Fig 2. Characterisation of symbiont communities in the southern PAG and Gulf of Oman.

(A) Bar charts indicate the proportion of colonies hosting each ITS2 type or combination of ITS2 types. Vertical separation within the bars indicates colonies where more than one symbiont type was present. (B) Radial phylogenetic tree depicting the relationships between C3 variants found in P. daedalea from PAG reefs, C3 variants from Porites spp. within the region and other C3 variants found elsewhere. The tree was generated by Bayesian inference analysis of the psbA^ncr region using the alignment generated in a previous study [18]. The branches containing samples from this study are shown in red with labelled arrows indicating the location of the samples (D: Delma; S: Saadiyat; R: Ras al Khaimah). The accession numbers for samples used to generate the tree are shown in S3 and S4 Tables.
