Increased leaf photosynthesis caused by elevated stomatal conductance in a rice mutant deficient in SLAC1, a guard cell anion channel protein.

Journal of experimental botany - 1 Sept 2012

Kusumi Kensuke, Hirotsuka Shoko, Kumamaru Toshiharu, Iba Koh

Abstract excerpt

In rice (Oryza sativa L.), leaf photosynthesis is known to be highly correlated with stomatal conductance; however, it remains unclear whether stomatal conductance dominantly limits the photosynthetic rate. SLAC1 is a stomatal anion channel protein controlling stomatal closure in response to envi...
