Interpretive Summary:

Previous studies showed that field samples of rice from plants with Fusarium sheath rot diseases contained fumonisins, which are important toxins that can affect animal and human health. Cultures of F. proliferatum established from these samples produced fumonisins when cultured on rice. They also produced other toxins, including moniliformin and beauvericin, which were not found in naturally-infected field samples of rice. It is not known why moniliformin and beauvericin were not found in field samples. There may be mechanisms by which viable rice kernels suppress synthesis of moniliformin and beauvericin by F. proliferatum, that are not operative in autoclaved rice cultures. A better understanding of the mechanisms by which mycotoxin production is controlled in Fusarium sp. may lead to methods to control these compounds in food and feed.
