| Description |
Tobacco Mosaic Tobamovirus (TMV) is one of many important viruses infecting Solanaceous plants including hotpepper in Indonesia. To accomplish and improve the effectiveness of virus management, we used root-colonizing bacteria(rhizobacteria) isolated from healthy hot pepper. Eight rhizobacteria isolates were selected and their capacity in enhancingplant growth and inducing systemic resistance (ISR) against TMV in greenhouse trials were evaluated. Therhizobacteria was applied as seed treatment and soil drench. Bacterized-seedling showed a better growth vigor, fitness anda milder symptom than non-bacterized control plants. The protective effect of rhizobacteria was more pronounced afterchallenging inoculation by TMV, especially for plants treated by isolates I-6, I-16, and I-35. However, TMV accumulationwas slightly affected by bacterial treatment. The rhizobacteria might improved ISR by increasing peroxidase enzymeactivity but this depends on the species. Based on whole results, isolate I-35 was the potential plant growth promotionrhizobacteria (PGPR). The I-35 was identified as Bacillus cereus based on morphological characteristics and nucleotidesequences of 16S r-RNA.
