The Arabidopsis Transcriptome Responds Specifically and Dynamically to High Light Stress
Abstract
The dynamic and specific transcriptome for high light (HL) stress in plants is poorly understood because heat has confounded previous studies. Here, we perform an in-depth temporal responsive transcriptome analysis and identify the core HL-responsive genes. By eliminating the effect of heat, we uncover a set of genes specifically regulated by high-intensity light-driven signaling. We find that 79% of HL-responsive genes restore their expression to baseline within a 14-h recovery period. Our study reveals that plants respond to HL through dynamic regulation of hormones, particularly abscisic acid (ABA), photosynthesis, and phenylpropanoid pathway genes. Blue/UV-A photoreceptors and phytochrome-interacting factor (PIF) genes are also responsive to HL. We further show that ABA biosynthesis-defective mutant nced3nced5, as well as pif4, pif5, pif4,5, and pif1,3,4,5 mutants, are hypersensitive to HL. Our study presents the dynamic and specific high-intensity light-driven transcriptional landscape in plants during HL stress.
