Conceptual model summarizing genotype-specific responses to blue and UV priming, showing relative changes in flavonols, anthocyanins, and photoinhibition compared to no priming conditions. Blue light priming reduces photoinhibition through CRY-dependent signalling, while UV-B provides an additive benefit only when blue signalling is intact; in the absence of CRY, responses shift toward anthocyanin accumulation without reduction of photoinhibition. Arrows up and down reflect an increase and a decrease, respectively. No arrow means no change relative to responses without priming
