Linking morphology, genome, and metabolic activity of uncultured magnetotactic Nitrospirota at the single-cell level.

Background: Magnetotactic bacteria (MTB) are a unique group of microorganisms that sense and navigate through the geomagnetic field by biomineralizing magnetic nanoparticles. MTB from the phylum Nitrospirota (previously known as Nitrospirae) thrive in diverse aquatic ecosystems. They are of great interest due to their production of hundreds of magnetite (FeO) magnetosome nanoparticles per cell, which far exceeds that of other MTB.

MagCluster: a Tool for Identification, Annotation, and Visualization of Magnetosome Gene Clusters.

Magnetosome gene clusters (MGCs), which are responsible for magnetosome biosynthesis and organization in magnetotactic bacteria (MTB), are the key to deciphering the mechanisms and evolutionary origin of magnetoreception, organelle biogenesis, and intracellular biomineralization in bacteria. Here, we report the development of MagCluster, a Python stand-alone tool for efficient exploration of MGCs from large-scale (meta)genomic data.

Two Metagenome-Assembled Genome Sequences of Magnetotactic Bacteria in the Order .

Magnetotactic bacteria represent a valuable model system for the study of microbial biomineralization and magnetotaxis. Here, we report two metagenome-assembled genome sequences of uncultivated magnetotactic bacteria belonging to the order These genomes contain nearly complete magnetosome gene clusters responsible for magnetosome biomineralization.
