摘要: 采用28个RFLP籼粳特异性探针和6个SSR籼粳特异性标记对水稻不同品种进行了籼粳基因组多态性分析,结果表明,这些标记分布在水稻12条染色体上,能对水稻品种进行籼粳稻分子分类。由于水稻基因组序列图的完成和释放,使得这些籼粳特异性标记揭示的基因组多态性可以在基因组序列水平上进行分析和验证。本研究以RZ906探针和RM405为例分析了籼粳特异性其及序列分子生物学基础。

Abstract: Variation of Indica and Japonica rice were analyzed by using 28 RFLP probers and 6 SSR markers. The result indicated that Indica and Japonica rice can be classified by these markers. The publication of the genome sequences of rice facilitated the development of markers of sub-species and analysis of genome polymorphisms. RZ906 and RM405 markers were analyzed as examples.
