FHY1: a phytochrome A-specific signal transducer.

Genes & development - 15 Nov 2001

Desnos T, Puente P, Whitelam G C, Harberd N P

Abstract excerpt

Phytochromes are plant photoreceptors that regulate plant growth and development with respect to the light environment. Following the initial light-perception event, the phytochromes initiate a signal-transduction process that eventually results in alterations in cellular behavior, including gene expression. Here we describe the molecular cloning and functional characterization of Arabidopsis FHY1. FHY1 encodes a...
