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.
细胞壁信号影响植物的生长和发育，但细胞壁信号如何被感知和转导仍然是个谜。一项新的研究表明，水稻细胞壁相关激酶 OsWAK11 感知果胶并通过结合 OsBRI1 受体来改变生长。OsWAK11 抑制 OsBRI1 以减缓生长，并在感知果胶时被降解以加速生长。
