- Effects of Gene Duplication, Positive Selection, and Shifts in Gene Expression on the Evolution of the Venom Gland Transcriptome in Widow Spiders.
- Haney RA1, Clarke TH2, Gadgil R3, Fitzpatrick R3, Hayashi CY4, Ayoub NA5, Garb JE1.
- Genome biology and evolution.Genome Biol Evol.2016 Jan 5;8(1):228-42. doi: 10.1093/gbe/evv253.
- Gene duplication and positive selection can be important determinants of the evolution of venom, a protein-rich secretion used in prey capture and defense. In a typical model of venom evolution, gene duplicates switch to venom gland expression and change function under the action of positive selecti

- The eggs of black widow spider (L. tredecimguttatus) have been demonstrated to be rich in toxic proteinaceous components. The study on such active components is of theoretical and practical importance. In the present work, using a combination of multiple biochemical and biological strategies, we iso

- BACKGROUND: The brown widow spider (Latrodectus geometricus Koch, 1841) has colonised many parts of the world from its continent of origin, Africa. By at least 1841, the species had successfully established populations in South America and has more recently expanded its range to the southern states
