Title: Evidence of a Gene-for-Gene Relationship in the<i>Oryza sativa-Magnaporthe grisea</i>Pathosystem
Abstract: A cross was made between two field isolates of Magnaporthe grisea pathogenic to rice. Full-sib crosses between F 1 ascospores, followed by backcrosses to the female fertile parent GUY 11, produced perithecia fertile enough for tetrad isolation. Genetic analysis of the pathogen revealed that avirulence to the rice cultivar Pi-n o 4 is controlled by one gene (Avr1-Pi-n o 4) unlinked to the gene MATI-1, which is responsible for mating type. Additionally, resistance of Pi-n o 4 was found to be controlled by one gene. Thus, existence of a gene-for-gene relationship was shown for the pathosystem Oryza sativa-M. grisea
