摘要： Grapes are economically significant fruit trees cultivated globally, but they are often affected by various abiotic stresses. Plant annexins are a class of calcium-dependent phospholipid-binding proteins that play crucial roles in regulating plant growth, development, and stress responses. However, the functions of grape annexins (VvANNs) remain relatively poorly understood. In this study, a total of 21 VvANNs were identified from the grape genome and categorized into six groups based on phylogenetic analysis. The conserved domains, motifs, cis-acting elements, and gene structures of VvANNs were further analyzed. Moreover, real-time quantitative polymerase chain reaction (RT-qPCR) analysis was performed; most VvANNs exhibited significant up-regulation when grape plantlets were treated with polyethylene glycol (PEG), cold, ABA, and salt stress. Given that VvANN8 was significantly up-regulated under salt stress, we selected VvANN8 for further investigation; results showed that the expression of VvANN8 in Arabidopsis enhanced salt tolerance by regulating reactive oxygen species (ROS) accumulation. This study provides a valuable foundation for the in-depth understanding of the VvANN gene family and comprehensively reveals the crucial role of VvANN8 in responding to salt stress.
