The Gene <i>SiPrx</i> from <i>Saussurea involucrata</i> Enhances the Stress Resistance of <i>Silphium perfoliatum</i> L.

ABSTRACT: Peroxiredoxin (Prx) plays a role in maintaining the balance of intracellular reactive oxygen species. The peroxidase SiPrx gene from the Tianshan Snow Lotus (Saussurea involucrata) has been proved to significantly enhance the stress resistance of plants. In this study, the SiPrx gene was expressed heterogeneously in high-quality herbage Silphium perfoliatum L. (SP). After treatment with NaCl, the transgenic SP only exhibited partial leaf wilting, whereas the wild-type (WT) plants were on the brink of death. Simultaneously, physiological and biochemical assays indicated that under high-salt conditions, the content of malondialdehyde in the transgenic plants was significantly lower than that in the WT plants, while the activity of antioxidant enzymes was significa
