Phytotoxic Nep1-like proteins from the necrotrophic fungus Botrytis cinerea associate with membranes and the nucleus of plant cells.
A working theory is that the fungus is undergoing genetic changes enabling it to rapidly shift from that state to its necrotrophic state [surviving on dead tissue].
Pathways involving MeJA and ET are considered to be mainly effective against necrotrophic pathogens, insects, and wounding (Kunkel and Brooks, 2002).
Plant fungal pathogens especially necrotrophic fungus degrade the structural polymers in plant host cell wall and colonize in the intercellular spaces facilitated by the production of cell wall degrading enzymes (CWDEs) such as cellulase, and polygalacturonase.
Botrytis cinerea, a necrotrophic fungus, produces enzymes (Lactase) that oxidize phenolic compounds, resulting in premature browning in white wines and color degradation in red wines.
