N2 - The genus Barbarea has emerged as a model for evolution and ecology of plant defense compounds,due to its unusual glucosinolate profile and production of saponins, unique to the Brassicaceae. Onespecies, B. vulgaris, includes two ‘types’, G-type and P-type that differ in trichome density, and theirglucosinolate and saponin profiles. A key difference is the stereochemistry of hydroxylation of theircommon phenethylglucosinolate backbone, leading to epimeric glucobarbarins. Here we report a draftgenome sequence of the G-type, and re-sequencing of the P-type for comparison. This enables us toidentify candidate genes underlying glucosinolate diversity, trichome density, and study the geneticsof biochemical variation for glucosinolate and saponins. B. vulgaris is resistant to the diamondbackmoth, and may be exploited for “dead-end” trap cropping where glucosinolates stimulate ovipositionand saponins deter larvae to the extent that they die. The B. vulgaris genome will promote the study ofmechanisms in ecological biochemistry to benefit crop resistance breeding.
