Thermosensor OsTT3.1 enhances rice thermotolerance by degrading OsGSK2 to reduce OsHsfB2c phosphorylation and nuclear translocation.
Heat stress significantly impacts rice productivity, making understanding of molecular mechanisms crucial for crop improvement. Here, we report a regulatory pathway in rice that integrates a membrane-localized E3 ubiquitin ligase (OsTT3.1), glycogen synthase kinase 2 (OsGSK2), and the heat shock factor B2c (OsHsfB2c) t...
