PNAS paper on Capsella speciation published

Self-compatible Capsella rubella and -incompatible C. grandiflora are two closely related and crossable species.

Remarkably, we have now found, in collaboration with other groups from the ERA-PG ARelatives consortium, that C. rubella apparently originated from C. grandiflora only a few tens of thousands of years ago. Allelic diversity patterns in the two species suggest that C. rubella was probably founded by a single individual, as published in PNAS. How phenotypic diversity is distributed in this species, and how it originated, are interesting questions for future research.
