Will provide a platform to accelerate research on grass biomass and wheat

RIKEN CSRS has applied morphological-based growth scale to Brachypodium distachyon (purple false brome). The identity of the growth stages between B. distachyon (which is related to wheat and barley) and the major crop wheat makes possible a comparison of accumulation patterns of metabolites across different growth stages and across under different stress conditions. RIKEN researchers performed comprehensive comparison of metabolic profiles and determined commonalities and specificities in metabolite properties that were dependent on organisms, growth stages, and/or stress conditions. They found a large number of commonalities in accumulated metabolites, indicating that B. distachyon is an appropriate model plant for wheat research. To make the B. distachyon growth scale and morphological properties at each stage publicly accessible, an image library based on the growth scale is available at

This image library is useful for comparing and integrating research data of B. distachyon gathered at different facilities or for different projects, and it will contribute significantly to the global development of herbaceous biomass research. With the progress of data collection of accumulated metabolites for B. distachyon and wheat, these data will serve as a bridge between model plant research and major crop research to contribute the development of basic research on cereal crops.
