Paper Title
The Application of Plant Growth Promoting Rhizobacteria Suppressed Turnip Mosaic Virus (TuMV) Infection on Mustard Green (Brassica juncea L.) Plants

Abstract
In this study the use of Plant Growth Promoting Rhizobacteria i.e. Pseudomonas fluorescens and Bacillus subtilis was performed to test their benefit on mustard green plant health against TuMV infection. This study was conducted with a randomized block design (RBD) by using 8 treatments and 4 replications. Mustard green plants inoculated with Pseudomonas fluorescens and Bacillus subtilis had longer roots than those without the inoculation of Pseudomonas fluorescens and Bacillus subtilis. In addition, Pseudomonas fluorescens and Bacillus subtilis was also able to reduce the incubation period as well as the disease intensity of TuMV on the mustard green plant. The activity of catalase enzyme and phenol content was elevated in the mustard green plant leaves which were inoculated with PGPR. The results suggested that catalase and phenol content probably play a role in plant defense induced by PGPR on mustard green against the infection of TuMV.
