Abstract

Endophytic bacteria reside within plant hosts without causing disease symptoms. Bacterial endophytes promote plant growth and yield, suppress pathogens, may help to remove contaminants, solubilize phosphate, or contribute assimilable nitrogen to plants. The aim of this study were to obtain indigenous endophytic bacterial isolates, which have the ability to control bacterial pustule cause by Xanthomonas axonopodis pv. glycines and to increase growth and yield of soybean. The bacterial endophyte isolates were introduced as seed treatment (108 cfu/ml) and soil drench on 3 weeks old soybean seedling. Xanthomonas axonopodis pv. glycines were inoculated on one month old of soybean by pricking leaf methodes. The effect of bacterial endophyte on disease incidence, disease severity, plant growth and yield of soybean were evaluated. We have found two selected bacterial endophyte isolates from soybean’s rhizosphere (St4E1.1 and St1E1.1.), with the ability to control bacterial pustule and to increase growth and yield of soybean.Key words: bacterial endophyte, bacterial pustule, in planta technique, soybean

Abstract

Pantoea stewartii subsp. stewartii is the pathogen causing stewart’s wilt disease in maize. The occurrence of the disease was recently reported in Indonesia with limited information. Research was conducted to characterize several isolates of P. stewartii subsp. stewartii isolated from maize plants collected from 6 districts in West Sumatra. Leaves showing yellow stripes symptoms along the vein was ground and suspeneded then the bacteria was isolated and incubated for 3 × 24 h at room temperature in nutrient glucose agar (NGA). Pure bacterial colonies gained from this medium was used for characterization. Assessment of bacterial characters was conducted based on morphological assay, physiological assay, biological assay (hypersensitivity, and pathogenicity) followed by polymerase chain reaction (PCR)-based identification. Unique characters of the family Enterobacteriaceae was observed on 7 isolates based on morphological and physiological characters, and only 4 isolates (PR1, PP, ST1, LA) gave positive reaction on hypersensitivity and pathogenicity test. Further molecular identification confirmed 3 out of 7 isolates had high homology to Pantoea stewartii, i.e. Pantoea stewartii strain R1-104, R1-132, and ATCC 29923 for isolates LA, PR1, and PR2, respectively.

Abstract

Two isolates of bacterial endophyte from soybean root were found to be effective to control bacterial pustule caused by Xanthomonas axonopodis pv. glycines. Formulation of the bacterial isolates is required to maintain the effectivity of this bacterial isolates during storage, transportation and application. The aim of this research was to obtain the best carrier for formulation to maintain the effectivity of bacterial endophyte in storage to control bacterial pustule on soybean. Three kind of carrier agent was evaluated for formulation of bacterial endophyte i.e. peat soil, tapioca flour and coconut water + 1% palm oil. Each carrier agent was combined with 5 treatment of storage time i.e. 0, 1, 3, 5 and 7 weeks. Soybean plants was inoculated by. X. axonopodis pv. glycines 2 weeks after planting by rubbing bacterial suspension (106 cel mL-1) on lower surface of leaves. The results showed that all formulas of bacterial endophyte were able to suppress the bacterial pustule on soybean. The best formulations were bacterial endophyte in peat soil stored for 1 and 7 weeks (effectivity rate 79.85% and 77.02%) and coconut water + palm oil and storaged for 3 weeks (effectivity rate 77.46%).
