DND1 and infection: glycinea. In addition, the dnd1 mutant showed reduced growth, a constitutively elevated level of expression of the PR1 gene, HR-like spontaneous lesions without pathogen infection, and resistance to unrelated pathogens including H. parasitica, Botrytis cinerea (Clough et al. 2000) and Pectobacterium carotovorum (the bacterial agent causing soft rot disease on Korean cabbage, Ahn 2007).
