Tristachyideae
Tristachyideae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native to tropical and subtropical regions of Africa, Asia, and South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion o .... There are around 70 species in eight genera. The tribe belongs to a basal lineage within the subfamily, and its genera were previously placed in tribes Arundinelleae or Paniceae, subfamily Arundinoideae, or the now-obsolete subfamily Centothecoideae. Species in this tribe use the C4 photosynthetic pathway.

Centothecoideae
Panicoideae is the second-largest subfamily of the Poaceae, grasses with over 3,500 species, mainly distributed in warm temperate and tropical regions. It comprises some important agricultural crops, including sugarcane, maize (or corn), Sorghum bicolor, sorghum, and switchgrass. C4 carbon fixation, C4 photosynthesis evolved independently a number of times in the subfamily, which presumably had a C3 carbon fixation, C3 ancestor. Description The ligule has a fringe of hairs. The inflorescence is branched around a common axis. The spikelets are all alike with two bisexual florets that are joined below the glumes (the outer floral envelopes). The lower glume is shorter than the spikelet. Systematics and taxonomy Within the PACMAD clade of grasses, the Panicoideae are sister to a clade made of the four subfamilies Arundinoideae, Chloridoideae, Danthonioideae, and Micrairoideae. A modern phylogenetic classification divides the Panicoideae in twelve tribe (biology), tribes correspon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

C4 Carbon Fixation
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 1960s discovery by Marshall Davidson Hatch and Charles Roger Slack. 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. RuBisCO oxygenation gives rise to phosphoglycolate, which is toxic and requires the expenditure of energy to recycle through photorespiration. photosynthesis reduces photorespiration by concentrating around RuBisCO. To enable RuBisCO to work in a cellular environment where there is a lot of carbon dioxide and very little oxygen, leaves generally contain two partially isolated compartments called mesophyll cells and bundle-sheath cells. is initially fixed in the mesophyll cells in a reaction catalysed by th ...

Paniceae
Paniceae is a large tribe (biology), tribe of the subfamily Panicoideae in the grasses (Poaceae), the only in the monotypic taxon, monotypic supertribe Panicodae. It includes roughly 1,500 species in 84 genera, primarily found in tropical and subtropical regions of the world. Paniceae includes species using either of the C4 carbon fixation, C4 and C3 photosynthesis, C3 photosynthetic pathways, as well as presumably intermediate species. Most of the millets are members of tribe Paniceae. The tribe is subdivided into seven subtribes, but some genera are as yet unplaced (''incertae sedis''). Species in the Paniceae have an ancestral chromosome number (monoploid number) of ''x'' = 9, while species with ''x'' = 10 formerly included are now recognised as separate tribe, Paspaleae.
