| Abstract | (1) Background: Hippophae gyantsensis, a drought-tolerant plant native to the Tibetan Plateau, plays a crucial ecological and economic role. While its drought tolerance mechanisms have been extensively studied, the role of alternative splicing (AS) in drought resistance remains insufficiently explored. This study aims to elucidate how AS events regulate gene expression to enhance drought tolerance in H. gyantsensis under water-deficit conditions. (2) Methods: H. gyantsensis plants were subjected to progressive drought stress followed by rehydration. Physiological responses, transcriptomic data, and hormonal profiles were analyzed to investigate the plant's adaptive mechanisms to drought stress, with a particular focus on abscisic acid (ABA) signaling-related genes. (3) Results: The results showed that H. gyantsensis maintained high leaf water content even under severe drought stress, emphasizing its strong drought resistance. A transcriptomic analysis revealed 11,962 differentially expressed genes, primarily enriched in hormone signaling and metabolic pathways. Notably, the accumulation of ABA was closely associated with AS events in ABA-related genes, such as ZEPs, ABCG, and PP2C. These genes produced multiple splice variants, indicating their role in modulating the ABA signaling pathway and enhancing drought tolerance. (4) Conclusions: This study highlights the pivotal role of AS in ABA signaling and drought tolerance in H. gyantsensis. It provides new insights into how AS contributes to plant adaptation to drought stress, bridging the knowledge gap in drought resistance mechanisms and emphasizing the importance of AS in plant stress responses. |
