Advances in the Characterization of the Mechanism Underlying Bacterial Canker Development and Tomato Plant Resistance

Bacterial canker caused by the Gram-positive actinobacterium Clavibacter michiganensis is one of most serious bacterial diseases tomatoes, responsible for 10–100% yield losses worldwide. The pathogen can systemically colonize tomato vascular bundles, leading to wilting, cankers, bird’s eye lesions, and plant death. Bactericidal agents are insufficient managing this disease, because rapidly migrate through system plants induce systemic symptoms. Therefore, use resistant cultivars necessary controlling disease. We herein summarize pathogenicity C. in molecular basis pathogenesis. Moreover, advances characterization resistance tomatoes introduced, status genetics-based research described. Finally, we propose potential future on resistance. More specifically, there a need thorough analysis host–pathogen interaction, accelerated identification annotation genes mechanisms, diversification resources or exhibiting broad-spectrum disease resistance, production novel effective control prevention. This review provides researchers with relevant information breeding cankers.
