Hypersensitive to red and blue 1 and its modification by protein phosphatase 7 are implicated in the control of Arabidopsis stomatal aperture.

PLoS genetics - 1 Jan 2012

Sun Xiaodong, Kang Xiaojun, Ni Min

Abstract excerpt

The stomatal pores are located on the plant leaf epidermis and regulate CO(2) uptake for photosynthesis and the loss of water by transpiration. Their stomatal aperture therefore affects photosynthesis, water use efficiency, and agricultural crop yields. Blue light, one of the environmental signals that regulates the plant stomatal aperture, is perceived by the blue/UV-A light-absorbing cryptochromes and...
