The map-based complete rice genome sequence is now freely available to researchers worldwide, providing the most fundamental tool that should further accelerate efforts to improve the staple crop that feeds more than half the world's population. The finished-quality sequence covers 95% of the 389-Mb genome, including virtually all of the euchromatin and two complete centromeres. A total of 37,544 non-transposable-element-related protein-coding genes were identified. The complete genetic information on rice will serve as a gold mine for genomic research in rice and other cereal species. It will facilitate the identification of many important genes by both forward and reverse genetics strategies, and clarify the relationships between sequence variation and phenotypes. The genome sequence derived from Oryza sativa subspecies japonica can be used as a reference sequence for comparative analysis among Oryza species that will help in understanding the major factors involved in speciation and searching for useful genetic resources. Furthermore, the completed sequence will also serve as a standard for cereal genome comparison and identification of rice orthologous genes in other cereal crops, thereby providing a platform for establishing the genomics of each cereal species.
