Examples of vegatative habit, tillers and floral spikes/spikelets, and seeds of Brachypodium distachyon.Brachypodium distachyon (L.) Beauv has many qualities that make it a model for functional genomics studies in temperate grasses, cereals, and dedicated biofuel crops such as Switchgrass. These attributes include small genome (~300Mbp) diploid accessions, tetraploid and hexaploid accessions, a small physical stature, self-fertility, a short lifecycle, and simple growth requirements.

Brachypodium Genome Published in Nature


From Nature:

The genome of Brachypodium distachyon, a wild annual grass endemic to the Mediterranean and Middle East, has been sequenced. This is the first member of the economically important Pooideae subfamily, which includes wheat and barley, to be sequenced. Comparative genomics using the Brachypodium, rice and sorghum genomes provide insights into genome evolution of the grasses and will aid future analyses of large and complex genomes such as that of wheat. Availability of this genome sequence should help establish Brachypodium, which is easily cultivated and amenable to genetic manipulation, as a model for developing new energy and food crops.
