- TaHST2 is a heat stress tolerance (HST) gene in wheat that underwent functional silencing during domestication.
- Silencing of TaHST2, a negative regulator of basal HST, improved thermotolerance in cultivated wheat through intronic polymorphisms and epigenetic modifications.
- TaHST2 encodes a ubiquitin hydrolase that stabilizes HST repression proteins TaHSC701 and TaHSC702, modulating heat response pathways.
- The study suggests that synthetic hexaploidy and octoploid wheat could be used to breed heat-resilient varieties.
- The research was funded by the China Postdoctoral Science Foundation and the National Natural Science Foundation of China.
