Abstract Rice is the principal food for over half of the population of the world. With
its genome size of 430 megabase pairs (Mb), the cultivated rice species Oryza
sativa is a model plant for genome research. Here we report the sequence
analysis of chromosome 4 of O. sativa, one of the first two rice chromosomes to
be sequenced completely. The finished sequence spans 34.6 Mb and represents
97.3% of the chromosome. In addition, we report the longest known sequence for a
plant centromere, a completely sequenced contig of 1.16 Mb corresponding to the
centromeric region of chromosome 4. We predict 4,658 protein coding genes and 70
transfer RNA genes. A total of 1,681 predicted genes match available unique rice
expressed sequence tags. Transposable elements have a pronounced bias towards
the euchromatic regions, indicating a close correlation of their distributions
to genes along the chromosome. Comparative genome analysis between cultivated
rice subspecies shows that there is an overall syntenic relationship between the
chromosomes and divergence at the level of single-nucleotide polymorphisms and
insertions and deletions. By contrast, there is little conservation in gene
order between rice and Arabidopsis.
