Oryza glaberrima a marais)”. The Portuguese accounts speak of the Falupo Jola, Landuma, Biafada, and Bainik growing rice. André Álvares de Almada wrote about the dike systems used for rice cultivation, from which modern West African rice dike systems are descended. African rice was brought to the Americas with the transatlantic slave trade, arriving in Brazil probably by the 1550s and in the U.S. in 1784. The seed was carried as provisions on slave ships, and the technology and skills needed to grow it were brought by enslaved rice farmers. Newly imported African slaves were marketed (and sometimes even trained) for their
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.
