ABSTRACT Frequent spontaneous loss of the magnetic phenotype was observed in stationary-phase cultures of the magnetotactic bacterium Magnetospirillum gryphiswaldense MSR-1. A nonmagnetic mutant, designated strain MSR-1B, was isolated and characterized. The mutant lacked any structures resembling magnetosome crystals as well as internal membrane vesicles. The growth of strain MSR-1B was impaired under all growth conditions tested, and the uptake and accumulation of iron were drastically reduced… Expand
A Hypervariable 130-Kilobase Genomic Region of Magnetospirillum gryphiswaldense Comprises a Magnetosome Island Which Undergoes Frequent Rearrangements during Stationary Growth
TLDR
The data suggest that the genomic MAI undergoes frequent transposition events, which lead to subsequent deletion by homologous recombination under physiological stress conditions, which can be interpreted in terms of adaptation to physiological stress and might contribute to the genetic plasticity and mobilization of the magnetosome island. Expand
Frequent Mutations within the Genomic Magnetosome Island of Magnetospirillum gryphiswaldense Are Mediated by RecA
TLDR
It is shown that a RecA-deficient strain of Magnetospirillum gryphiswaldense (IK-1) no longer exhibits genetic instability of magnetosome formation, and increased genetic stability could make strain IK-1 a useful tool for the expression of genes and further genetic engineering, as well as for biotechnological production of bacterial magnetosomes. Expand
Disruption of a fur-like gene inhibits magnetosome formation in Magnetospirillum gryphiswaldense MSR-1.
TLDR
Data suggest that Fur protein may possess a novel function in magnetic bacteria and be able to tolerate 1 mM H2O2 at 10-fold higher level than wild-type. Expand
Functional Analysis of the Magnetosome Island in Magnetospirillum gryphiswaldense: The mamAB Operon Is Sufficient for Magnetite Biomineralization
TLDR
A comprehensive bioinformatic, proteomic and genetic analysis of the MAI in Magnetospirillum gryphiswaldense demonstrates that the entire region is dispensable for growth, and the majority of MAI genes have no detectable function in magnetosome formation and could be eliminated without any effect. Expand
Complete genome sequence of the facultative anaerobic magnetotactic bacterium Magnetospirillum sp. strain AMB-1.
TLDR
This comprehensive genome analysis will enable resolution of the mechanisms of magnetosome formation and provide a template to determine how magnetic bacteria maintain a species-specific, nano-sized, magnetic single domain and paramagnetic morphology. Expand
Magnetospirillum magneticum AMB-1 peroxiredoxins contribute to the aerotolerance and genetic stability of the genomic magnetosome island.
TLDR
Data suggest that the thiol-peroxidases identified act as key antioxidants in magnetotactic bacteria and, as a result, contribute to maintaining their capacity to synthesize magnetosome by shielding the genetic stability of the genomic MAI in adaptation to constant physiological change and stress. Expand
Homologous and heterologous expression of magnetosome operons from Magnetospirillum gryphiswaldense
TLDR
It is demonstrated that the five previously uncharacterized genes of the mms6 operon have crucial functions in the regulation of magnetosome biomineralization that partially overlap with MamF and other proteins encoded by the adjacent mamGFDC operon. Expand
Identification and elimination of genomic regions irrelevant for magnetosome biosynthesis by large-scale deletion in Magnetospirillum gryphiswaldense
TLDR
It is demonstrated that an allelic replacement method based on homologous recombination can be applied for large-scale genome editing in M. gryphiswaldense and further delineate the genetic complement for magnetosome biosynthesis and will be useful for future large- scale genome editing and genetic engineering of magnetosom biosynthesis. Expand
Genomic study of a novel magnetotactic Alphaproteobacteria uncovers the multiple ancestry of magnetotaxis
TLDR
Comparing the morphology and the whole genome shotgun sequence of this MTB with those of closer relatives brought further evidence that the apparent vertical ancestry of magnetosome genes suggested by previous studies within Alphaproteobacteria hides a more complex evolutionary history involving horizontal gene transfers and/or duplication events before and after the emergence of Magnetospirillum, Magnetovibrio and Magnetospira genera.
