Mingfang Zhang, Sally Mackenzie and colleagues report the genome sequence of allopolyploid Brassica juncea and through comparative analysis suggest that A-subgenome evolution contributes to differences in agricultural subvarieties. They find that differential homoeolog gene expression from the subgenomes helps to shape the selection that distinguishes vegetable- and oil-use Brassica.
