Comparative transcriptome and metabolomics analysis of heat-resistant and heat-sensitive maize hybrids under heat stress at flowering stage

High temperature around flowering has a serious impact on the growth and development of maize. However, few maize genes related to flowering heat stress were confirmed, and the regulatory mechanism is less clear. To reveal the molecular mechanism of maize heat tolerance, two maize hybrids ZD309 and XY335 with different heat resistance were selected to perform transcriptome and metabolomics analysis at flowering stage under heat stress. This is the raw data.
