The TCP (Teosinte branched1/Cincinnata/proliferating cell factor) family gene is a kind of plant specific transcription factor, which plays a significant role in regulating plant growth and development. In this study, 18 TCP genes were identified from the tree peony transcriptome data, the molecular weight was between 18 978.32 and 51 789.56 Da, the isoelectric points was between 5.81 and 9.45, and the subcellular localization prediction of TCP family members was in the nucleus. The classification of conserved amino acids in the tree peony TCP domain was similar to that of Arabidopsis thaliana. Phylogenetic analysis showed that the TCP proteins of tree peony were divided into two categories, Class Ⅰ contained 10 TCP members, and Class Ⅱ contained 8 TCP members. MEME analysis results showed that 15 conserved domains were found in the tree peony TCP protein, Motif 1 was the TCP domain, and was found in all TCP members. Meanwhile, the transcription level of the tree peony TCP genes in bud, leaf, petal, piebaldness, stamen, pistil and seed were analyzed. This article systematically analyzed the tree peony TCP family genes, which provided a scientific basis for further research on functional genes and molecular breeding in tree peony.
