FIG. 2.
(A) TEM micrographs of wild-type (I), ΔmamJ (II to VII), and ΔmamJ cells trans-complemented with pAS50 (VIII). Scale bars, 500 nm. (B) Distribution of magnetosome crystal numbers in stationary cultures of wild-type (I) and ΔmamJ (II) cells. Numbers were determined by counting 309 cells by TEM. Insets illustrate the magnetosome distribution to daughter cells during cell division in wild-type and ΔmamJ cells.
