Poaceae Poales, but the seagrasses are members of order Alismatales. The name Poaceae was given by John Hendley Barnhart in 1895, based on the tribe Poeae described in 1814 by Robert Brown, and the type genus "Poa" described in 1753 by Carl Linnaeus. The term is derived from the Ancient Greek . Grasses include some of the most versatile plant life-forms. They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung (coprolites) have been found containing phytoliths of a variety that include grasses that are related to modern rice and bamboo. Grasses have adapted to conditions in
Waikavirus Waikavirus Waikavirus is a genus of viruses in the order Picornavirales, in the family Secoviridae. Plants, poaceae, cyperaceae, and gramineae serve as natural hosts. There are currently three species in this genus including the type species Rice tungro spherical virus. Diseases associated with this genus include: MCDV: plant stunting and chlorotic striping of tertiary leaf veins in maize. Group: ssRNA(+) Viruses in Waikavirus are non-enveloped, with icosahedral geometries, and T=pseudo3 symmetry. The diameter is around 30 nm. Genomes are linear, around 12kb in length. Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host
