水稻第四号染色体精确测序完成

Rice Genome Sequencing Project:Rice chromosome 4 cross the finishing line

水稻是最重要的粮食作物之一,是世界约一半以上人口的主要口粮。水稻作为禾本科植物基因组研究的模式作物,具有十分重要的意义。中国科学院国家基因研究中心率先完成了国际水稻基因组计划的第4号染色体全长序列的精确测序,该成果已在英国的《自然》杂志发表。本文简要报告水稻基因组测序的意义和目前我国在这一领域已取得的进展,并着重介绍水稻基因组4号染色体精确测序和分析的成果。

Rice is the principal food for over half of the population of the world.With its genome size of 430 megabase paris (Mb),the cultivated rice species Oryza sativa is a model plant for genome research.As part of international efforts to completely sequence the entire rice genome,National Center for Gene Research has finished the sequence and analysis of rice chromosome 4.Here we introduce the paper on the rice chromosome 4 sequence and analysis which has been recently published in Nature.
