Mycosarcoma
''Mycosarcoma'' is a genus of fungus including ''Mycosocarma maydis'' (sometimes called ''Ustilago maydis)'', or 'corn smut fungus'. ''Mycosarcoma'' was an old retired genus name that was resurrected in 2016, based on new genetic evidence, to better organize species that were previously thought unrelated. The six recognized species were in different genera originally until genetic testing showed their relations and they were reclassified as ''Mycosarcoma''.

Mycosarcoma Maydis
Corn smut is a plant disease caused by the pathogenic fungus ''Mycosarcoma maydis'', synonym (taxonomy), synonym ''Ustilago maydis''. One of several cereal crop pathogens called smut (fungus), smut, the fungus forms galls on all above-ground parts of corn species such as maize and teosinte. The infected corn is edible; in Mexico, it is considered a delicacy, called , often eaten as a filling in quesadillas and other tortilla-based dishes, as well as in soups. Etymology In Mexico, corn smut is known as (, sometimes spelled ). This word entered Spanish in Mexico from Classical Nahuatl, though the Nahuatl words from which is derived are debated. In modern Nahuatl, the word for is (), and some sources deem to be the classical form. See entries for "huitlacoche" and "cuicacoche o cuiltacoche". Some sources wrongly give the etymology as coming from the Nahuatl words ("excrement" or "rear-end", actually meaning "wikt:excrescence, excrescence") and ("sleeping", from "to s ...

Corn Smut
Corn smut is a plant disease caused by the pathogenic fungus ''Mycosarcoma maydis'', synonym ''Ustilago maydis''.

Basidiomycota Genera
Basidiomycota () is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. More specifically, Basidiomycota includes these groups: agarics, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and '' Cryptococcus'', the human pathogenic yeast. Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. However, some Basidiomycota are obligate asexual reproducers. Basidiomycota that reproduce asexually (discussed below) can typically be recognized as members of this division by gross similarity to others, by the fo ...

Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Here ''sets of chromosomes'' refers to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair—the form in which chromosomes naturally exist. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more sets of chromosomes. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in a ...

Teliospore
Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi (Rust (fungus), rusts and Smut (fungus), smuts), from which the basidium arises. Development They develop in ''telium, telia'' (sing. ''telium'' or ''teliosorus''). The telial host is the primary host in heteroecious rusts. The aecial host is the alternate host (look for pycnium, pycnia and Aecium, aecia). These terms apply when two hosts are required by a heteroecious rust fungus to complete its life cycle. Morphology Teliospores consist of one, two or more Dikaryon, dikaryote cells. Teliospores are often dark-coloured and thick-walled, especially in species where they overwinter (acting as chlamydospores). Two-celled teliospores formerly defined the genus ''Puccinia''. Here the wall is particularly thick at the tip of the terminal cell which extends into a beak in some species. Teliospores consist of Dikaryon, dikaryote cells. As the teliospore cells germinate, the cell nucleus, nuc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
