WebMutants resistant to nikkomycin, an inhibitor of chitin biosynthesis, were isolated after exposure of wild-type spores of the fungus Phycomyces blakesleeanus to N-methyl-N′-nitro-N-nitrosoguanidine. Genetic analysis revealed that nikkomycin resistance was due to mutations in a single gene, chsA. WebChitin is a structural and functional component of the fungal cell wall and also serves as a pathogen-associated molecular pattern (PAMP) that triggers the innate immune responses of host plants. However, no or very little chitin is found in the fungus-like oomycetes.
