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.

摘要

光敏色素是调节植物生长和发育各个方面的光感受器。在本期《细胞》杂志中，柳等人（2005年）表明，5型蛋白磷酸酶PAPP5作用于一种具有生物活性的光敏色素，提高其稳定性以及对下游信号转导器的亲和力，从而增强植物的光反应。
