Fine mapping and characterization of the awn inhibitor B1 lo

发布时间：2021-11-09 17:15

　　Awns play an important role in seed dispersal and photosynthesis of spikes. Three major awn inhibitors（Hd, B1, and B2） are reported in wheat. However, the molecular mechanism underlying awnlessness remained unknown until recently. In this study, we identified two F8 recombinant inbred lines（RILs） that were segregating for awn length. In order to identify the causal gene for awn length in the heterozygous inbred families（HIFs）, SNPs were called from RNA sequencing（RNA-Seq） data for HIF-derived pr...
