Autophosphorylation desensitizes phytochrome signal transduction.

Abstract

Plant red/far-red photoreceptor phytochromes are known as autophosphorylating serine/threonine kinases. However, the functional roles of autophosphorylation and kinase activity of phytochromes are largely unknown. We recently reported that the autophosphorylation of phytochrome A (phyA) plays an important role in regulating plant phytochrome signaling by… (More)
