Brachypodium distachyon, recently developed model system for temperate grasses, exhibited many traits with cereal crops and proposed to be an experimental system to access the biological approach. These traits have shown a surprised degree of phenotypic variation in many collected accessions. Like some important economical cereals, Bdistachyon also belongs to subfamily Pooideae, which make it become an unquestionable model system to research the economically important crops, such as wheat, barley and several potential biofuel plants. Recently, genome sequence and annotation of Bdistachyon has been finished. Associated with the development of the functional genomics and other experimental resources establishment, Bdistachyon will provide a key resource for improving cereal crops and facilitate the approach of sequence analyze gene expression and functional resources available for a variety of species. In this article we review and assess the current progress of Bdistachyon as a model system and then focus specifically on recent studies of comparative genomics, biological improvement, transformation and TDNA mutations.

Key words: Brachypodium distachyon, Model system, Comparative genomics, Biological improvement, Transformation, T-DNA mutations
