Phy tunes: phosphorylation status and phytochrome-mediated signaling

Cell. 2005 Feb 11;120(3):290-2. doi: 10.1016/j.cell.2005.01.023.

Abstract

Phytochromes are photoreceptors that regulate various aspects of plant growth and development. In this issue of Cell, Ryu et al. (2005) show that PAPP5, a type 5 protein phosphatase, acts on a biologically active phytochrome, increasing its stability and affinity for a downstream signal transducer and thus enhancing plant photoresponses.
