Physical Mapping of the Magnaporthe grisea AVR1-MARA Locus Reveals the Virulent Allele Contains Two Deletions
The avirulence genes that have been identified in Heater Timer Magna-porthe grisea exhibit varying degrees of stability in infection assays.AVR1-MARA is considered one of the stable avirulence genes.In an effort to understand this stability, we analyzed the AVR1-MARA locus by physical mapping and chromosome walking.By walking toward AVR1-MARA from
