Abstract

Salt stress significantly impacts plant growth, and Tamarix ramosissima Ledeb is utilized for afforestation in China’s saline–alkali regions. Trehalose, an osmoregulatory compound, enhances plant tolerance to salt stress by stabilizing cell membranes and regulating oxidative states and ion distribution. However, its role in mitigating NaCl-induced damage in Tamarix species remains understudied. In this study, root samples of T. ramosissima were exposed to NaCl stress with exogenous K+ at 0 h, 48 h, and 168 h. Analyses revealed that soluble sugar content increased over time, especially in the 200 mM NaCl + 10 mM KCl treatment at 168 h. Transcriptome sequencing identified 19 trehalose-related genes involved in metabolic and sucrose pathways, with Unigene0015746 notably enhancing D-Glucose 6-phosphate accumulation, a key precursor for trehalose synthesis. This gene emerged as a crucial candidate for further research. The transcriptome data were validated using qRT-PCR. Overall, the study elucidates the molecular mechanisms of trehalose-related genes in T. ramosissima under salt stress with exogenous K+, providing valuable genetic resources for breeding salt-tolerant tree species.
