The Xyloglucan endotransglucosylase/hydrolase (XTH) family, a group of cell wall-modifying enzymes, plays crucial roles in plant growth, development, and stress adaptation. The quality and yield of Chinese jujube (Ziziphus jujuba) fruit are significantly impacted by environmental stresses, including excessive salinity, drought, freezing, and disease. However, there has no report of the XTH encoding genes present in Chinese jujube genome and their response transcription level under various stresses. This study provides an in-depth analysis of ZjXTH genes in genome of Chinese jujube and elucidating their structural motifs, regulatory networks, and expression patterns under various stresses. A total of 29 ZjXTH genes were identified from Ziziphus jujuba genome. Phylogenetic analysis classifies ZjXTH genes into four distinct groups, while conserved motifs and domain analyses reveal coordinated xyloglucan modifications, highlighting key shared motifs and domains. Interaction network predictions suggest that ZjXTHs may interact with proteins such as Expansin-B1 (EXPB1) and Pectin Methylesterase 22 (PME22). Additionally, cis-regulatory element analysis enhances our understanding of Chinese jujube plant's defensive systems, where TCA- and TGACG-motifs process environmental cues and orchestrate stress responses. Expression profiling revealed differential regulation of ZjXTH genes under various stress conditions. Under salt stress, ZjXTH1 was upregulated, while ZjXTH6, and ZjXTH13 were downregulated, with ZjXTH3 and ZjXTH19 exhibiting negative regulation. In response to drought, ZjXTH5 showed upregulation, whereas ZjXTH7, -25, -13 were downregulated, and ZjXTH13 and ZjXTH19 were negatively regulated. Furthermore, under cold conditions, ZjXTH14 and ZjXTH18 were upregulated, while ZjXTH22, -23, -28, -29 were downregulated, and ZjXTH20 exhibited negative regulation. Additionally, phytoplasma infection induced the upregulation of ZjXTH1, -3, -5, with ZjXTH6, -7, -11, -16, -25 being downregulated, and ZjXTH20 showing negative regulation. Collectively, these findings deepen our understanding of the functional roles of Chinese jujube XTHs, emphasizing their regulatory function in adaptive responses in Chinese jujube plants.
