Genome-Wide Identification and Characterization of TCP Family Genes Related to Flower and Fruit Development in Woodland Strawberry (Fragaria vesca)

Abstract
Abstract:TCP proteins are plant-specific transcription factors (TFs), which play important roles in various plant processes including leaf development, flower symmetry, shoot branching, and senescence. In this study, the identification and expression analysis of the TCP TFs family in woodland strawberry (Fragaria vesca), including phylogenetic relationship, chromosome location, conservative domain structure and expression profiles in flower and fruit development was performed. A total of 18 TCP members were identified in F. vesca. These 18 genes were distributed on all the chromosomes except chromosome 1, 2. 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 could be divided 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 proteinsin fruit and flower development.
