Maize is an important crop in many countries of the world. It is used widely for human consumption, animal feed, and industrial materials. It is also considered an exemplar plant species for studying domestication, molecular evolution, and genome architecture. The authors of the research presented in this special collection used the first description of the B73 maize genome to probe some of the most intriguing questions in genetics and plant biology. The ten papers consider maize centromeres, new insights into transposon types and distribution, the abundance of very short FLcDNAs encoding predicted peptides, and many other “genetic jewels”.
Each peer-reviewed article, as well as Virginia Walbot’s editorial introducing the collection, is available online now at the PLoS Genetics website.
