Characterization of an Arabidopsis thaliana Mutant Identified in a Genetic Screen for Altered Red Light Responses

Abstract

Perception of light is crucial for a plant's survival. Plants can perceive red (~670nm) and far-red (~730nm) wavelengths of light via cellular light receptors known as phytochromes. The Gingerich lab has observed the participation of two genes, LRB (Light-Regulating BTB) 1 and LRB2, in the red-light signaling pathway. To better understand the function of the LRB1 and LRB2 genes and the red light signaling pathway, this study conducted a genetic suppressor screen to identify other genes which participate in the red light pathway.
