Research Summary

Our group is discovering plant genes of which functions are linked to quantitative improvements in plants and those with new functions for minimizing the effects of the environmental stresses to achieve maximum productivity. Other targets of research include not only genes that respond to environmental changes and stimuli and adaptation but also genes involved in photosynthesis and productions of useful metabolites. Our group explores key genes involved in improved productivity and abiotic stress tolerance based on genomics including transcriptome and metabolome analyses, and are analyzing regulatory factors and signaling factors involved in the control of gene expression in response to abiotic environmental stresses. We also explore genes involved in metabolic regulation for the improvement plant productivity.
