TCP Transcription Factors Regulate Shade Avoidance via Directly Mediating the Expression of Both PHYTOCHROME INTERACTING FACTORs and Auxin Biosynthetic Genes.

Abstract excerpt

Light quality surrounding a plant is largely determined by the density of its neighboring vegetation. Plants are able to sense shade light signals and initiate a series of adaptation responses, which is known as shade avoidance syndrome (SAS). PHYTOCHROME INTERACTING FACTORS (PIFs) are key factors in the SAS network by regulating the biosynthesis of multiple phytohormones and the expression of cell expansion...
