Newswise - Scientists at New York University and the University of Chicago have created fruit flies carrying reconstructed ancient genes to reveal how ancient mutations drove major evolutionary changes in embryonic development-the impact of which we see today. (newswise.com)
By introducing individual mutations that happened in the deep past into the ancient genes, we were able to show precisely how each one affected development many millions of years ago," explains Stephen Small, an NYU biologist and one of the paper's senior authors. (newswise.com)
The laboratories of NYU's Small and the University of Chicago's Thornton approached this problem in an innovative way: computationally inferring ancient gene sequences based on their modern descendants, chemically recreating the genes, and then putting them into fly embryos, thereby creating transgenic embryos-i.e., those inserted with a foreign gene-to follow their effects on development in the laboratory. (newswise.com)
Bicoid serves as the "master regulator" of anterior development by turning on expression of a set genes that carry out head development and suppress tail development, and doing so only at the anterior end. (newswise.com)
But the bicoid gene does not even exist in other insects or more distantly related animals, which use other genes to control anterior development. (newswise.com)
Their initial results showed that flies carrying the precursor gene fail to develop a head, with tails at both ends and none of the key genes involved in head development properly expressed. (newswise.com)
When introduced into fly embryos, this evolutionary mutant version of bicoid activated most of the genes involved in head development in their proper places, and the embryos formed recognizable, albeit incomplete, head structures instead of tail structures at the anterior end. (newswise.com)
