Poaceae, also known as the true grasses, is the fourth largest plant family in the world with around 12,000 species and roughly 800 genera. [ 1 ] [ 2 ] They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos , and several important weeds .

Flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. [8]: 12 The spikelets are further grouped into panicles or spikes. The part of the spikelet that ...
Within the order, by far the most important family economically is the family of grasses (Poaceae, syn. Gramineae), which includes the starch staples barley, maize, millet, rice, and wheat as well as bamboos (mostly used structurally, like wood, but somewhat as vegetables), and a few "seasonings" like sugarcane and lemongrass. Graminoids ...

Maize (Zea mays, Poaceae) is the most widely cultivated C 4 plant.[1]In botany, C 4 carbon fixation is one of three known methods of photosynthesis used by plants. C 4 plants increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and salinity.
The Pooideae are the largest subfamily of the grass family Poaceae, with about 4,000 species in 15 tribes and roughly 200 genera. They include some major cereals such as wheat, barley, oat, rye and many lawn and pasture grasses. They are often referred to as cool-season grasses, because they are distributed in temperate climates. [1]
Oryzoideae (syn.Ehrhartoideae) is a subfamily of the true grass family Poaceae.It has around 120 species in 19 genera, notably including the major cereal crop rice. [1] Within the grasses, this subfamily is one of three belonging to the species-rich BOP clade, which all use C 3 photosynthesis; it is the basal lineage of the clade.
