![]() ![]() distachyon has been recently challenged by the evolutionary and systematic study of Catalán and coworkers. distachyon germplasm collections have been built at USDA ( ), and in several European and Mediterranean institutions, ,, ,, containing accessions with both economically and ecologically relevant traits and showing large phenetic and genotypic variation for on-going mapping projects. distachyon, which shows an extremely low amount of repetitive DNA, , has facilitated the construction of single-copy BAC libraries for comparative genomics and of derived mutagenized T-DNA and TILLING lines as a further aid to investigate gene expression effects under different natural and induced conditions in the model grass. distachyon, ,, adapted to different environmental conditions, as a suitable plant for ecosystem management and to prevent land erosion. Other studies have highlighted the ecological plasticity of B. Lines of research include studies on grain production, pathogen resistance, and tolerance to drought and to other abiotic stresses that could be transferred to cereal breeding programs, ,, to those on cell wall analyses focused on the improvement of biofuel grass production. Over the last decade, more than 400 laboratories worldwide have worked on investigating the genomics, transcriptomics and metabolomics of B. These features make it an optimal model for the cultivated temperate cereals, wheats and barley, and other Poaceae. ![]() This taxon shows one of the smallest genome sizes of the monocots (272 Mb), together with a short life cycle (6 weeks), an inbreeding nature and a close relationship to the temperate cereals and forage crops. 2802 barcody circle alabama full#The impact of the new model plant Brachypodium distachyon on grass genomic research has gathered pace since the publication in 2010 of the full genome sequence of the diploid genotype Bd21 (2n = 10) by the International Brachypodium Initiative. ![]()
