Phot1 and phot2 mediate blue light regulation of stomatal opening.

Nature - 6 Dec 2001

Kinoshita T, Doi M, Suetsugu N, Kagawa T, Wada M, Shimazaki K

Abstract excerpt

The stomatal pores of higher plants allow for gaseous exchange into and out of leaves. Situated in the epidermis, they are surrounded by a pair of guard cells which control their opening in response to many environmental stimuli, including blue light. Opening of the pores is mediated by K(+) accumulation in guard cells through a K(+) channel and driven by an inside-negative electrical potential. Blue light causes...
