Alan Jones, PhD, Kenan Distinguished Professor of Biology and Joint Professor of Pharmacology, published a paper in Science Signaling this week with an accompanying cover featuring the article. The Online Cover “features a that describes the evolution and function of two distinct families of G伪 proteins in plants. The XLG family is similar to the hare, rapidly evolving to enable adaptation to living on land; whereas the canonical G伪 family is similar to the tortoise, slowly evolving and maintaining interactions with binding partners.
