However, there have been few reports on the genome-wide identification of JAZ genes in watermelon and its relationship with fruit ripening. METHODS AND RESULTS: In this study, bioinformatics approaches were employed to identify ClaJAZ genes of watermelon at the genome-wide levels. Further exploration delved into the phylogenetic relationships, chromosomal mappings, promoter dynamics, expression, and architectural features of the JAZ genes. The results showed that a total of 9 ClaJAZ genes unevenly distributed across six chromosomes were identified in the watermelon genome, and they all have conserved Jas and TIFY domains. These JAZ genes were divided into four distinct groups with five genes involved in inter-chromosomal tandem duplication events, and members of the same subgroup exhibited a high degree of similarity in their gene structure and protein motif patterns. Analysis of the promoter regions of the ClaJAZ genes indicated the presence of cis-acting elements associated with hormonal responses, stress, and developmental processes. Gene expression analysis through real-time quantitative PCR (qRT-PCR) showed that there were spatiotemporal differences in the expression of ClaJAZ genes at various stages of fruit development. Among them, ClaJAZ7 has the highest level of transcriptional expression and showed strong promoter activity.

Transcriptome sequencing revealed tissue-specific expression with roots showed the highest levels. Cd stress significantly altered the expression and activity of VrCOXs, particularly in roots and stems, with varied responses among different genes.</p><p><strong>Conclusions: </strong>The differential response of VrCOX s to Cd stress indicates a role in the plant stress tolerance mechanism. The study provides insights into the function of COXs in legumes and a foundation for further research into Cd tolerance mechanisms, which could be vital for enhancing legume production and ensuring food safety in contaminated environments.</p>","PeriodicalId":18755,"journal":{"name":"Molecular Biology Reports","volume":"52 1","pages":"17"},"PeriodicalIF":2.6,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142716469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
