Genome-Wide Characterization of / Gene Family in Cabbage ( var. ): Expression Profiling and Functional Implications During Infection.

Calmodulin (CaM) and calmodulin-like proteins (CMLs) are crucial for calcium signal transduction in plants. Although / genes have been extensively studied in various plant species, research on these genes in is still limited. In this study, 14 and 75 genes were identified in the genome through a genome-wide search. Phylogenetic analysis categorized these genes, along with their homologs in and rice, into six distinct groups. All / genes were unevenly distributed across the nine chromosomes of , with 52 of them lacking introns. Collinearity analysis revealed that / genes in are present in multiple copies in the genome. Moreover, the majority of / genes exhibited distinct expression patterns across the different tissues, indicating their role in the growth and development of . A clustering heatmap of / gene expression showed distinct patterns before and four days after infection, dividing the genes into five groups based on their expression patterns. Notably, is significantly downregulated in both susceptible and resistant materials, suggesting that it plays an important role in responding to infection. This study conducted a comprehensive survey of the gene family in . It could serve as a theoretical foundation for further functional identification and utilization of family members and their role in the interaction between and .
