is a genus of Sorghum flowering plants in the grass family Poaceae. Seventeen of the 25 species are native to Australia,  with the range of some extending to  Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans.  One species is grown for  grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized, in pasture lands.  Sorghum is in the subfamily Panicoideae and the tribe Andropogoneae (the tribe of big bluestem and sugarcane).
Cultivation and uses
, Sorghum bicolor native to Africa with many cultivated forms now,  is an important crop worldwide, used for  food (as grain and in sorghum syrup or "sorghum molasses"), animal fodder, the production of alcoholic beverages, and biofuels. Most varieties are drought- and heat-tolerant, and are especially important in arid regions, where the grain is one of the staples for poor and rural people. These varieties form important components of forage in many tropical regions. S. bicolor is an important food crop in Africa, Central America, and South Asia, and is the fifth-most important cereal crop grown in the world. 
In the early stages of the plants' growth, some species of sorghum can contain levels of
hydrogen cyanide, hordenine, and nitrates which are lethal to grazing animals. When stressed by drought or heat, plants can also contain toxic levels of cyanide and nitrates at later stages in growth.
Global demand for sorghum increased dramatically between 2013 and 2015 when
China began purchasing US sorghum crops to use as livestock feed as a substitute for domestically grown corn. China purchased around $1 billion worth of American sorghum per year until April 2018 when China imposed retaliatory duties on American sorghum as part of the trade war between the two countries.
