Fig. 6: Differential gene abundance analysis (DESEQ2) [113] of nifH ASVs from Clusters I to III, between the tissue and skeleton of coral samples.

As Pocillopora had no nifH Clusters I–III ASVs in tissue sequences, it was excluded from this analysis. Results are plotted along a log₂ scale, with an axis break to include an ASV of the order Syntrophobacterales.
