Rice - the prequel

Researchers hoping to decipher the first complete genome sequence of a plant fear the lengthy clusters of repeated transposon sequences present in many plant genomes. But in the July issue of Genome Research, Mao et al. report promising news for the international consortium tackling the rice genome (Genome Res. 2000, 10:982-990). After sequencing 73,000 DNA fragments distributed through the rice genome (a total of nearly 50 Mb), Mao et al. find that less than 10% of the sequences contain transpo

Researchers hoping to decipher the first complete genome sequence of a plant fear the lengthy clusters of repeated transposon sequences present in many plant genomes. But in the July issue of Genome Research, Mao et al. report promising news for the international consortium tackling the rice genome (Genome Res. 2000, 10:982-990). After sequencing 73,000 DNA fragments distributed through the rice genome (a total of nearly 50 Mb), Mao et al. find that less than 10% of the sequences contain transposons. Thus transposons should not interfere substantially with the completion of the rice genome sequence. Mao et al. also confirm that transposons called miniature inverted-repeat transposable elements (MITEs) are associated with genes, and thus provide a good way to spot genes in the rice and possibly other plant genomes.
