Research Interest

Research themes in the Sanguinet lab focus on factors that modulate growth and development, particularly in response to the environment. We use physiological, developmental, genetic and genomics approaches to study plant root development and architecture in models such as Arabidopsis thaliana and Brachypodium distachyon as well as crops such as pennycress, wheat and rice. Through characterization and analysis of mutants and natural populations, we hope to gain insight into the quantitative and qualitative control of root development in addition to studying genome-wide responses to abiotic stresses such as cold and drought.
