The Melanin Biosynthesis Genes of Alternaria alternata Can Restore Pathogenicity of the Melanin-Deficient Mutants of Magnaporthe grisea

Molecular Plant-Microbe Interactions, 1997
The phytopathogenic fungi Magnaporthe grisea and Alternaria alternata produce melanin via the polyketide biosynthesis, and both fungi form melanized colonies. However, the site of melanin deposition and the role of melanin in pathogenicity differ between
