A conserved pollen signal unifies intra- and interspecific reproductive barriers in Brassicaceae
Plant Science Research WeeklyDistant hybridization is an important route for crop improvement, enabling the transfer of disease resistance and stress tolerance from wild relatives, but in Brassicaceae it is strongly restricted by stigma-based interspecific incompatibility. While self-incompatibility (SI) signaling via SCR–SRK…
