Summary:Plant-specific TCP transcription factors play vital roles in the controlling of growth, development, and the stress response processes. Extensive researches have been carried out in numerous species, however, there hasn't been any information available about genes in sweet potato ( L.). In this study, a genome-wide analysis of genes was carried out to explore the evolution and function in sweet potato. Altogether, 18 were identified and cloned. The expression profiles of the differed dramatically in different organs or different stages of leaf development. Furthermore, four CIN-clade genes contained miR319-binding sites. Blocking significantly increased the expression level of and resulted in a decreased photosynthetic rate due to the change in leaf submicroscopic structure, indicating the significance of IbmiR319-targeted in leaf anatomical morphology. A systematic analyzation on the characterization of the together with the primary functions in leaf anatomical morphology were conducted to afford a basis for further study of the / module in association with leaf anatomical morphology in sweet potato.
