Phytochrome - Wikipedia
Phytochromes are a class of photoreceptor proteins found in plants, bacteria and fungi. They respond to light in the red and far-red regions of the visible spectrum and can be classed as either Type I, which are activated by far-red light, or Type II that are activated by red light. [2] .
光敏色素 - 百度百科
吸收红光-远红光可逆转换的光受体（色素蛋白质），称之为光敏色素（phytochrome）。 光敏色素分布在植物各个器官中，黄化幼苗的光敏色素含量比绿色幼苗多20~100倍。
Phytochrome - an overview | ScienceDirect Topics
Phytochrome is a soluble protein that regulates various responses of plants to light. Not all but most of the phytochrome responses are accompanied by changes in the pattern of gene expression. Upon light activation, phytochrome is imported into the nucleus by the nuclear localization activity of the carboxy-terminal half of the molecule.

2024年9月5日 · Phytochromes are specialized photoreceptor proteins predominantly found in plants, but also present in bacteria and fungi. These proteins are essential for detecting light in the red and far-red regions of the visible spectrum.
Phytochrome in Plants - Definition, Structure, Types
Phytochrome refers to the photoreceptor or photomorphogenic pigment, which absorbs red and far-red light wavelengths to induce photomorphogenesis or a light-induced growth and development in various plants, bacteria etc.
Phytochrome Signaling Mechanisms - PMC
2004年7月6日 · There are five distinct phytochromes in Arabidopsis thaliana, designated phytochrome A (phyA) to phyE. phyA is light-labile and is the primary photoreceptor responsible for mediating photomorphogenic responses in FR light, whereas phyB-phyE are light stable, and phyB is the predominant phytochrome regulating de-etiolation responses in R light ...
