CRISPRa-driven activation of IbbZIP11 boosts saline-alkali tolerance in sweet potato by reinforcing antioxidant defense
Saline-alkali stress limits the cultivation of sweet potato (Ipomoea batatas) on marginal lands, yet the key tolerance genes remain poorly characterized. This knowledge gap is compounded by the crop's heterozygous hexaploid genome, where allelic diversity and genetic redundancy complicate functional genomics studies....
