Integrated transcriptomic and metabolomic analysis unveils heat-tolerance-associated flavonoid metabolites and genes in the rice rel1-D mutant.

ABSTRACT:

Background

Plants have evolved the ability to produce specialized metabolites as a defense mechanism against biotic and abiotic stressors, with flavonoid-mediated defense responses playing a crucial role in this process. Diverse flavonoids are present in various rice-grown resources, and they confer tolerance to different environmental conditions, including high temperature stress. Elucidating the differences in these flavonoids is essential for breeding improved rice varieties with enhanced tolerance to adverse environments. In a previous study, we isolated a dominant rice mutant generated by T-DNA insertion and christened it rolled and erect leaf 1 (hereafter rel1-D), initially identified for its enhanced tolerance to drought stress and its involvement in the regulation of leaf r
