Evidence of a Gene-for-Gene Relationship in the <i>Oryza sativa</i> - <i>Magnaporthe grisea</i> Pathosystem
10 Sept 2007
Abstract excerpt
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 GUY11, produced perithecia fertile enough for tetrad isolation. Genetic analysis of the pathogen revealed that avirulence to the rice cultivar Pi-n°4 is controlled by one gene ( Avr1-Pi-n°4) unlinked to the gene MAT1-1, which is...
