 *To distinguish allelic differences between the genome sequence and the NIAS and CSHL re-sequenced individuals,the researchers examined three datasets, NIAS, CSHL, and NIAS + CSHL, that had average read depths of 7.9, 35.7, and 43.6, respectively. With respect to coverage, at least one read uniquely aligned to the pseudomolecules thereby covering 79.4% (NIAS), 90.5% (CSHL), or 90.6% (NIAS + CSHL) of the reference genome (Figure 1)

 *The Nipponbare genome assembly was updated by revising and validating the minimal tiling path of clones with the optical map for rice. Sequencing errors in the revised genome assembly were identified by re-sequencing the genome of two different Nipponbare individuals using the Illumina Genome Analyzer II/IIx platform. A total of 4,886 sequencing errors were identified in 321 Mb of the assembled genome indicating an error rate in the original IRGSP assembly of only 0.15 per 10,000 nucleotides.
 *A small number (five) of insertions/ deletions were identified using longer reads generated using the Roche 454 pyrosequencing platform. As the re-sequencing data were generated from two different individuals, the researchers were able to identify a number of allelic differences between the original individual used in the IRGSP effort and the two individuals used in the re-sequencing effort.
 *The revised assembly, termed Os-Nipponbare-Reference-IRGSP-1.0, is now being used in updated releases of the Rice Annotation Project and the Michigan State University Rice Genome Annotation Project, thereby providing a unified set of pseudomolecules for the rice community.

+*Improvement of the Oryza sativa Nipponbare reference genome using next generation sequence and optical map data
 ==The Background of This Project==
 *Rice research has been enabled by access to the high quality reference genome sequence generated in 2005 by the International Rice Genome Sequencing Project (IRGSP). To further facilitate genomic-enabled research, we have updated and validated the genome assembly and sequence for the Nipponbare cultivar of Oryza sativa (japonica group).
