“国际水稻基因组测序计划”始于1998年,由日本、美国、中国等10个国家和地区参加,定位了水稻中的37500个基因,并率先在动植物中完成了对着丝粒的测序。2002年底,科学家们初步绘制完成了水稻基因组草图。其中中国科学家圆满完成了水稻4号染色体的精细序列测定和分析工作。英国《自然》杂志日前刊登了这张迄今为止最精确、最完整的水稻全基因组序列图,这也是目前在 “The International Rice Genome Sequencing Program” started in 1998 with the participation of 10 countries and regions such as Japan, the United States and China. It locates 37,500 genes in rice and spearheads the completion of the centromere in animals and plants Sequencing. By the end of 2002, scientists initially mapped and completed the rice genome sketch. Among them, Chinese scientists successfully completed the fine sequence determination and analysis of chromosome 4 in rice. British magazine Nature recently published the most accurate and complete rice genome sequence map to date,
