Multi-omics analysis reveals distinct responses to light stress in photosynthesis and primary metabolism between maize and rice.

ABSTRACT: High-light (HL) stress is a major environmental factor that limits crop productivity. Maize (Zea mays) and rice (Oryza sativa), two key global crops, can both grow under HL intensities but differ in photosynthetic metabolism; maize is a C₄ species, whereas rice is a C₃ species. However, the molecular mechanisms underlying their responses to HL stress remain poorly understood. To systematically dissect how HL affects maize and rice growth, we conducted time-resolved multi-omics analyses, examining the transcriptome, translatome, proteome, and metabolome in response to HL treatment. Integration of this multi-omics approach with physiological analyses revealed that rice exhibits a more rapid response to HL stress than maize, with significant alterations in photosynthetic
