This study, framed in two different phases, studied the plant-growth promotion and the induction of systemic resistance in groundnut by Methylobacterium. Seed imbibition with Methylobacterium sp. increased germination by 19.5% compared with controls. Combined inoculation of Methylobacterium sp. with Rhizobium sp. also significantly increased plant growth,(More)
An aerobic, yellow-pigmented, facultatively methylotrophic, Gram-staining-negative, non-spore-forming bacterium, designated strain Gm-149(T), was isolated from the rhizosphere of cultivated soybean in India. Cells were motile by gliding. The predominant cellular fatty acids were iso-C(15 : 0), summed feature 3 (comprising iso-C(15 : 0) 2-OH and/or C(16 : 1)(More)
Biotic stress like pathogenic infection increases ethylene biosynthesis in plants and ethylene inhibitors are known to alleviate the severity of plant disease incidence. This study aimed to reduce the bacterial spot disease incidence in tomato plants caused by Xanthomonas campestris pv. vesicatoria (XCV) by modulating stress ethylene with(More)
The existence of Methylobacterium as a symbiont with sugarcane and its influence on crop growth at various stages was examined. Pink-pigmented facultative methylotrophic bacteria (PPFMs) strains isolated from different parts of the sugarcane clone Co86032 showed growth on methanol, and were further confirmed based on the mxaF gene encoding the α-subunit of(More)
Two isolates from rhizosphere soil of cotton, designated Gh-67(T) and Gh-48(T), which produced large amounts of extracellular polysaccharide and possessed plant-growth-promoting traits, were characterized phenotypically and genotypically. The strains were Gram-negative and cells were non-motile rods that grew optimally at 28°C and grew between pH 4 and 7.(More)
Two yellow-pigmented, Gram-stain-positive, aerobic, motile, short rod-shaped bacteria were isolated from natural teak tree rhizosphere soil and their taxonomic positions were determined by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strains TG-S248(T) and TG-S240 formed a distinct phyletic line within the genus(More)
Endophytic colonization in rice was induced using rhizobia. Dehusked seeds of rice hybrid, CORH2, were used as explants for induction of calli. MS medium was modified with 2,4-D (2.5 mg l−1) and kinetin (0.2 mg l−1) for callus induction. Well-developed calli were inoculated with Azorhizobium caulinodans strains ORS 571 and AA-SK-5 by means of imbibition.(More)
The potential of bacterial endophytes to improve symbiotic efficiency through synergistic interactions with rhizobia can help to improve nodulation and nitrogen fixation in legume plants. In the present study, we compared the effect of endophytic plant growth-promoting bacteria on nodulation and effective rhizobial symbiosis in soybean. Nodule endophyte(More)
The Janghang smelter in Chungnam, South Korea started in 1936 was subsequently shutdown in 1989 due to heavy metal (loid) pollution concerns in the vicinity. Thus, there is a need for the soil in the area to be remediated to make it usable again especially for agricultural purposes. The present study was conducted to exploit the potential of arsenic(More)
The studies on the biocontrol potential of pink pigmented facultative methylotrophic (PPFM) bacteria other than the genus Methylobacterium are scarce. In the present study, we report three facultative methylotrophic isolates; PPO-1, PPT-1, and PPB-1, respectively, identified as Delftia lacustris, Bacillus subtilis, and Bacillus cereus by 16S rRNA gene(More)
