  • Pre-zygotic reproductive barriers are a vital defence against interspecific pollen transfers in plants. This study shows that SPRI2/SRS7, a transcription factor, regulates the formation of interspecific reproductive barriers in Arabidopsis.

  • STIGMATIC PRIVACY 1 (SPRI1) encodes a stigma-specific plasma membrane protein. It ensures intraspecific fertilization by rejecting pollen tubes of distantly related species in a manner independent of self-incompatibility, thus functioning as an interspecies barrier mechanism.

  • Plants have developed a variety of molecular ways to express self-incompatibility (SI) that promote outcrossing by preventing self-fertilization. A new study reveals that Citrus uses the S-RNase as the key molecule for expressing SI, giving us further evidence that the S-RNase system is widespread and evolved in an early branch of angiosperms.
