Zygomycete
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 ...

Mucoromycota
Mucoromycota is a division within the kingdom fungi. They include a diverse group of various molds, including the common bread molds '' Mucor'' and '' Rhizopus''. It is a sister phylum to Dikarya. It consists of mainly mycorrhizal fungi, root endophytes, and plant decomposers; Glomeromycotina, Mortierellomycotina, and Mucoromycotina. Informally known as zygomycetes I, Mucoromycota includes Mucoromycotina, Mortierellomycotina, and Glomeromycotina. Mucoromycotina and Glomeromycotina can form mycorrhiza-like relationships with nonvascular plants. Mucoromycota contain multiple mycorrhizal lineages, root endophytes, and decomposers of plant-based carbon sources. Mucoromycotina species known as mycoparasites, or putative parasites of arthropods are like saprobes. When Mucoromycota infect animals, they are seen as opportunistic pathogens. Mucoromycotina are fast growing fungi and early colonizers of carbon rich substrates. Mortierellomycotina are common soil fungi that occur as ...

Mucorales
The Mucorales is the largest and best studied order of zygomycete fungi. Members of this order are sometimes called pin molds. The term mucormycosis is now preferred for infections caused by molds belonging to the order Mucorales. Systematics The order includes: 11 families, 56 genera, and approximately 300 species. Mucoralean classification has traditionally been based on morphological, developmental, and ecological characteristics. Recently, molecular data has revealed, that some aspects of traditional classification are quite artificial. For example, the Mucoraceae is believed to be polyphyletic, as are the Thamnidiaceae, Chaetocladiaceae and Radiomycetaceae. Some of the genera, (including ''Mucor'', ''Absidia'' and '' Backusella'') appear to be polyphyletic. Today, the traditional system is still largely in use, as further studies are needed to reconcile morphological and molecular concepts of families and genera. Families The order consists of the following familie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucoromycotina
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. Mucoromycotina is currently composed of 3 orders, 61 genera, and 325 species. Some common characteristics seen throughout the species include: development of coenocytic mycelium, saprotrophic lifestyles, and filamentous. History Zygomycete fungi were originally only ascribed to the phylum Zygomycota. Such classifications were based on physiological characteristics with little genetic support. A genetic study of Zygomycete fungi performed in 2016 showed that further classification of the group was possible, thus splitting it into Zoopagomycota, Entomophthoromycota, Kickxellomycotina, and Mucoromycotina. The study put these groups as being sister to Dikarya, but without further research, their exact locations in Fungi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Some plants produce varying numbers of seeds that lack embryos; these are empty seeds which never germinate. Dormant seeds are viable seeds th ...

Entomophthorales
The Entomophthorales are an order of fungi that were previously classified in the class Zygomycetes. A new subdivision, Entomophthoromycotina, has recently been circumscribed for them. Most species of the Entomophthorales are pathogens of insects. A few attack nematodes, mites, and tardigrades, and some (particularly species of the genus '' Conidiobolus'') are free-living saprotrophs. The name Entomophthorales is derived from the Ancient Greek for insect destroyer ('' entomo-'' = referring to insects, and '' phthor'' = "destruction"). Highlighted species * '' Basidiobolus ranarum'', a commensal fungus of frogs and a mammal pathogen * '' Conidiobolus coronatus'', a saprotrophic fungus of leaf litter and a mammal pathogen * ''Entomophaga maimaiga'', a biocontrol agent of spongy moths * ''Entomophthora muscae'', a pathogen of houseflies * '' Massospora'' spp., pathogens of periodical cicadas * ''Pandora'', including '' Pandora neoaphidis'', an obligate pathogen of aphids Bio ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoopagales
The Zoopagales is an order of fungi in the subdivision Zoopagomycotina. Most species are parasites or predators of microscopic animals such as amoebae. They also prey on rotifers. The order contains 5 families, 22 genera, and 190 species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriat ....

Zygosporangium
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 Zygomycota, or zygote fungi, is a former phylum, division or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyphae
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. Th ...
