Methods & Sampling

Methodology:

Sampling and analytical procedures:

A 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). One fragment from 6 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 micro centrifuge at 30 oscillations per second for 30 s. 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.

Data Processing Description

Processing notes from researcher:

BBSplit was used to map quality-filtered (fast v0.20.1) reads to coral or Symbiodiniaceae transcriptome and generate three read files: (I) coral, (ii) Symbiodiniaceae, and (iii) noncoral/non-Symbiodiniaceae. Noncoral/non-Symbiodiniaceae reads were uploaded to NCBI.

BCO-DMO processing description:

Converted dates to YYYY-MM-DD or YYYY-MM formats where appropriate
Removed apostrophes (') from Dive_Site column
Replaced spaces (" ") with underscores (_) in column headers
Converted lat and long from degrees, hours, seconds to decimal degrees format (64˚55'33.5"W → -64.925972)

Supplied Description:

Instrument Type

Generic Name: Qiagen TissueLyser II

Generic Description:

The Qiagen TissueLyser II is a tissue processor designed to disrupt biological samples through high-speed shaking in plastic tubes with stainless steel, tungsten carbide, or glass beads. It is used for high-throughput disruption of human, animal, and plant tissues, bacteria, and yeast to access biological information for genomics, transcriptomics, and proteomics applications. It automates the purification of DNA, RNA, and protein from 1 to 96 samples. Disruption and homogenization are achieved through the beating and grinding effect of beads on the sample material as they are shaken together in the grinding vessels. Using the appropriate adapter set, up to 48 or 192 samples can be processed at the same time. Alternatively, a grinding jar set can be used to process large samples. A range of beads, bead dispensers, and collection microtubes and caps are also available. It can be programmed to provide variable speeds from 3 to 30 Hz (180-1800 oscillations per minute) and run times from 10 seconds to 99 minutes.
