| methylobacterium salsuginis sp. nov., isolated from seawater. | three pink-pigmented, facultatively methylotrophic strains, designated mp1, mp2 and mr(t), were isolated from seawater from southern china and characterized. analysis of their complete 16s rrna gene sequences revealed that they constituted three separate phylogenetic groups, showing the highest levels of similarity with respect to some members of the genus methylobacterium. pcr amplification also showed the gene coding for the alpha-subunit of methanol dehydrogenase (mxaf) to be present in all s ... | 2007 | 17684240 |
| metal tolerating methylotrophic bacteria reduces nickel and cadmium toxicity and promotes plant growth of tomato (lycopersicon esculentum l). | inoculation of plants with microorganisms may reduce the toxicity of heavy metals to plants in contaminated soils. in this study, we have shown that the plant growth promoting bacteria methylobacterium oryzae strain cbmb20 and burkholderia sp. strain cbmb40 from rice reduce the toxicity of ni and cd in tomato and promote plant growth under gnotobiotic and pot culture experiments. the bacterial strains bound considerable amounts of ni(ii) and cd(ii) in their growing and resting cells and showed g ... | 2007 | 17512031 |

| aggregation of selected plant growth promoting methylobacterium strains: role of cell surface components and hydrophobicity. | the bacterial cell surface plays a major role in the bacterial aggregation that in turn plays a positive role in affecting the bacterial dispersion and survival in soil and their ability to adhere to plant surfaces. plant growth-promoting methylobacterium strains, methylobacterium goesingense cbmb5, methylobacterium sp. cbmb12, methylobacterium oryzae cbmb20, methylobacterium fujisawaense cbmb37, m. oryzae cbmb110 and methylobacterium suomiense cbmb120 were evaluated for aggregation efficiency. ... | 2013 | 23354325 |
| regulation of root development in arabidopsis thaliana by phytohormone-secreting epiphytic methylobacteria. | in numerous experimental studies, seedlings of the model dicot arabidopsis thaliana have been raised on sterile mineral salt agar. however, under natural conditions, no plant has ever grown in an environment without bacteria. here, we document that germ-free (gnotobiotic) seedlings, raised on mineral salt agar without sucrose, develop very short root hairs. in the presence of a soil extract that contains naturally occurring microbes, root hair elongation is promoted; this effect can be mimicked ... | 2017 | 28054231 |
