Fig. 2: A comparison of genomic characteristics among ancient planthopper symbionts Sulcia and Vidania, relative to other bacteria and organelles.

A In terms of size and gene content, Fulgoromorpha symbiont genomes (red) fall among the very smallest known for insect-symbiotic bacteria (pink), which themselves are among the smallest bacterial genomes overall (other, non–insect-symbiotic bacteria shown in blue). Cellular organelles—mitochondria (orange) and chloroplasts (green)—are shown for reference. The data underlying the scatterplot represent 66949 complete genomes downloaded from NCBI in April 2024, listed in Source Data. B In terms of size and GC contents, the newly reconstructed genomes of planthopper-associated Sulcia tend to be relatively consistent, whereas Vidania genomes represent a much broader range on both scales. Source data are provided as a Source Data file.
