The population of the earth is rapidly increasing, setting food security one of the major issues in the world, especially in developing countries. Additionally, climate changes also put a great burden on food production. Environmental stresses, such as drought, high salinity, soil erosion and pollutants are the factors affecting yield and stability of crop production, thereby threatening sustainable agriculture. Our unit has interest in (i) studying the roles of plant growth regulators and their interactions in abiotic stress responses, as well as (ii) translational genomics aiming to enhance crop productivity under adverse environmental stress conditions.
