Plant-specific TCP transcription factors play an essential role in plant growth and development. They can regulate leaf curvature, flower symmetry and the synthesis of secondary metabolites. The flavonoids in leaf are one of the main medicinally bioactivate compounds, which have pharmacological and beneficial health effects for humans. In this study, a total of 13 genes were identified in , and 5 of them belonged to PCF subclades () while others belonged to CIN () subclades according to phylogenetic analysis. Numerous -acting elements related to various biotic and abiotic signals were predicted on the promoters by -element analysis, suggesting that the expression of might be co-regulated by multiple signals....

Plant-specific TCP transcription factors play an essential role in plant growth and development. They can regulate leaf curvature, flower symmetry and the synthesis of secondary metabolites. The flavonoids in leaf are one of the main medicinally bioactivate compounds, which have pharmacological and beneficial health effects for humans. In this study, a total of 13 genes were identified in , and 5 of them belonged to PCF subclades () while others belonged to CIN () subclades according to phylogenetic analysis. Numerous -acting elements related to various biotic and abiotic signals were predicted on the promoters by -element analysis, suggesting that the expression of might be co-regulated by multiple signals. Transcript abundance analysis exhibited that most of responded to multiple phytohormones. Among them, the relative expression levels of , and were found to be significantly influenced by exogenous ABA, SA and MeJA application. In addition, a total of 126 miRNAs were predicted to target 9 (including ). The correlation analysis between the expression level of and the flavonoid contents showed that might involve in flavonoid biosynthesis in . In short, this study mainly provided a theoretical foundation for better understanding the potential function of in .
