The structure of Arabidopsis phytochrome A reveals topological and functional diversification among the plant photoreceptor isoforms
Plants employ a divergent cohort of phytochrome (Phy) photoreceptors to govern many aspects of morphogenesis through reversible photointerconversion between inactive Pr and active Pfr conformers. The two most ...

Plant phytochrome B is an asymmetric dimer with unique signalling potential
Many aspects of plant photoperception are mediated by the phytochrome (Phy) family of bilin-containing photoreceptors that reversibly interconvert between inactive Pr and active Pfr conformers1,2. Despite extensi...

Open AccessPhotosensing and Thermosensing by Phytochrome B Require Both Proximal and Distal Allosteric Features within the Dimeric Photoreceptor
Phytochromes (Phys) encompass a diverse collection of bilin-containing photoreceptors that help plants and microorganisms perceive light through photointerconversion between red light (Pr) and far-red light (P...

Structural basis for selective activation of ABA receptors
The synthetic ABA agonist pyrabactin helped identify the PYR/PYL family of ABA receptors. Now the selectivity of pyrabactin toward specific members of this family is explained using genetic, chemical and struc...
