hy8, a new class of arabidopsis long hypocotyl mutants deficient in functional phytochrome A.

The Plant cell - 1 Jan 1993

Parks B M, Quail P H

Abstract excerpt

Emerging evidence suggests that individual members of the phytochrome family of photoreceptors may regulate discrete facets of plant photomorphogenesis. We report here the isolation of phytochrome A mutants of Arabidopsis using a novel screening strategy aimed at detecting seedlings with long hypocotyls in prolonged far-red light. Complementation analysis of 10 selected mutant lines showed that each represents an...
