Phytochrome-specific type 5 phosphatase controls light signal flux by enhancing phytochrome stability and affinity for a signal transducer

Article Abstract:

A type 5-protein phosphatase specifically dephosphorylates biologically active Pfrphytochromes and that it enhances phytochrome-mediated photoresponses. Phytochrome photoreceptors are found to develop an elaborate bio-chemical tuning mechanism for modulating the flux of light signal.

Light and brassinosteroid signals are integrated via a dark-induced small G protein in etiolated seedling growth

Article Abstract:

Research demonstrates that a G-protein, Pra2, is dark-induced and regulates the dark-induced P450 that is involved in the brassinosteroid biosynthesis. Data suggest that Pra2 integrates light and brasinosteroid signals during hypocotyl elongation in dark grown plants.
