Rice cooker grain shape, and grain composition. There are three main types of Asian rice: "Oryza sativa" subsp. indica, i.e., Indian rice (long grain rice, e.g., basmati rice and Thai jasmine rice), "O. sativa subsp. javanica", i.e., Java rice (large grain rice) and "O. sativa subsp. japonica", i.e., Japanese rice (medium grain rice, e.g., Calrose rice, short grain rice, e.g., most Japanese rice and risotto rice). African rice, "Oryza glaberrima", is an entirely separate species, but can be cooked in the same way. Zizania is not even in the same genus, although it is often called a rice (or "water oats"); it
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.
