Genome-wide Analysis of Rice OsDREB1 Genes Under Heat Stress Reveals Functional Specialization of OsDREB1F for Thermotolerance in Arabidopsis

Key Points

• OsDREB1F demonstrates significant thermotolerance under heat stress conditions, highlighting its role.
• Gene expression analysis revealed a distinct response profile for OsDREB1F compared to other OsDREB1 genes.
• Observational analysis across multiple rice varieties under heat stress evaluated the functional specialization of OsDREB1 genes.
• These findings suggest potential genetic targets for improving heat tolerance in rice crops.
