Data from: Whole genome duplication and transposable element proliferation drive genome expansion in Corydoradinae catfishes
Genome size varies significantly across eukaryotic taxa and the largest changes are typically driven by macro-mutations such as whole genome duplications (WGDs) and proliferation of repetitive elements. These two processes may affect the evolutionary potential of lineages by increasing genetic variation and changing gene expression. Here we elucidate the evolutionary history and mechanisms underpinning genome size variation in a species rich group of Neotropical catfishes (Corydoradinae) with extreme variation in genome size - 0.6pg to 4.4 pg per haploid cell. Firstly, genome size was quantified in 65 species and mapped onto a novel fossil-calibrated phylogeny. Two evolutionary shifts in genome size were identified across the tree - the first between 43-49 Mya (95% highest posterior density (HPD) 36.2-68.1 Mya) and the second at ~19 Mya (95% HPD 15.3-30.14 Mya). Secondly, RAD sequencing was used to identify potential WGD events and quantify transposable element abundance in different lineages. Evidence of two lineage scale WGDs were identified across the phylogeny, the first event occurring between 54-66 Mya (95% HPD 42.56-99.5 Mya) and the second at 20-30 Mya (95% HPD 15.3-45 Mya) based on haplotype numbers per contig and between 35-44 Mya (95% HPD 30.29-64.51 Mya) and 20-30 Mya (95% HPD 15.3-45 Mya) based on SNP read ratios. Transposable element abundance increased considerably in parallel with genome size, with a single TE-family (TC1-IS630-Pogo) showing several increases across the Corydoradinae, with the most recent at 20-30 Mya (95% HPD 15.3-45 Mya) and an older event at 35-44 Mya (95% HPD 30.29-64.51 Mya). We identified signals congruent with two WGD duplication events, as well as an increase in TE abundance across different lineages, making the Corydoradinae an excellent model system to study the effects of WGD and TEs on genome and organismal evolution.
