摘　　要：“生物有机体不断优化和完善自身以适应多变的环境,在其进化产生的复杂机制中,植物体内光敏色素系统的精妙调控是无与伦比的”--这句话引自沃伦·L·巴特勒(Warren L.Butler)。人们最初认为这个色素分子参与植物体内广泛的生理反应,包括红光/远红光可逆调控的种子萌发或光周期性开花,后来被命名为光敏色素。“Of the many intricate and beautiful control mechanisms living organisms have evolved to opti‐mize their survival in a variable and changing envi‐ronment,none is more elegant than the phytochrome system of plants.”-This is a quote by Warren L.But‐ler who made seminal contributions to the discovery of the pigment in plants previously described to con‐trol a wide range of physiological responses,includ‐ing red/far-red light reversible seed germination or photoperiodic flowering.I fully share Warren L.But‐ler’s fascination and excitement for this pigment,which was later named phytochrome.This pigment has been part of my daily life since 2003,when I met Eberhard Schäfer,another great and inspiring mind of phytochrome research.Mutant screens,genome se‐quencing and other genetic or molecular approaches pioneered by phytochrome enthusiasts all over the world paved the way to the model for phytochrome signalling that we have today.
