Phytochrome B promotes branching in Arabidopsis by suppressing auxin signaling.

Plant physiology - 1 Mar 2014

Krishna Reddy Srirama, Finlayson Scott A

Abstract excerpt

Many plants respond to competition signals generated by neighbors by evoking the shade avoidance syndrome, including increased main stem elongation and reduced branching. Vegetation-induced reduction in the red light:far-red light ratio provides a competition signal sensed by phytochromes. Plants deficient in phytochrome B (phyB) exhibit a constitutive shade avoidance syndrome including reduced branching. Because...
