China's top 10 events of ST progress in 2002 was revealed at a press conference jointly organized by the Chinese Academy of Sciences (CAS) and the Chinese Academy of Engineering (CAE) on January 26 in Beijing. These ST achievements were selected by 568 CAS and CAE members. Refined Map of Rice Genome and Detailed Sequencing Map of Rice Chromosome 4 Completed by the CAS Genomics and Bioinformatics Center, the refined map of indica rice covers 97 percent of its genetic sequences, among which 97 percent are precisely positioned on the chromosomes, and the precision rate of 94 percent of the single bases in the sequence is up to 99.99 percent, reaching the international standards for a refined genetic map. As part of an international effort to precisely sequence the rice genome, researchers from labs like National Center for Gene Research completed the sequence of the rice Chromosome 4 to an accuracy of greater than 99 percent, making a crucial contribution to the human's eventually demystification of the rice's genetic code.
