Abstract

We have produced a draft sequence of the rice genome for the most widely cultivated subspecies in China, Oryza sativa L. ssp. indica, by whole-genome shotgun sequencing. The genome was 466 megabases in size, with an estimated 46,022 to 55,615 genes. Functional coverage in the assembled sequences was 92.0%. About 42.2% of the genome was in exact 20-nucleotide oligomer repeats, and most of the transposons were in the intergenic regions between genes. Although 80.6% of predicted Arabidopsis thaliana genes had a homolog in rice, only 49.4% of predicted rice genes had a homolog in A. thaliana. The large proportion of rice genes with no recognizable homologs is due to a gradient in the GC content of rice coding sequences.

摘要

我们通过全基因组鸟枪法测序，获得了中国种植最广泛的亚种——水稻（Oryza sativa L. ssp. indica）基因组的草图序列。该基因组大小为466兆碱基，估计有46,022至55,615个基因。组装序列的功能覆盖率为92.0%。约42.2%的基因组由精确的20核苷酸寡聚体重复序列组成，并且大多数转座子位于基因间区域。虽然预测的拟南芥基因中有80.6%在水稻中有同源物，但预测的水稻基因中只有49.4%在拟南芥中有同源物。水稻中大量没有可识别同源物的基因是由于水稻编码序列的GC含量存在梯度。
