Plant growth: A matter of WAK seeing the wall and talking to BRI1

Cell wall signaling impacts plant growth and development, but how wall signals are perceived and transduced remains enigmatic. A new study shows that a rice wall-associated kinase, OsWAK11, senses pectin and alters growth by binding the OsBRI1 receptor. OsWAK11 inhibits OsBRI1 to slow growth and is degraded to speed up growth upon sensing pectin.

This study reveals that a rice wall-associated kinase, OsWAK11, can perceive pectin and regulate growth by binding to the receptor OsBRI1.
