From: Genomic insights to SAR86, an abundant and uncultivated marine bacterial lineage
SAR86 genome and population diversity of carbon assimilation. (a) Alignments of orthologs regions of the SAR86A and B genomes are shown to scale. Pink lines join the orthologs from each genome. The small green ‘genes’ and connecting green lines indicate the position of the non-coding RNA found in metatranscriptomic datasets. An alignment of this small RNA is shown in Supplementary Figure S5. (b) The abundances of the genes found in both genomes (glycolysis or glucose uptake) or just the SAR86B genome across 73 GOS metagenomes. The shared genes are clearly conserved, yet many genomes in natural populations lack the oxidative arm of the pentose phosphate pathway or the genes involved in pyruvate metabolism found in only SAR86B. The units on the axes are the number of reciprocal best BLAST hits to either 107 core genes (x axis) or the genes shown in the left panel (y axis), followed by normalization for the number of genes in that category.
