Because high temperatures impair rice production, it is desirable to elucidate the regulatory mechanisms involved in response heat stress. The objectives of this study were identify candidate genes and characterize their patterns during adaptation at seedling stage. Ten heat-associated quantitative-trait loci identified a genome-wide association study. Comparison transcript abundances heat-sensitive heat-tolerant pools under stress revealed approximately 400 differentially expressed genes. expression from accessions changed more than those Alternative splicing (AS) events responded rice. types AS variants significant different between accessions. Expression differing for known be We eleven associated with response. These could pyramided breed
