Characterization and purification of a phytotoxin produced by Fusarium solani, the causal agent of soybean sudden death syndrome.

A phytotoxic polypeptide identified in culture filtrates of Fusarium solani, the causal agent of soybean sudden death syndrome, was heat unstable, negatively charged, absorbed by 10% charcoal, and destroyed by proteinase K. Purification of the phytotoxin was achieved by Sephadex G-50 gel filtration chromatography followed by ion exchange chromatography on a DE-52 column.  The purified protein caused browning of soybean calli, necrosis on detached soybean cotyledons and leaves, and yellowing, curling and drying of attached soybean cotyledons and leaves.
