Secondary Metabolites of Micromycetes in Plants of the Family Fabaceae, Genus Trifolium

Аннотация

The component composition and content of mycotoxins in perennial grasses of five species of the genus Trifolium, selected from natural biocenoses in different periods of vegetation, were studied. In the terrestrial parts of plants, the permanent presence of alternariol, cyclopiazonic acid, and emodin was shown. It was noted that differences in contamination are most clearly expressed in meadow clover Trifolium pratense L. and white clover Trifolium repens L., while alsike clover Trifolium hybridum L. occupies an intermediate position. It was found that zigzag clover Trifolium medium L. and mountain clover Trifolium montanum L., morphologically close to meadow clover, practically did not differ in the composition of toxic metabolites. The ways of formation of metabolic equilibrium in plants with participation of microscopic fungi are discussed.
