Abstract:
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.
