Figure 3. Relative abundance of amplicon sequence variants of the V4 region of 16S rRNA genes in nursery-reared Acropora cervicornis, colored by bacterial order.

Samples are grouped by coral genotype: (A) green (G), (B) red (R), and (C) yellow (Y) and by location within the colony: basal branches (1°), intermediate branches (2°), and apical colony tips (3°).
