Several studies involving the TCP family have been carried out in the last two decades since the first members were discovered and the family was defined. The domain that names the family was well characterized and we know that the protein is a transcription factor that forms a non-canonical bHLH type structure capable of binding to the DNA molecule and promoting interactions between proteins. In recent years it has become clear that members of this family have a key role in the integration of several endogenous and exogenous signals for the control of various aspects of plant development, mainly in the establishment of plant architecture through the control of branching and the transition to reproduction, therefore, being a gene family with great economic potential and possible an important role on the evolution of angiosperms.
