Distribution of magnetosome chain (MC) partitioning. TEM micrographs of (a) wildtype (WT) and (b) mamK D161A cells displaying MC partitioning during cell division. Scale bars: 1 μm. c Scheme illustrating putative partitioning scenarios during MC length quantification. d Quantification of the partitioned MC length to be inherited by future daughter cells as determined by TEM for the WT (n = 95) and mamK D161A (n = 64) strains. Cells were incubated under 21 % oxygen for 5 h to suppress de novo magnetosome synthesis. e Cumulative distribution of partitioned MC length data for the WT (n = 95) and mamK D161A (n = 64) strains
