The avirulence genes that have been identified in 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. https://parisnaturalfoodes.shop/product-category/vegan-protein-choco/
