Figure 3.

Relationship between magnetic particle morphology and magnetosome gene content. Genes with similar functions are highlighted by the same-coloured background (Supplementary Tables S6 and S7). Greek letters α, η and γ represent Alphaproteobacteria, Candidatus Etaproteobacteria and Gammaproteobacteria classes. MTB strains are shown in groups according to their phylogeny and magnetite crystal morphologies. Strain names in bold and yellow background represent genomes reported here; grey font represents high contamination (>10%). Black solid circles indicate the presence of the corresponding gene; black hollow circles correspond to its absence. Black hollow circles with a red asterisk inside indicate that the gene was not detected possibly due to incomplete genome sequencing. MACGs, magnetosome core genes in MTB system (i.e. mamA, B, E, I, K, M, P and Q). MACGPs, magnetosome genes only conserved in the Pseudomonadota phylum besides the MACGs (i.e. mamH, F, S and T).
