OXR2 integrates UV-B photomorphogenic signalling, DNA repair, cell cycle regulation, and phenolic compound accumulation in Arabidopsis thaliana.
Ultraviolet-B radiation has a dual effect on plants, acting both as a developmental cue and a source of genetic stress. Plants must balance growth, DNA repair, cell division, and damage mitigation. Oxidation Resistance (OXR) proteins are evolutionarily conserved, TLDc-domain-containing mitochondrial proteins that link...
