摘要
Sorghum is highly tolerant to alkaline stress,but the underlying mechanisms are not well understood.Here,based on genotypic difference in alkaline tolerance of sorghum,it was found that AT1(Alkaline tolerance 1)encoding a G protein is involved in alkaline tolerance through negatively modulating the phosphorylation level of PIP2,an aquaporin with transport activity for H_(2)O_(2).Knockout of AT1 releases its inhibition of PIP2,thereby resulting in an increased transport of H_(2)O_(2)from the cytosol into the apoplast,subsequently boosting alkaline tolerance.
