They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, [6] wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. [ citation needed ] Some members of the Poaceae are used as building materials ( bamboo , thatch , and straw ); others can provide a source of biofuel , primarily via ...
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 .
It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. [1] In 2009, a linear arrangement of the system was published separately; [ 2 ] the APG IV paper includes such an arrangement, cross-referenced to the 2009 one.
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.

A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
The BOP clade (sometimes BEP clade) is one of two major lineages (or clades) of undefined taxonomic rank in the grasses , containing more than 5,400 species, about half of all grasses. Well-known members of this clade include rice , some major cereals such as wheat , barley , oat , and rye , many lawn and pasture grasses, and bamboos .
