- Abstract
Additional file 1: Table S1. Summary of variation in ecology and skin morphology for the five sampled caecilian species. Dermal fold (annulation) system categories as follows: primary = borders between folds aligned with those between underlying somites and vertebrae; secondary = folds midway between borders underlying somites and vertebrae; “tertiary” = many folds, not aligned with underlying somites and vertebrae (see Gower and Wilkinson [2007], and Wilkinson and Nussbaum [17]. Degree of fossoriality (see Bardua et al. [2019]) and habitat is based on observation in the field (DJG, DSM, MW pers. obs.). See San Mauro et al. [21], Taylor [14], and Wilkinson, Sherratt, Starace, and Gower (2013) for more information on morphology and maternal dermatophagy. Table S2. Tissue sample information and experimental design for the differential expression analysis. Table S3. Characterisation of significantly up-regulated sequences in the caecilian skin transcriptomes. Table S4. Antimicrobial peptide annotation (APD31, DADP2, Uniprot terms: Andersonin3, Cathelicidin4, Cecropin5 and Magainin6) and occurrence (indicated by an X) in skin transcriptomes of the five sampled caecilian species. Table S5. Peptide pheromones annotation and occurrence (indicated by an X) in skin transcriptomes of the five sampled caecilian species. Table S6. Annotated AMPs and p-values for Wilcoxon signed-rank test of differences between AMP expression levels in midbody and posterior skin samples. * indicates selfbuilt databases for subset of entries for these UniProt terms (see Materials and Methods). For R. bivittatum, data were available only for midbody skin. Figure S1. PCA plots of PC1 versus PC2 (first column), PC2 versus PC3 (second column), and PC1 versus PC4 (third column) showing variance among gene expression levels in various tissue types across the five sampled caecilian species. Samples were color coded by tissue type (first row), species (second row), and sequencing company (third row). Figure S2. Network graphs for GO domains (A: biological process, B: molecular function and C: cellular component) of skin up-regulated genes. Greater colour intensity indicates higher fold change in expression in caecilian skin, and circle size is positively correlated with number of genes with the same GO in the UniProt database. Figure S3. Expressed sequences annotated as encoding peptides and their presence in the skin of the five sampled caecilian species.
