Figure 2. Relative abundance of V. fischeri and other conserved taxa associated with juvenile and adult squid.

(A) Relative abundance of V. fischeri, other vibrios, and non-vibrio taxa in juvenile squid, juvenile squid ventate, and adult squid. The percentage of reads identified as V. fischeri in each sample is indicated on the y-axis (% Vf). In wild-caught adult panel, MB* indicates animal identifier, with A or B indicating paired samples from each lobe of the same light organ. (B) Corresponding relative abundance of non-V. fischeri taxa in the samples described in panel A. Taxa are plotted at the family level, and Vibrionaceae excludes ASVs identified as V. fischeri. Unidentified Bacteria correspond to ASVs that were not assigned taxonomy past the kingdom level, likely due to a lack of similar sequences in available hsp60 reference sequences. Other Taxa correspond to ASVs that were assigned taxonomy to at least the family level but make up < 0.1 % of the total read abundance. Sample order is consistent between panel A and panel B.
