Disruption of ROOT PHOTOTROPISM2 gene does not affect phototropin-mediated stomatal opening.

Abstract excerpt

Phototropins (phot1 and phot2), blue light-receptor protein kinases in plants, mediate stomatal opening by activating the plasma membrane H(+)-ATPase in guard cells, but the signaling from phototropins to the H(+)-ATPase remains unknown. A recent study concluded that ROOT PHOTOTROPISM2 (RPT2) is involved in the primary step of this process. However, this conclusion is based solely on the determination of stomatal...
