Chloridoideae
Chloridoideae is one of the largest subfamilies of grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon'') or goosegrass (''Eleusine indica''), but also millet species grown in some tropical regions, namely finger millet (''Eleusine coracana'') and teff ('' Eragrostis tef''). With the exception of some species in '' Ellisochloa'' and Eleusine indica, most of the subfamily's species use the C4 photosynthetic pathway. The first evolutionary transition from C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene. Phylogeny Relationships of tribes in the Chloridoideae according to a 2017 phylogenetic classification, also showing the Danthonioideae as sister group: The following genera have not been assign ...

Otto Stapf (botanist)
Otto Stapf FRS (23 April 1857, in Perneck near Bad Ischl – 3 August 1933, in Innsbruck) was an Austrian born botanist and taxonomist, the son of Joseph Stapf, who worked in the Hallstatt salt-mines. He grew up in Hallstatt and later published about the archaeological plant remains from the Late Bronze- and Iron Age mines that had been uncovered by his father. Stapf studied botany in Vienna under Julius Wiesner, where he received his PhD with a dissertation on cristals and cristalloids in plants. 1882 he became assistant professor (''Assistent'') of Anton Kerner. In 1887 he was made ''Privatdozent'' (lecturer without a chair) in Vienna. He published the results of an expedition Jakob Eduard Polak, the personal physician of Nasr al-Din, the Shah of Persia, had conducted in 1882, and plants collected by Felix von Luschan in Lycia and Mesopotamia 1881–1883. In 1885, Polak sponsored Stapf to conduct a botanical expedition of his own to South- and Western Persia, which was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Goat-antelope#Tribe Caprini, Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Scilloideae#Hyacintheae, Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form ...

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 forage, 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 bi ...

C4 Photosynthesis
carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960's discovery by Marshall Davidson Hatch and Charles Roger Slack that some plants, when supplied with 14, incorporate the 14C label into four-carbon molecules first. fixation is an addition to the ancestral and more common carbon fixation. The main carboxylating enzyme in photosynthesis is called RuBisCO, which catalyses two distinct reactions using either (carboxylation) or oxygen (oxygenation) as a substrate. The latter process, oxygenation, gives rise to the wasteful process of photorespiration. photosynthesis reduces photorespiration by concentrating around RuBisCO. To ensure that RuBisCO works in an environment where there is a lot of carbon dioxide and very little oxygen, leaves generally differentiate two partially isolated compartments called mesophyll cells and bundle-sheath cells. is initially fixed in the m ...
