  • Title: Bacterial type two secretion system secreted proteins: double-edged swords for plant pathogens.
    Author: Jha G, Rajeshwari R, Sonti RV.
    Journal: Mol Plant Microbe Interact; 2005 Sep; 18(9):891-8. PubMed ID: 16167759.
    Abstract:
    The type two secretion system (T2S) is important for virulence of a number of gram-negative bacterial plant pathogens. Most of the T2S-secreted proteins that have been characterized to date are involved in degrading different components of plant cell walls. Functional redundancy appears to exist among T2S-secreted proteins because significant effects on virulence are observed only in strains in which multiple secreted proteins are mutated. Several T2S-secreted proteins have been shown to induce plant defense responses, including hypersensitive response-like reactions. Bacterial pathogens can suppress these defense responses, and recent results indicate that suppression is mediated through the type three secretion system.
