Differential contribution of Clavibacter michiganensis ssp. michiganensis virulence factors to systemic and local infection in tomato.

ABSTRACT: Clavibacter michiganensis ssp. michiganensis (Cmm) causes substantial economic losses in tomato production worldwide. The disease symptoms observed in plants infected systemically by Cmm are wilting and canker on the stem, whereas blister-like spots develop in locally infected leaves. A wide repertoire of serine proteases and cell wall-degrading enzymes has been implicated in the development of wilt and canker symptoms. However, virulence factors involved in the formation of blister-like spots, which play an important role in Cmm secondary spread in tomato nurseries, are largely unknown. Here, we demonstrate that Cmm virulence factors play different roles during blister formation relative to wilting. Inoculation with a green fluorescent protein (GFP)-labelled Cmm382 indicates that penetrat
