Outline of Final Research Achievements |
Strong reciprocal natural selection between a host plant and a pathogen leaves DNA signatures on the genomes of respective organisms. By employing whole genome sequencing and detecting DNA signatures of selection, we succeeded in isolating two rice resistance (R-) genes (Pia and Pii) and three Magnaporthe oryzae avirulence effector (AVR) genes (AVR-Pia, AVR-Pii, AVR-Pik). Molecular interactions between rice R-protein Pik and Magnaporthe AVR-Pik revealed that their genes are coevolving. We also have developed a series of methods including MutMap and QTL-seq to quickly detect selection signature by whole genome resequencing.
