Enhancing cold tolerance through HubZIP6-mediated CBF activation and salicylic acid signaling in pitaya
Cold stress severely limits the yield and quality of fruit crops, yet its regulatory mechanisms in pitaya remain poorly understood. Here, we identified a cold-inducible bZIP transcription factor, HubZIP6, that plays a central role in enhancing cold tolerance in pitaya. HubZIP6 is a nuclear-localized protein with transc...
