cop1: a regulatory locus involved in light-controlled development and gene expression in Arabidopsis.

Genes & development - 1 Jul 1991

Deng X W, Caspar T, Quail P H

Abstract excerpt

Light signals from the environment are perceived by specific regulatory photoreceptors in plants and are transduced by unknown mechanisms to genes that control growth and development. We have identified a genetic locus in Arabidopsis thaliana, which appears to play a central role in this transduction process. Mutations in this locus, designated cop1 (constitutively photomorphogenic), result in dark-grown...
