Abstract/Description: | In the present study, efforts were made to understand the resistant mechanism mediated by biocontrol agents in tomato plants against Helicoverpa armigera. Defense enzymes viz. peroxidase, phenylalanine ammonia-lyase, polyphenol oxidase, catalase, super oxide dismutase were analysed by Polyacrylamide Gel Electrophoresis (PAGE). SDS-PAGE was used for studying the protein profile as well as Western Blotting for chitinase. Application of a mixture of B. subtilis and B. bassiana significantly enhanced the defense-related enzymes. The results showed higher induction of PO and PPO in plants treated with combination of B2 + EPC8 than the plants treated with individual strains, chemical and untreated controls. In addition, B2 + EPC8 combination showed a greater accumulation of CAT and SOD which plays a vital role in induced resistance. Western blot analysis of chitinase revealed the induction chitinase isoform (29 KDa) in tomato plants treated with a mixture of B2 + EPC8 strains against fruit borer pest. The combined application of bioformulation also increased the accumulation of phenol as well as the defence related proteins in tomato plants. Moreover, the outcome of the present study has a potential to be used for sustainable and eco-friendly tomato production. |
