Thesis Project:

Transcription factors control many cellular processes related to development. Therefore, alterations in the expression of genes encoding transcription factors may be the major source of diversity responsible for phenotypic changes. Transcription factors of the TCP family are plant-specific. Since its first description in 1999, new findings demonstrate the importance of this gene family on the evolution and control of plant development. The Arabidopsis thaliana TCP5 gene is part of the CIN-like (Class II) clade, and its role in leaf development is already described in the literature. We aim to characterize the expression pattern of TCP5 throughout the development of Arabidopsis reproductive organs and perform a comparative analysis of wild-type and tcp5 mutant plants. We also intend to analyze the floral development of transgenic plants overexpressing TCP5 as well as plants with reduced tcp5/tcp13/tcp17 expression. We expect that the results obtained in this study will contribute to a better understanding of the roles of the TCP gene family in plant reproductive development.
