Extended Data Fig. 2. The 16 S rRNA gene is conserved across the genomes sampled.
The 16 S rRNA gene was extracted from all genomes and aligned. The topmost sequence is the ASV found to be most abundant in our reanalysis of two rumen epithelial amplicon studies22,23. Only the first 600 of 1508 positions are shown, as there was no variation observed across the rest of the alignment. On the left had side, sequences that were extracted from the same genome are shown (indicated with brackets). Two variants were detected in 4 genomes and are indicated by the genome names in red. The most divergent of the two variants (9 bp changes) is represented as one of the copies of the rRNA gene within the closed reference genome VBCF_01 NA2. A single base pair change defines the remaining variant detected in genomes JMF_06 NA1 and JMF_09 ED2.
