Relationship between gene length and reads detected for cyanomyovirus genes observed in metagenomic databases from three different environments: Sargasso Sea (BATS), N. Pacific (HOT) and Mediterranean Sea (MedDCM). Red circles indicate single copy signature core genes identified in 28 cultured cyanomyovirus genomes. The linear relationship (adjusted r² values are 0.89, 0.95 and 0.94 for BATS, HOT and MedDCM respectively) between gene length and the number of times a gene is found supports the assertion that these genes are core in the wild populations of cyanomyoviruses as well.
