摘要
大麦(Hordeum vulgare L.)是世界上重要的谷类作物之一,其二倍体特性使其成为麦类作物基因组研究的重要材料。随着大量分子标记图谱、BACs文库、突变集合和DNA阵列技术的应用,大麦基因组测序工作已不断深入,越来越多的大麦基因组信息使综合分析大麦基因组结构和功能,了解基因表达网络同重要农艺性状之间的关系成为可能。就大麦基因组研究内容,如ESTs系统、物理图谱的构建、功能基因组学研究和大麦分子育种研究作简要综述,为进一步阐述大麦基因组结构和功能特性,提高大麦分子育种能力提供理论依据。
Barley is one of the major cereal crops in the world.Due to its diploid nature,barley can be considered an important material for Triticeae genomic studies.With the application of techniques and methods employed in genomics,such as a large number of mapped molecular markers,BAC libraries,mutant collections and DNA arrays,the sequencing of barley genome has deepen increasingly.More and more information about the barley genome pave the way for a comprehensive analysis of structural and functional genomics of barley as well as understanding of gene expression networks linked to agronomically important traits.Progress in genomics and molecular breeding of barley were summarized,including ESTs system,physical map construction,functional genomics and barley marker-assisted selection,which provides a theoretical basis for further improving molecular breeding and expounding the structural and functional performance of barley genome.
