The Capsella rubella genome and the genomic consequences of rapid mating system evolution

Stephen Wright, Detlef Weigel and colleagues report the whole-genome sequence of Capsella rubella , a highly selfing crucifer found throughout much of southern and western Europe. They compare mixed-stage flower bud transcriptomes from C. rubella and C. grandiflora , finding a shift in expression of genes associated with flowering phenotypes and providing insights into the transition to selfing.
