Greg Mellers joined the lab as a graduate student in 2013 following a Natural Sciences degree at the University of Cambridge and a Master's degree in Systems Biology. He is a participant in the BBSRC doctoral training programme. His research focuses on the evolution and development of petal spots in the Angiosperms using Gorteria diffusa as a model system. Genes coding for transcription factors within the R2R3 MYB family have shown roles in both anthocyanin production and epidermal elaboration. Hence, this family is the major focus of his work. Comparative expression analyses (ΔCt qPCR) and heterologous expression studies (Nicotiana tabacum) are being undertaken to determine the molecular regulation of spot formation. Genotyping by Sequencing (GBS) is also being used to acquire high SNP coverage in an attempt to understand the relationship between different ‘morphotypes’ of the species (shown to the right). It is hoped that through these diverse techniques a hypothetical model for spot formation may be found and subsequently perturbed for validation.
