TaCHP encoding C1‐domain protein stably enhances wheat yield in saline‐alkaline fields.

A study published in the Journal of Integrative Plant Biology explores the potential of the zinc finger gene TaCHP to enhance wheat yield in saline-alkaline conditions. The researchers conducted multi-year, multi-site field trials and found that overexpressing TaCHP significantly increased wheat yields in saline-alkaline fields without affecting yields under normal conditions. Genetic variations in the promoter of TaCHP were also identified, with one haplotype (Hap1) conferring greater salt tolerance than the other (Hap2). The study suggests that TaCHP and its tolerant haplotype have promising applications in molecular breeding for stress-tolerant wheat. [Extracted from the article]
