Snakes of the Philodryadini tribe are included in the Dipsadidae family, which is a diverse group of rear-fanged snakes widespread in different ecological conditions, including habitats and diet. However, little is known about the composition and effects of their venoms despite their relevance for understanding the evolution of these snakes or even their impact on the occasional cases of human envenoming. In this study, we integrated venom gland transcriptomics, venom proteomics and functional assays to characterize the venoms from eight species of the Philodryadini tribe, which includes the genus , and .

Article Synopsis
  • This study investigates how snake venom changes as snakes grow, focusing on variations in venom composition among different-sized individuals.
  • Researchers decoded venom gland transcripts from six snakes and analyzed venom proteins from 19, identifying 125 toxin transcripts, with only 10 linked to growth changes.
  • The findings indicate that larger snakes primarily produce myotoxic phospholipases A, while smaller snakes have venom that is more hemorrhagic and pro-coagulant due to unique metalloproteinases, showing that transcriptional changes play a key role in venom variability.
