Hystrix (plant)
''Hystrix'' was a formerly recognized genus of grass (family Poaceae). The genus ''Hystrix'' was created in 1794 by Conrad Moench for the species described as ''Elymus hystrix'' by Carl Linnaeus in 1753. Moench considered that ''E. hystrix'' was sufficiently distinct to be placed in a separate genus as ''Hystrix patula''; the genus was to be used for species without glumes or with long setaceous glumes. Subsequently a number of other grass species were placed in this genus. Genomic studies from the 1960s onwards showed that ''H. patula'' does in fact belong in ''Elymus'', as this is now defined. Other species placed in ''Hystrix'' have genomes more closely resembling those of ''Leymus'' species, and are better placed in that genus. Currently accepted transfers include: * ''Hystrix californica'' → '' Leymus californicus'' * ''Hystrix coreana'' → '' Leymus coreanus'' * ''Hystrix duthiei'' → '' Leymus duthiei'' * ''Hystrix komarovii'' → '' Leymus komarovii'' * ''Hy ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Conrad Moench
Conrad Moench (sometimes written Konrad Mönch; 15 August 1744 – 6 January 1805) was a German botanist, professor of botany at Marburg University from 1786 until his death. He wrote 'Methodus Plantas horti botanici et agri Marburgensis' in 1794, an arranged account of plants in the fields and gardens of Marburg. In 1802 he named the plant '' Gillenia trifoliata'' in a supplement to a local flora of the city of Marburg. He also named the plant genus ''Echinacea'' (1794). The botanical genus ''Moenchia'' (family Caryophyllaceae Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactacea ...) is named in his honor. The standard botanical author abbreviation Moench is applied to plants he described. Principal writings * ''Enumeratio plantarum indigenarum Hassiae praesertim inferioris, sec ...

Elymus Hystrix
''Elymus hystrix'', known as eastern bottlebrush grass, or bottle-brush-grass, is a bunchgrass in the grass family, Poaceae. It is native to the Eastern United States and Eastern Canada. Description ''Elymus hystrix'' is a herbaceous plant with alternate, simple leaves, on erect stems. The flowers are white and bloom in spring. ''Elymus hystrix'' ranges from approximately two and a half to four and a half feet in height. There are usually two spikelets at each of the five to nine nodes of the plant. Unlike some similar native grasses, the blades of ''Elymus hystrix'' do not have glumes surrounding its spikelets. ''Elymus hystrix'' is self-compatible; that is, it can reproduce using its own pollen. ''Elymus hystrix'' is a perennial meaning it does not completely die at the end of each season, but comes back the next year. ''Elymus hystrix'' has four copies of its genome, exhibiting a type of polyploidy called tetraploidy. Taxonomy ''Elymus hystrix'' was first described by Ca ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glume
In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or the flowers of sedges (Cyperaceae). There are two other types of bracts in the spikelets of grasses: the lemma and palea. In grasses, two bracts known as "glumes" form the lowermost organs of a spikelet (there are usually two but one is sometimes reduced; or rarely, both are absent). Glumes may be similar in form to the lemmas, the bracts at the base of each floret This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general. Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary o .... In sedges, by contrast, a glume is a scale at the base of each flower in a spikelet. References {{reflist Plant morphology ...

Genome
In the fields of molecular biology and genetics, a genome is all the genetic information of an organism. It consists of nucleotide sequences of DNA (or RNA in RNA viruses). The nuclear genome includes protein-coding genes and non-coding genes, other functional regions of the genome such as regulatory sequences (see non-coding DNA), and often a substantial fraction of 'junk' DNA with no evident function. Almost all eukaryotes have mitochondria and a small mitochondrial genome. Algae and plants also contain chloroplasts with a chloroplast genome. The study of the genome is called genomics. The genomes of many organisms have been sequenced and various regions have been annotated. The International Human Genome Project reported the sequence of the genome for ''Homo sapiens'' in 200The Human Genome Project although the initial "finished" sequence was missing 8% of the genome consisting mostly of repetitive sequences. With advancements in technology that could handle sequenci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
