Furthermore, silencing the tomato DND1 ortholog in cv Moneymaker also resulted in reduced susceptibility of tomato to B. cinerea. Based on the microscopic observations of the infection process of B. cinerea on DND1 well-silenced tomato and potato plants, we discuss here the potential mechanisms by which the silencing of the DND1 gene confers reduced susceptibility to B. cinerea. Here, DND1 is linked to infection.
