Genetic and molecular studies are beginning to unravel the complexities of the signaling circuitry that plants use to sense and transduce information concerning the prevailing light environment. The past year has witnessed definition of discrete photosensory roles for phytochromes A and B, the cloning of a gene encoding the first apparent blue-light photoreceptor from any organism, the cloning of genes encoding additional members of the COP/DET/FUS class of light-responsive master regulators, and evidence that G proteins, Ca2+/calmodulin, and cGMP may be signaling intermediates in phototransduction.
遗传学和分子学研究开始揭示植物用于感知和传递有关当前光照环境信息的信号传导通路的复杂性。过去一年见证了对光敏色素A和B不同的光感功能的明确界定，克隆了来自任何生物体的首个明显的蓝光光感受器编码基因，克隆了编码光响应主调控因子COP/DET/FUS类其他成员的基因，以及有证据表明G蛋白、Ca2+/钙调蛋白和环鸟苷酸可能是光信号转导中的信号中间体。
