SUMMARY Tartary buckwheat is known for its ability to adapt intricate growth conditions and possess robust stress‐resistant properties. Nevertheless, it remains vulnerable drought stress, which can lead reduced crop yield. To identify potential genes involved in resistance, a genome‐wide association study on tolerance germplasm was conducted. A gene encoding pectin methylesterase inhibitors protein ( FtPMEI13 ) identified, not only associated with but also showed induction during stress abscisic acid (ABA) treatment. Further analysis revealed that overexpression of leads improved by altering the activities antioxidant enzymes levels osmotically active metabolites. Additionally, interacts (PME) inhibits PME activity response stress. Our results suggest may inhibit FtPME44/FtPME61, thereby affecting methylesterification cell wall modulating stomatal closure Yeast one‐hybrid, dual‐luciferase assays, electrophoretic mobility shift assays demonstrated an ABA‐responsive transcription factor FtbZIP46 , could bind promoter, enhancing expression. indicated accessions genotype resulting higher expression exhibited compared others. This suggests this has application breeding. Furthermore, natural variation responsible decreased domestication. Taken together, these provide basic support breeding tolerance.

High temperature significantly impacts grain appearance quality, yet few studies have focused on identifying new quantitative trait loci (QTLs)/genes related to these traits under heat stress during the flowering stage in rice. In this study, a natural population of 525 rice accessions was used identify QTLs and candidate genes associated with quality using Genome-Wide Association Study stress. We identified 25 length (GL), width (GW), chalkiness (GC) across 10 chromosomes three populations (full, indica, japonica). Notably, sets overlapping were (set 1: qHTT-L3 qHTT-XL3; set 2: qHTT-C5 qHTT-XC5; 3: qHTT-L11.1 qHTT-GL11), located 3, 5, 11, respectively. Haplotype analysis indicated that Hap1 is superior haplotype, pyramiding more than two alleles improved (longer GL, wider GW, lower GC) high-temperature environments. Based RNA-seq, qRT-PCR functional annotations analysis, LOC_Os05g06920, LOC_Os05g06970, LOC_Os11g28104 highly expressed, them as high-priority for linked (GL, Expression revealed which encodes relA-SpoT-like protein RSH4, LOC_Os11g28104, kinase DUF26 domain, expressed seeds, leaves, shoots. And encoding peroxidase precursor, exhibited high expression levels roots. Compared wild-type (WT) plants, mutants increased GL length-to-width ratio, but reduced GW both conditions, while LOC_Os05g06970 chalky rate degree conditions. Furthermore, showed decline WT after treatment. These findings suggest play crucial roles regulating development tolerance at anthesis, thus affecting Our results provide promising genetic resource improving
