We report improved whole-genome shotgun sequences for the genomes of indica and japonica rice, both with multimegabase contiguity, or almost 1,000-fold improvement over the drafts of 2002. Tested against a nonredundant collection of 19,079 full-length cDNAs, 97.7% of the genes are aligned, without fragmentation, to the mapped super-scaffolds of one or the(More)
BACKGROUND The identification of chromosomal homology will shed light on such mysteries of genome evolution as DNA duplication, rearrangement and loss. Several approaches have been developed to detect chromosomal homology based on gene synteny or colinearity. However, the previously reported implementations lack statistical inferences which are essential to(More)
Understanding the correlation between synonymous substitution rate and GC content is essential to decipher the gene evolution. However, it has been controversial on their relationship. We analyzed the GC content and synonymous substitution rate in 1092 paralogues produced by two large-scale duplication events in the rice genome. According to the GC content(More)
