Abstract
Bacillus amyloliquefaciens strain KPS46 has been previously reported to promote plant growth and protect soybean plants from multiple diseases including bacterial pustule caused by Xanthomonas axonopodis pv. glycines . Greenhouse assays were evaluated for its efficient induction of defense-related enzymes in tested plants. Soybean seeds treated with strain KPS46 at sowing and 14 days later challenged the seedlings with bacterial pustule pathogen had few necrotic lesions and reduced disease severity as compared with soybean plants not bacterized with KPS46. The increase in production of total phenol, phenylalanine ammonia lyase, peroxidases and 1,3-β-glucanases were expressed at higher levels in treatment with KPS46 challenge inoculated with the pathogen as compared with the diseased and control plants. Almost defense-related enzymes detected were found to accumulate in soybean leaf tissues of the co-inoculation at one day and reached maximum at 4th day after pathogen challenge, respectively. The pathogen inoculation alone however, started the accumulation at the 3rd day and drastically decreased at 4th day. These produces appear to be one mechanism of biological control by strain KPS46 and may play a role in plant defense against pathogen infectionKeywords
