We are analyzing novel epigenetic, RNA and peptide regulation mechanisms in environmental stress adaptation and acclimation by cutting-edge genomic approaches. We aim to develop useful plant resources, such as stress-tolerant plants by use of chemical compounds etc. We are analyzing regulatory networks of tuber root development in cassava by integrated omics analyses and aim to develop useful cassava plants, such as improved plant productivity.
