Phytochrome a-specific signaling in arabidopsis thaliana

Abstract

Among the five phytochromes in Arabidopsis thaliana, phytochrome A (phyA) plays a major role in seedling de-etiolation. Until now, more than 10 positive and some negative components acting downstream of phyA have been identified. However, their site of action and hierarchical relationships are not completely understood yet. © 2011 Landes Bioscience.
