High diversity of crustose coralline algae microbiomes across species and islands, and implications for coral recruits
The study significantly expands the number of characterized CCA microbiomes, and provides new insight into the extensive diversity of these microbial communities. We show distinct microbiomes between and within CCA species, characterized by specific chloroplast 16S rRNA gene sequences. We term these distinct groups "chlorotypes", and demonstrate their utility to differentiate CCA. We also show that only few bacterial taxa were shared between CCA and coral recruits growing in contact with them. Nevertheless, we observed that the microbial community of coral recruits varied depending on the substrate they grew on. We conclude that CCA and their associated bacteria influence the microbiome composition of the coral recruits.
