Fig. 5: Comparison of genomic features of bacteria with extremely small genomes and low GC contents.
From: A human respiratory tract-associated bacterium with an extremely small genome
a Scatter plot based on the genome sizes and GC contents of 9871 bacteria. Orange dots indicate bacteria with host names registered as “Homo sapiens”. IOLA is indicated by a red dot. b COG functional category proportions, hosts, and genome sizes of the host-associated bacteria with small genomes are shown. The 39 bacterial species with the smallest genome size in each genus were selected from 265 host-associated bacteria with genome sizes less than 1.2 Mb. The major clusters based on the heatmap of COG functional category proportions are colored. All information, such as the number of genes in each COG functional category, host names, genome sizes, and ecosystems, was collected from the JGI IMG database (http://img.jgi.doe.gov). The arrows in a show the human-associated bacteria selected in b. The generally known nonhuman vectors or hosts of the human-associated bacteria are shown as gray boxes in “host category”.
