Abstract

Raw RNA sequence data were obtained from a disease transmission experiment carried out at the University of the Virgin Islands in which five reef-building coral species, Colpophyllia natans, Orbicella annularis, Pseudodiploria strigosa, Porites astreoides, and Montastraea cavernosa, were exposed to Stony Coral Tissue Loss Disease (SCTLD) in mesocosms. Sequences were used to compare the differential expression of host and endosymbiont genes between disease states (control, disease-exposed, and di...

A Stony Coral Tissue Loss Disease (SCTLD) transmission experiment was carried out at the University of the Virgin Islands (UVI) in April of 2019 and is described in Meiling et al. (2021).

Coral colonies were collected from Rupert's Rock Reef (18.3277 N, -64.926 E) from March 17 to April 02 of 2019. One fragment from five species of stony coral was placed into a control mesocosm equidistant from a central healthy coral colony. Corresponding genet fragments were placed into an experimental mesocosm equidistant from a SCTLD-infected coral colony. This paired design was replicated for a total of 8 genets per species. Experimental coral fragments that developed lesions were removed and stored at -80ºC for RNA sequencing when 30% tissue loss was achieved. Corresponding control coral fragments were removed and stored at the same time. Tissue samples were harvested from the fragments and total RNA was extracted using the RNAqeous-4PCR total RNA isolation kit (Invitrogen, Life Technologies AM1914) as explained in Veglia et al. (2022). Tissues were lysed using a refrigerated Qiagen TissueLyser II microcentrifuge at 30 oscillations per second for 30 seconds. Contaminating DNA and chromatin were removed from the total RNA using the Ambion DNase I (RNase-free) kit (Invitrogen, Life Technologies AM2222). Samples were preprocessed by Novogene Co., Ltd. for mRNA enrichment using polyA tail capture; the mRNA libraries underwent 150-bp, paired-end sequencing on an Illumina NovaSeq 6000 instrument using the NEBNext Ultra II RNA library prep kit.
