Description
Fushuai Gong and co-authors trace how an alpine rhododendron defends itself against ultraviolet light in a 2024 study. UV-B rays raise the level of reactive oxygen in plant cells, which damages membranes and slows photosynthesis. Plants answer in part by making flavonoids, compounds that absorb UV and mop up the reactive spill. A family of switch proteins called MYB factors helps run that production.
Under UV-B stress, the plant's photosynthetic activity fell while its antioxidant enzymes rose. The team followed one switch-linked gene, RcTRP5, and its grip on the flavonoid pathway. Their work maps the chain from light stress to the gene to the protective compounds. Alpine plants face fierce UV at altitude, so their defense wiring holds lessons for breeding hardier ornamentals and crops.
