Mining of the CULLIN E3 ubiquitin ligase genes in the whole genome of .

CULLIN (CUL) proteins are E3 ubiquitin ligases that are involved in a wide variety of biological processes as well as in response to stress in plants. In , genes have not been characterized and its role in plant development, stress response and secondary metabolite synthesis have not been studied. In this study, genome-wide analyses were performed to identify and to predict the structure and function of of . Eight genes were identified from the genome of . The genes were clustered into four subgroups according to phylogenetic relationships. The CUL domain was highly conserved across the family of genes. Analysis of -acting elements suggested that genes might play important roles in a variety of biological processes, including abscission reaction acid (ABA) processing. To investigate this hypothesis, we treated hairy roots of with ABA. The expression of genes varied obviously after ABA treatment. Co-expression network results indicated that three genes might be involved in the biosynthesis of phenolic acid or tanshinone. In summary, the mining of the genes in the whole genome of contribute novel information to the understanding of the genes and its functional roles in plant secondary metabolites, growth and development.
