Induction of resistance in tomato against cucumber mosaic cucumovirus by plant growth-promoting rhizobacteria
Studies were done to evaluate specific strains of plant growth promoting rhizobacteria (PGPR) for induced resistance against cucumber mosaic cucumovirus (CMV) in tomato. In greenhouse experiments where plants were challenged by mechanical inoculation of CMV, the percentage of symptomatic plants in the most effective PGPR treatments ranged from 32 to 58%, compared with 88 to 98% in the nonbacter...
متن کاملRhizobacteria-Mediated Growth Promotion of Tomato Leads to Protection Against Cucumber mosaic virus.
ABSTRACT We evaluated combinations of two strains of plant growth-promoting rhizobacteria (PGPR) formulated with the carrier chitosan for the ability to induce growth promotion of tomato plants and resistance to infection by Cucumber mosaic virus (CMV). Each PGPR combination included GB03 (Bacillus subtilis) and one of the following PGPR strains: SE34 (B. pumilus), IN937a (B. amyloliquefaciens)...
متن کاملEvaluation of some Plant Growth Promoting Rhizobacteria (PGPR) to Control Pythium aphanidermatum in Cucumber Plants
Twenty isolates of bacteria were successfully isolated from rhizosphere soil samples collected from different plant species growing at various locations in North Jeddah, Saudi Arabia to investigate their effects on Cucumis sativus L. cv. Marketmore growth and damping-off disease caused by Pythium aphanidermatum. The results of dual culture method showed that only three isolates out of twenty, w...
متن کاملPhotoperiod regulates elicitation of growth promotion but not induced resistance by plant growth-promoting rhizobacteria.
For several years, we have noticed that plant growth-promoting rhizobacteria (PGPR), which consistently promote plant growth in greenhouse tests during spring, summer, and fall, fail to elicit plant growth promotion during the midwinter under ambient light conditions. This report tests the hypothesis that photoperiod regulates elicitation of growth promotion and induced systemic resistance (ISR...
متن کاملInduction of systemic resistance by plant growth promoting rhizobacteria in crop plants against pests and diseases
Plant growth promoting rhizobacteria (PGPR) belonging to Pseudomonas spp. are being exploited commercially for plant protection to induce systemic resistance against various pests and diseases. Mixtures of di!erent PGPR strains have resulted in increased e$cacy by inducing systemic resistance against several pathogens attacking the same crop. Seed-treatment with PGPR causes cell wall structural...
