to sexual reproduction in that they incorporate new genetic information. [9]
The study of reproduction and development in organisms was carried out by many botanists and zoologists.. Wilhelm Hofmeister demonstrated that alternation of generations is a feature that unites plants, and published this result in 1851 (see plant sexuality).
[8] [9] [10] The songs of birds, insects and many other animals are part of a ritual to attract potential partners of their own species. The song presents specific patterns recognizable only by members of the same species, and therefore represents a mechanism of reproductive isolation.
Endogonales is an order of fungi within the phylum of Zygomycota, [2] and in class Endogonomycetes. [3] [4] It contains 2 families; Endogonaceae, with 6 genera and 38 species and Densosporaceae, with one genera and 4 species. [3]
Instead, ionocytes are found along the skin, yolk sac, and fins of the larva. [8] As growth progresses and the gill becomes more developed, ionocytes can be found on the gill arch and gill filament. [ 9 ] [ 10 ] In larval fishes, the number, size, and density of ionocytes can be quantified as a relative ionocyte area, which has been proposed as ...
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", [2] jellies, syrups, leather, bread, peanuts, and tobacco.
