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

Our study investigates the role of the swollen fingers of two dendrobatid species, Leucostethus brachistriatus, and Epipedobates anthonyi, 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
