A new study provides a comprehensive molecular mechanism that controls interspecific incompatibility of self-incompatible (SI) plants in the Brassicaceae. This finding points to a potentially promising path to break interspecific barriers and achieve introgression of desirable traits into crops from distant species among SI crops in the Brassicaceae.
