In halophytes from the coast of the Kandalaksha Bay of the White Sea, the occurrence and content of metabolites of the mycotoxin group were studied by enzyme immunoassay. Typical metabolites were emodin, alternariol, mycophenolic acid, while T-2 toxin and roridin A were not found. A number of features of the metabolic profile of plants was revealed — the presence of fumonisins (); ochratoxin A, citrinin, diacetoxyscirpenol, deoxynivalenol, zearalenone and PR-toxin (); nitrogen-containing compounds — cyclopiazonic acid and ergot alkaloids (Cochlearia groenlandica, , , ); a significant content of emodin and sterigmatocystin (Honekenya pepioides); rare cases of contamination (). For , and selected in different years from remote ecotopes, a significant variability in the contents of emodin and alternariol has been established. The possible participation of their endophytes in responses of plants to changes in habitat conditions is discussed.
Burkin et al. (Wed,) studied this question.
