Plants have evolved strategies of stimulating and supporting specific groups of antagonistic microorganisms in the rhizosphere as a defense against diseases caused by soilborne plant pathogens owing to a lack of genetic resistance to some of the most common and widespread soilborne pathogens. Some of the best examples of natural microbial defense of plant roots occur in disease suppressive soil...

plant growth-promoting rhizobacteria (pgpr) is an alternative to chemical pesticides against harmful microorganisms especially soil-borne diseases. rhizoctonia solani is one of the most important soil-borne fungal pathogens that causes serious damages to important crops. in this study, to screen successful pseudomonas bacterial isolates, the inhibition of pathogen growth was evaluated in-vitro....

Kwak, Y.-S., Bakker, P. A. H. M., Glandorf, D. C. M., Rice, J. T., Paulitz, T. C., and Weller, D. M. 2009. Diversity, virulence, and 2,4-diacetylphloroglucinol sensitivity of Gaeumannomyces graminis var. tritici isolates from Washington State. Phytopathology 99:472-479. We determined whether isolates of the take-all pathogen Gaeumannomyces graminis var. tritici become less sensitive to 2,4-diac...
