Brachypodium mutants to accelerate biomass crop breeding

Résumé :
Brachypodium distachyon
emerged recently as model plant for grass crops. With its simple sequenced genome, short life cycle and expanding array of genetic tools, B. distachyon is an excellent system to elucidate the molecular basis of important traits in grasses (e.g. development, grain and biomass production). The small genome size of B. distachyon and recent advances in NGS made it feasible to sequence thousands of mutants to establish a genome-wide sequence-indexed collection of grass mutants. To date, a consortium sequenced a total of 859 mutant lines and identified 804,508 putative SNP mutations and 5,540 putative small deletions. Another 990 mutants are in the sequencing or DNA extraction queue. The collection was extensively validated and characterized using forward and reverse genetics by looking for and characterizing mutations in several genes involved in several traits such as cell wall composition.
