NSF-FIBR on gene duplication (proposed)
Papaya, Carica papaya L., has the first plant sex-determining region to be largely sequenced. This achievement together with the recent completion of the whole-genome sequence (WGS), will contribute to better understanding of papaya genome structure and organization. Papaya-DB stores, organizes and makes easily available papaya physical and genetic maps, shotgun WGS and EST sequences, and sex-determining region data to users, as well as providing an external link to the Plant Genome Duplication Database (PGDD) for whole-genome alignments with other plant species. We believe these resources will benefit the scientific community by contributing to answering important questions regarding plant-genome and sex-chromosome origin and evolution.
