The rice genome is estimated at 430 Mb (Arumuganathan and Earle, 1991) and the nonredundant sequence available to date from the IRGSP is 358 Mb (http://www.tigr.org/tdb/e2k1/osa1/pseudomolecules/info.shtml).
Number of genes in Arabidopsis from Release 5 of the TIGR ATH1 database (http://www.tigr.org/tdb/e2k1/ath1/ath1.shtml) is 26,207 protein coding genes and 3,786 pseudogenes, which includes the transposable-element related gene models.
Number of gene models in rice from Release 1 of the TIGR OSA1 database (http://www.tigr.org/tdb/e2k1/osa1/pseudomolecules/info.shtml) includes approximately 45,000 protein coding gene models and approximately 11,000 transposable element related gene models.
Number of ESTs from Release 011604 of the GenBank dbEST database (http://www.ncbi.nlm.nih.gov/dbEST/dbEST_summary.html). NA, not available.
