Context: "This article describes a parasitic fungi group. For the ascomycete fungi genus, see "Microsporum". For the green algae genus, see "Microspora". For the beetle family, see Microsporidae."
The Microsporidia constitute a group of spore-forming unicellular parasites. They were once considered protozoans or protists, but are now known to be fungi, or a sister group to fungi. Loosely 1500 of the probably more than one million species are named now. Microsporidia are restricted to animal hosts, and all major groups of animals host microsporidia. Most infect insects, but they are also responsible for common diseases of crustaceans and fish. The named species of microsporidia usually infect one host species or a group of closely related taxa. Several species, most of which are opportunistic, also infect humans., Rosopsida ( Batsch , 1788 ) is a botanical name for a group of flowering plants recognized at the rank of class . The name is derived from that of the included family Rosaceae . As used in the Reveal system it is a subset of the dicots , a paraphyletic group recognized at various ranks in other systems , and includes : subclass Caryophyllidae subclass Hamamelididae subclass Dilleniidae subclass Rosidae subclass Cornidae subclass Lamiidae subclass Asteridae Reveal 's use of the group corresponds largely to Cronquist 's class Magnoliopsida ( but minus subclass Magnoliidae ) and to the eudicots of the APG II system minus Ranunculales and some other early - branching groups . The name has not been used in most of the more influential recent classification systems , such as the Cronquist system , the Thorne system , the Takhtajan system or the APG II system ., Oomycota or oomycetes form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms. They are filamentous, microscopic, absorptive organisms that reproduce both sexually and asexually. Oomycetes occupy both saprophytic and pathogenic lifestyles, and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. One oomycete, the mycoparasite "Pythium oligandrum", is used for biocontrol, attacking plant pathogenic fungi. The oomycetes are also often referred to as water molds (or water moulds), although the water-preferring nature which led to that name is not true of most species, which are terrestrial pathogens.
The Oomycota have a very sparse fossil record. A possible oomycete has been described from Cretaceous amber., Protist is an informal term for any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular 5-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues.", A 20th-century system of plant taxonomy, the Reveal system (see also the Thorne & Reveal system) of plant classification was drawn up by the American botanist James Reveal (1941-2015). The system was published online in 1997 in ten parts as lecture notes comparing the major systems in use at that time. Subsequently Reveal became an author with the consensus Angiosperm Phylogeny Group (APG) on the APG II 2003 and APG III 2009 processes. Although this largely supplanted the earlier and competing systems, he collaborated with Robert Thorne on his system (2007), and subsequently continued to develop his own system., Cyanobacteria , also known as Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. The name "cyanobacteria" comes from the color of the bacteria (= blue). Sometimes, they are called blue-green algae, and incorrectly so, because cyanobacteria are prokaryotes and the term "algae" is reserved for eukaryotes., The International Code of Nomenclature for Cultivated Plants (ICNCP), also known as the Cultivated Plant Code, is a guide to the rules and regulations for naming cultigens, plants whose origin or selection is primarily due to intentional human activity. Cultigens under the purview of the ICNCP include "cultivars", Groups ("cultivar groups"), and "grexes". All organisms traditionally considered to be plants (including algae and fungi) are included. Taxa that receive a name under the "ICNCP" will also be included within taxa named under the International Code of Nomenclature for algae, fungi, and plants, for example, a cultivar is a member of a species., The Angiosperm Phylogeny Group, or APG, refers to an informal international group of systematic botanists who came together to try to establish a consensus on the taxonomy of flowering plants (angiosperms) that would reflect new knowledge about plant relationships discovered through phylogenetic studies., A cultigen (from the Latin "cultus"  cultivated, and "gens"  kind) is a plant that has been deliberately altered or selected by humans; it is the result of artificial selection. These "man-made" or anthropogenic plants are, for the most part, plants of commerce that are used in horticulture, agriculture and forestry. Because cultigens are defined by their mode of origin and not by where they are growing, plants meeting this definition remain cultigens whether they are naturalised in the wild, deliberately planted in the wild, or growing in cultivation.
Cultigens arise in the following ways: selections of variants from the wild or cultivation including vegetative sports (aberrant growth that can be reproduced reliably in cultivation); plants that are the result of plant breeding and selection programs; genetically modified plants (plants modified by the deliberate implantation of genetic material); and graft-chimaeras (plants grafted to produce mixed tissue, the graft material possibly from wild plants, special selections, or hybrids)., The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c. 295,383 known species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word ("angeion", "case" or "casing", and "sperma", "seed") meaning "enclosed seeds", after the enclosed condition of the seeds., A botanical name is a formal scientific name conforming to the "International Code of Nomenclature for algae, fungi, and plants" (ICN) and, if it concerns a plant cultigen, the additional cultivar and/or Group epithets must conform to the "International Code of Nomenclature for Cultivated Plants" (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia).", The International Code of Nomenclature for algae, fungi, and plants (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants". It was formerly called the International Code of Botanical Nomenclature (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the "Melbourne Code" which replaces the "Vienna Code" of 2005. As with previous codes, it took effect as soon as it was ratified by the congress (on Saturday 23 July 2011), but the documentation of the code in its final form was not finished until some time after the congressional meeting. Preliminary wording of some of the articles with the most significant changes has been published in September 2011., Rosaceae, the rose family, is a medium-sized family of flowering plants, including 4,828 known species in 91 genera., A rose is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae, or the flower it bears. There are over a hundred species and thousands of cultivars. They form a group of plants that can be erect shrubs, climbing or trailing with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses., Subject: rosopsida, Relation: parent_taxon, Options: (A) angiospermae (B) angiosperms (C) animal (D) cyanobacteria (E) fungi (F) insects (G) magnoliophyta (H) microsporum (I) oomycetes (J) plant (K) prokaryotes (L) protist (M) pythium (N) rosaceae
