A tale for two roles: Root-secreted methyl ferulate inhibits P. nicotianae and enriches the rhizosphere Bacillus against black shank disease in tobacco.

ABSTRACT:

Background

Root exudates serve as chemical signaling molecules that regulate rhizosphere interactions and control soil-borne diseases. The interactions between plants and the soil microbiome play dynamic and crucial roles in regulating the resistance of plants to biotic stress. However, the specific roles of many root exudates in plant pathogens remain unclear. The root exudate methyl ferulate, a naturally occurring and relatively non-toxic antifungal agent, has been applied to control postharvest pathogens and preserve foodstuffs and has not been used in plant disease control.

Results

This study investigated the role of the root exudate methyl ferulate in controlling tobacco black shank disease. We observed that methyl ferulate was secreted in greater quantities in the toba
