Heat stress response factor ZmHSF10 positively regulates heat tolerance in maize.

ABSTRACT: High temperature stress poses a significant threat to the normal growth of maize seedlings, and key heat-resistant gene mining is the molecular basis for breeding new heat-resistant maize varieties. Through transcriptome sequencing of heat-tolerant hybrid ZD819 and its parental lines (ZD819-F, ZD819-M) under high-temperature stress, we identified 12 HSF (Heat shock transcription factors, HSFs) transcription factors from 12,442 differentially expressed genes. The results indicate that the maize hybrid ZD819 has stronger heat tolerance compared to its parent varieties (ZD819-F, ZD819-M). Transcriptome data identified 12 HSFs transcription factors, among which ZmHSF10 had the highest differential expression fold of 1279.40 before and after high-temperature treatment. The heat tolerance functi
