- Abstract
This study explores CAMTA genes in the rare and endangered Chinese plant species, Liriodendron chinense. Despite the completion of whole-genome sequencing, the roles of CAMTA genes in calcium regulation and stress responses in this species remain largely unexplored. Within the L. chinense genome, we identified two CAMTA genes, Lchi09764 and Lchi222536, characterized by four functional domains: CG-1, TIG, ANK repeats, and IQ motifs. Our analyses, including phylogenetic investigations, cis-regulatory element analyses, and chromosomal location studies, aim to elucidate the defining features of CAMTA genes in L. chinense. Applying Weighted Gene Co-Expression Network Analysis (WGCNA), we explored the impact of CAMTA genes on different organs and their regulation under abiotic stress conditions. The identification of significant gene modules and the prediction of promoter binding sites revealed co-expressed genes associated with CAMTA transcription factors. In summary, this study provides initial insights into CAMTA genes in L. chinense, laying the groundwork for future research on their evolution and biological roles. This knowledge enhancement contributes to a better understanding of plant responses to environmental stress--an essential aspect of plant biology.
