2.1 Data sources
We determined studies as relevant by the description of the sampling environment in their SRA metadata and manuscripts. Our selected studies measured Acropora coral gene expression change in response to environmental stress with RNA-seq or Tag-seq. From the four studies we selected, we had a total of five environmental stress contrasts, each between a population in a non-stressed and stressed environment (Table 1 and Figure 2). We treated the Symbiodiniaceae genus contrast as stress-related as well, Cladocopium implying higher coral stress level than Durusdinium , since that was the finding of the original study based on gene expression analysis of the coral host (Barfield et al., 2018).
