Abstract
TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) protein family is a large transcriptional regulator family in plant, which are important in various plant processes including leaf development, flower symmetry, shoot branching, and senescence. In this study, phylogenetic relationship, chromosome location, conservative domain structure and expression profiles in flower and fruit development of the TCP TFs family in woodland strawberry (Fragaria vesca) was performed. In total, 18 TCP members were identified in F. vesca. These 18 genes are evenly distributed on chromosome 4 to 7. All of them had highly conserved domain sequences through analyzing the functional domain of the 18 members. The TCP members were divided into TCP-C and TCP-P according to the difference of domain and phylogenetic analysis. Phylogenetic tree analysis showed that F. vesca TCP proteins were grouped into two subfamilies, class I and class II. Expression profile analysis of the FvTCP family, which is related to the flower and fruit development from the project site, indicated that 13 members were related to flower development and five members were related to fruit development. These results suggested the important role of FvTCP proteins in fruit and flower development.
