Whole-genome DNA methylation reprograms gene expression and flowering in maize under combined high air temperature and natural soil drought (HAT-NSD), linked to 4315 differentially methylated genes.
- Why it matters: Molecular details for how maize responds to and tolerates HAT-NSD, especially through whole genome-wide DNA methylation, remain unclear.
- What they did: The study used multi-level analyses to map WGDM, identify 4315 DMG and 4186 differentially expressed genes (DEG), and relate methylation in CG/CHG/CHH contexts to expression, splicing, and protein abundance.
- The result: Limited effects of WGDM on protein abundance were observed via DMG–DEG–DEP type genes, while methylation-driven reprogramming-feedback involving alternative splicing was proposed to regulate flowering/tasseling.
