phytochromecontaining
Phytochromecontaining is an adjectival descriptor used to identify cells, tissues, organisms, or materials that contain phytochromes—photoreceptor proteins sensitive to red and far-red light. In plants, phytochromes regulate many aspects of growth and development by switching between two stable conformations, Pr (red-absorbing) and Pfr (far-red-absorbing), in response to light. This photoconversion alters phytochrome activity, subcellular localization, and interactions with signaling partners, leading to changes in gene expression and developmental programs.
Phytochromes are found across land plants and in some algae, fungi, and bacteria; bacteriophytochromes and fungal
The term phytochromecontaining may be applied in ecological, physiological, and molecular contexts, for instance to describe
Understanding phytochrome-containing systems informs plant biology, agriculture, and biotechnology by linking light perception to adaptive growth
