HY4 gene of A. thaliana encodes a protein with characteristics of a blue-light photoreceptor.

Nature - 11 Nov 1993

Ahmad M, Cashmore A R

Abstract excerpt

Specific responses to blue light are found throughout the biological kingdom. These responses--which in higher plants include phototropism, inhibition of hypocotyl elongation, and stomatal opening--are in many cases thought to be mediated by flavin-type photoreceptors. But no such blue-light phot...
