Phytochrome-mediated light signalling in Arabidopsis

Curr Opin Plant Biol. 2004 Oct;7(5):564-9. doi: 10.1016/j.pbi.2004.07.004.

Abstract

The phytochrome photoreceptors regulate all major transitions during the life cycle of plants. The role of each member of the phytochrome family in Arabidopsis is starting to be understood, and a molecular description of phytochrome-regulated flowering time and shade avoidance is emerging. Recent publications have challenged some areas of well-accepted models concerning phytochrome signalling. Moreover, the importance of proteolysis during phytochrome signalling is becoming very apparent.
