Overexpression of the Lipid Transfer Protein Gene <i>SpLTP1</i> from Desert Pioneer Plant <i>Stipagrostis pennata</i> Enhances the Drought Tolerance in <i>Arabidopsis</i>.

ABSTRACT: Lipid transfer proteins (LTPs) play crucial regulatory roles in plant growth, development, and abiotic stress responses. Stipagrostis pennata is a species of grass widely distributed in arid and semi-arid regions, particularly adapted to desert and steppe environments. Under extreme drought conditions, it exhibits a variety of physiological and morphological adaptation mechanisms, making it an important species for studying plant drought tolerance. Recently, LTPs have been found to exhibit upregulated expression under drought stress in plants such as wheat and tobacco, enhancing their drought tolerance. However, the functional role of LTPs in S. pennata remains unexplored. In this study, the SpLTP1 gene was isolated from S. pennata via molecular cloning, encodin
