Rice production in the United States by 382 pounds per acre. Six states now account for over 99% of all rice grown in the US. These are Arkansas, California, Louisiana, Mississippi, Missouri and Texas. As of 2003, Arkansas topped the list with a production level of 213 million bushels against a total production of 443 million bushels in the country, and the annual per capita consumption reported is in excess of 28 pounds. The earliest types grown in Carolina were the African "Oryza glaberrima", the prized "Carolina Gold". Asian "Oryza sativa" was "Carolina White". After the total decline of rice cultivation in Carolina, "Carolina Gold" is
Plant genome assembly products were used to clone remaining gaps, and YACs allowed the characterization of telomere sequences. The resulting sequenced regions were 115.4 Mb of the 125 Mb predicted size of the genome and a total of 25,498 of protein-coding genes. To sequence and assemble the genome of Oryza Sativa (japonica), the same strategy was used. For Oryza Sativa a total of 3,401 mapped clones in a minimum tiling path were selected from the physical map and assembled. One of the most important crops in the world, maize (Zea mays), is the last plant genome project primarily based on Sanger BAC-by-BAC strategy.
