Along with red, green is the color of this holiday season. And bright green is showing up in more than just decorations. In Guangdong Province in Southern China, ten transgenic piglets have been born this year, six of them since August, and under a black light, they glow a greenish tint.
A technique developed by reproductive scientists from the University of Hawai`i at Mānoa's John A. Burns School of Medicine was used to quadruple the success rate at which plasmids carrying a fluorescent protein from jellyfish DNA were transferred into the embryo of the pig. Drs. Zhenfang Wu and Zicong Li of the South China Agricultural University have detailed the research that produced the transgenic pigs in an academic manuscript recently submitted to the Biology of Reproduction journal. Dr. Zicong is a UH alumnus. Also assisting in the manuscript was Dr. Johann Urschitz, an Assistant Research Professor in the UH medical school's Institute for Biogenesis Research (IBR).
