Purified chestnut cystatin inhibited the growth of the phytopathogenic fungi Botrytis cinerea, Colletotrichum graminicola, and Septoria nodorum, but not that of the saprophyte Trichoderma viride. Furthermore, the cystatin strongly affected the protease activity of B. cinerea but had no effect on the protease activity of T. viride. These results suggest that chestnut cystatin contributes to plant defense against phytopathogenic fungi.
