In this work, samples for DNA collection from waters around an Acropora pulchra colony were taken in April 25th, 2018 (12:00 local time) at the Tema’e beach reef of Mo’orea (French Polynesia). Water samples were withdrawn from three different local sites around the colony, at a depth of ~1 m: (IN) between the living branches, ~1 cm next to the polyps (AL) deeper between the branches, ~1 cm next to the coral skeleton colonized by turf algae and (OUT) 2 meters down current from the patch over a sandy bottom ~2 m deep. At that sampling point, 0.8 L (IN and AL) and 2.5 L (OUT) seawater were sampled and were prefiltered through 200-µm mesh. The microbial biomass was then collected on 0.2 µm pore-size, 47 mm diameter polycarbonate filters using a peristaltic pump. The filters were flash frozen in liquid N2 and stored at -80°C. Total DNA was extracted using the phenol-chloroform protocol as described in Massana et al. (1997). Prokaryotic diversity was determined by amplicon sequencing of the V4/V5 regions of the 16S rDNA genes using the Illumina MiSeq platform and paired-end reads (2 x 250 bp). PCR amplifications were done using the prokaryotic universal primers 515F-Y (5'- GTGYCAGCMGCCGCGGTAA-3’) and 926R (5’-CCGYCAATTYMTTTRAGTTT-3’) (Parada et al. 2016). All samples were sequenced at the Research and Testing Laboratories (RTL, Lubbock, TX, USA). References: Massana, R., Murray, A. E., Preston, C. M., and DeLong, E. 1302 F. (1997).
