Asparagine germination

Amino acids mixtures stimulate aflatoxin biosynthesis, particularly asparagine and aspartic acid. Proline has been reported to stimulate conidial germination in a culture that was probably A. parasiticus, although reported as A. flavus (14). These investigators reported the greatest toxin formation with a mixture of amino acids followed by a mixture of proline plus glutamate or proline plus aspartate. The effect in the latter instances may have been due to the effect on conidial germination rather than a direct effect on aflatoxin biosynthesis.

The cotyledons of germinating seeds have proved to be a major source of asparagine synthetase activity and the enzyme has been studied in lupins (Rognes, 1975,1980 Lea and Fowden, 1975X soybean (Streeter, 1973), cotton...
