Major in plant science deals with theories and techniques for the plant production harmonized with nature and agro-ecosystems that are essential for human survival. It also pursues exploration of life phenomena in crop plants at levels from molecular to community through understanding heredity, environment, and their interrelationships, in order to ensure both productivity and quality of crop plants. Education goal is to bring up global talents through teaching and training on (1) breeding novel crop varieties using conventional and molecular tools, (2) understanding the mechanism of plant adaptation to abiotic and biotic stresses, (3) identifying, understanding, and producing new substances in industrial and medicinal plants having specific functions, (4) establishing sustainable agricultural systems by minimizing limiting factors to crop production, and (5) understanding crop responses to global change (GC) and strategies to cope with GC.
