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 .
Poa [2] is a genus of about 570 species of grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. Poa is Greek for 'fodder'. Poa are members of the subfamily Pooideae of the family Poaceae.

The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
Plant evolution is the subset of evolutionary phenomena that concern plants. Evolutionary phenomena are characteristics of populations that are described by averages , medians , distributions , and other statistical methods.
Oryza sativa belongs to the genus Oryza and the BOP clade in the grass family Poaceae. With a genome consisting of 430 Mbp across 12 chromosomes, it is renowned for being easy to genetically modify and is a model organism for the study of the biology of cereals and monocots. [7]
Each family's formal name ends in the Latin suffix -aceae and is derived from the name of a genus that is or once was part of the family. [ 3 ] The table below contains seed-bearing families from Plants of the World by Maarten J. M. Christenhusz (lead author), Michael F. Fay and Mark W. Chase , with two updated families [ a ] from Plants of the ...
