Data from: Sexy fingers: Pheromones in the glands of male dendrobatid frogs

<p>Our study investigates the role of the swollen fingers of two dendrobatid species, <em>Leucostethus brachistriatus, </em>and <em>Epipedobates anthonyi,</em> in pheromone production using whole-transcriptome sequencing (RNAseq). We examined differential gene expression in the swollen versus non-swollen fingers and toes. The overwhelming pattern of gene expression in both species was strong upregulation of sodefrin precursor-like factors (SPFs) in swollen fingers, a well-known pheromone system in salamanders. As part of the results, we include a fasta-file with the RNA-seq assemblies from each species, as well as their annotation and Differential expression (DE) analyses. Likewise, we include the alignment of some of the most highly expressed sodefrin precursor-like-factor (SPF) sequences</p>
