English: HRTEM images of magnetite magnetosomes with highly anisotropic, elongated, pointed habits but different elongation directions. (A) A magnetosome from an unidentified freshwater rod, elongated parallel to [111], with the corresponding selected area electron diffraction (SAED) pattern in the lower left. (B) A composite image of a curved, fts magnetosome from the magnetotactic Nitrospirae strain HSMV-1, elongated parallel to [110], with the corresponding Fourier transform in the lower right. (C) A dts magnetosome form the magnetotactic Deltaproteobacteria strain AV-1, elongated parallel to [001], with the corresponding SAED pattern in the upper left. All three images were obtained with the electron beam parallel to [1–10].
