Genetic factors influencing root morphology of Brassicaceae species in response to nitrogen availability


Abstract : Modifying root architecture to capture nutrients more efficiently may represent a sustainable solution to maintain crop productivity whilst reducing fertilizer input. The goal of our research is to first discover the physiological and molecular mechanisms that underpin Nitrogen Use Efficiency (NUE) in the model species Arabidopsis and then to exploit this knowledge to improve closely related Brassica crops using a model-to-crop framework. Understanding how lateral roots are initiated and how they emerge from the parent root is vitally important for improving crop yields. This holds particularly true for the influence of nitrogen (in particular nitrate species) supply on root architecture. We are trying to gain better knowledge about mechanisms of lateral root growth stimulation or repression by nitrate availability. Forward genetic dissections and natural screens are currently used to identify key genes that shape root system architecture, in order to eventually draw strategies to improve nutrient uptake. This is a project description but not a PhD grant offer.
