I have a main interest in the plasticity of plants, which enables them to adapt to a wide range of biotic and abiotic circumstances and I study how plants adapt (lateral) root development to salt stress. Because lateral roots are specialized in water and nutrient uptake, they might also be the place where most of the sodium, which is toxic to plants, is taken up. We hypothesize that adapting lateral root development can be favourable for salt tolerance. Our previous research has shown natural variation in root architectural responses to salt. I will continue on this project by investigating the regulation and functionality of differences in root development. Root-expressed auxin biosynthesis genes will be central in this project. For me, this project has the potential to connect the underlying genetics of a physiological process with its function. Eventually, this knowledge will lead to targets for improving crop tolerance to salt stress.
