Abstract
Addition of fruit cell wall extracts from two muskmelon cultivars into liquid media affected mycotoxin production by a strain of Myrothecium roridum pathogenic to muskmelon. Cell wall extracts from a susceptible cultivar (‘Iroquois’) significantly increased toxin production while cell wall extracts from a resistant cultivar (‘Hales Best’) significantly inhibited toxin production. Media containing 0.1 or 1.0 mg ml−1 stimulated toxin production more than media containing 10 or 100 mg ml−1 of cell wall extracts. Previous studies in our laboratory suggest that roridin E may be involved in virulence or pathogenicity of M. roridum; the present study indicates that cell wall polysaccharides as well as other materials present in cell wall preparations from susceptible host tissue provide a better substrate for toxin production than cell wall preparation from resistant host tissue.
