The Maize Genome Mapping Project

Topics: genetics plant genetics


One of Cone’s earlier research projects on corn genetics is the Maize Mapping Project. Funded by the National Science Foundation as part of the Plant Genome Research Program, the project involved a collaboration of investigators at MU, the University of Arizona, and the University of Georgia. Of the four-year project that was completed in 2002, Cone recounts: “Our goal was to make a map of the maize genome.” Using molecular methods and a genetic population tailored specifically for the project, Cone’s research team set about placing DNA “landmarks” onto the chromosomes. “When we finally finished the map,” she says, “there were over 10,000 landmarks on it!”
