Improved Salt Tolerance in <i>Brassica napus</i> L. Overexpressing a Synthetic <i>Deinocuccus</i> Stress-Resistant Module DICW.

ABSTRACT: Salt stress adversely impacts plant physiology by causing ionic, osmotic, and oxidative stress, ultimately hindering growth and yield. The genus Deinococcus contains unique stress resistance genes, and previous studies have shown that proteins such as IrrE, Csp, and WHy enhance stress tolerance in plants and microbial cells. However, their role in Brassica napus L. (oilseed rape) remains unexamined. In this study, a synthetic stress-resistance module, DICW, was constructed using the Deinococcus-derived genes IrrE, Csp, and WHy and heterologously overexpressed in B. napus to assess its impact on salt tolerance. The results demonstrated that the DICW module significantly improved seed germination and seedling growth under salt stress. Transgen
