Extended Data Fig. 6: Ribosomal protein analyses and phylogenies.
From: Borgs are giant genetic elements with potential to expand metabolic capacity
(A) The array of single-copy archaeal ribosomal genes (columns) vs. Borg (blue) and Methanoperedens spp. (gold) genomes illustrating that although Borgs often have rpL11 and occasionally, other ribosomal proteins, they do not have the gene inventory needed to construct ribosomes. (B) Left; Dendrogram of hierarchical clustering of all-vs-all Pearson correlation values between all Borgs and Methanoperedens spp. from the wetland. Right; Maximum Likelihood Phylogeny of concatenated ribosomal proteins from Methanoperedens species that do and do not coexist with Borgs and previously reported genomes. We found no data indicating the presence of Borgs in samples containing previously reported Methanoperedens genomes. We searched for Borgs in the samples highlighted in blue using the same methods used to detect Borgs in this study and concluded that they do not contain Borgs. A subset of the Borg-free samples contain Methanoperedens spp. at very high abundance levels.
