Clustering arrangements of genes encoding COG0354 and functional complementation of an E. coli COG0354 deletant by an Arabidopsis COG0354. (A) Clustering of COG0354 genes with Fe/S-related genes. Blue, COG0354; red, Fe/S proteins; rose, proteins in same complex or pathway as Fe/S proteins; turquoise, Fe/S cluster assembly proteins. Rx, Rubrobacter xylanophilus; Sm, Stenotrophomonas maltophilia; Pu, Pelagibacter ubique. (B) Growth of an E. coli COG0354 (ygfZ) deletant harboring plasmid-borne E. coli ygfZ, Arabidopsis mitochondrial COG0354, or vector alone on LB medium or LB plus the oxidative stress agent plumbagin (OX) (30 μM), arabinose (0.02% w/v), and appropriate antibiotics.
