Molecular mechanisms of defense by rhizobacteria against root disease.

Abstract: Genetic resistance in plants to root diseases is rare, and agriculture depends instead on practices such as crop rotation and soil fumigation to control these diseases. "Induced suppression" is a natural phenomenon whereby a soil due to microbiological changes converts from conducive to suppressive to a soilborne pathogen during prolonged monoculture of the susceptible host. Our studies have focused on the wheat root disease "take-all," caused by the fungus Gaeumannomyces graminis var. tritici, and the role of… Show more

“…Often, antagonistic microorganisms can produce a range of different antimicrobial secondary metabolites, e.g. 2,4-diacetylphloroglucinol (DAPG), pyrrolnitrin, pyoluteorin, phenazines, cyclic lipopeptides and hydrogen cyanide in the case of certain fluorescent pseudomonads (Raaijmakers et al , 2006Picard and Bosco 2008;Cook et al 1995;Weller 2007). Antimicrobial secondary metabolites are also involved in antagonistic effects of fungi such as Trichoderma and Gliocladium (Kubicek et al 2001).…”

“…Cook et al (34) suggested the absence of useful genes in wheat and wheat relatives for resistance to take-all could be due to the protection afforded by the DAPG-producing rhizobacteria enriched by wheat monoculture, thereby relieving selection pressure on the host for evolution of resistance such as has occurred with foliar pathogens. Although rhizobacteria responsible for suppression of root diseases represent another genetic resource for use in breeding crop plants for enhanced resistance to pathogens, their management through the cropping system, e.g., crop monoculture, or their introduction with seeds or other the planting material (35) currently represents the best options for maximizing their benefits.…”

“…Cook et al (1995) postulated that plants have developed an entirely different strategy to defend themselves against soilborne pathogens. This strategy involves the ability of plants to selectively stimulate and support populations of soil and rhizosphere microorganisms that are antagonistic to their pathogens.…”
