Zygomycota
Zygomycota, or zygote fungi, is a former phylum, division or phylum of the kingdom Fungi. The members are now part of two Phylum, phyla: the Mucoromycota and Zoopagomycotina, Zoopagomycota. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Some are parasites of plants, insects, and small animals, while others form symbiotic relationships with plants. Zygomycete hyphae may be coenocyte, coenocytic, forming septa only where gametes are formed or to wall off dead hyphae. Zygomycota is no longer recognised as it was not believed to be truly monophyletic. Etymology The name ''Zygomycota'' refers to the zygosporangium, zygosporangia characteristically formed by the members of this clade, in which resistant spherical Zygospore, spores are formed during sexual reproduction. ''Zygos'' is Greek language, Greek for "joining" or "a yoke", referring to the fusion of two hyphae, hyphal strands which produces t ...

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 μm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. ...

Kickxellomycotina
Kickxellomycotina is a fungus grouping in the subkingdom of Zoopagomyceta . The name was changed from "Harpellomycotina", because "Kickxellomycotina" had an older stem. It came from the genus '' Kickxella'', named after Jean Kickx. Orders include Asellariales, Kickxellales, Dimargaritales, and Harpellales.

Dimargaritales
Dimargaritales is a monotypic order of fungi in the monotypic Dimargaritomycetes class within the subdivision of Kickxellomycotina. ''Dimargaritales'' was published in 1979, while ''Dimargaritomycetes'' was published by Tedersoo et al. in Fungal Diversity vol.90, Issue 1 on page 151 in 2018. It is parasitic. But can grow solitary on agar media, thus cold facultative parasite. Only one family, Dimargaritaceae, exists, containing three genera: * Dimargaritaceae **'' Dimargaris'' - 7 spp. **'' Dispira'' - 4 spp. **'' Tieghemiomyces'' - 2 spp. *Dimargaritales incertae sedis or is a term used for a taxonomy (biology), taxonomic group where its broader relationships are unknown or undefined.

Yoke
A yoke is a wooden beam used between a pair of oxen or other animals to enable them to pull together on a load when working in pairs, as oxen usually do; some yokes are fitted to individual animals. There are several types of yoke, used in different cultures, and for different types of oxen. A pair of oxen may be called a ''yoke of oxen'', and yoke is also a verb, as in "to ''yoke'' a pair of oxen". Other animals that may be yoked include horses, mules, donkeys, and water buffalo. Etymology The word "yoke" is believed to derive from Proto-Indo-European *yugóm (yoke), from root *''yewg''- (join, unite), and is thus cognate with '' yoga''. This root has descendants in almost all known Indo-European languages including German ''Joch'', Latin ''iugum'', Ancient Greek ζυγόν (''zygon''), Persian یوغ (''yuğ''), Sanskrit युग (''yugá''), Hittite 𒄿𒌑𒃷 (iúkan), Old Church Slavonic иго (''igo''), Lithuanian ''jungas'', Old Irish ''cuing'', and Armenian ...

Greek Language
Greek (, ; , ) is an Indo-European languages, Indo-European language, constituting an independent Hellenic languages, Hellenic branch within the Indo-European language family. It is native to Greece, Cyprus, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the list of languages by first written accounts, longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts ...

Sexual Reproduction
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete ( haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. In placental mammals, sperm cells exit the penis through the male urethra and enter the vagina during copulation, while egg cells enter the uterus through the oviduct. Other vertebrates of both sexes possess a cloaca for the release of sperm or egg cells. Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. Sexual reproduction also occurs in some unicellular eukaryotes. Sexual reproduction does not occur in pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zygospore
A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists. Zygospores are created by the nuclear fusion of haploid cells. In fungi, zygospores are formed in zygosporangia after the fusion of specialized budding structures, from mycelia of the same (in homothallic fungi) or different mating types (in heterothallic fungi), and may be chlamydospores. In many eukaryotic algae, including many species of the Chlorophyta, zygospores are formed by the fusion of unicellular gametes of different mating types. A zygospore remains dormant while it waits for environmental cues, such as light, moisture, heat, or chemicals secreted by plants. When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released. In fungi, a sporangium is produced at the end of a sporangiophore that sheds spores. A fungus that forms zygospores is called a zygomycete, indicating that the class Class, Classes, or The Class may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
