The Genomic Structure of Rice

The genome of Oryza sativa consists of 12 chromosomes, one circular mitochondrial DNA, and a circular chloroplast DNA. Additional information about the rice genome may be found at the TIGR Rice Genome Annotation site. Chromosomes are often drawn as in Figure 1 below: with a short and long arm and an intervening centromeric region. Figure 2 depicts the shapes and relative sizes of the Oryza sativa chromosomes. Table 1 shows the size (in Mbp) and predicted number of genes for each chromosome from Oryza sativa ssp. japonica(Nipponbare).
