分子标记技术在作物育种中的应用与展望

回顾分子标记的发展,介绍了一些有代表性的分子标记在生态学,聚类分析,品种差异性分析以及分子育种中等多方面的应用,并总结了它们的优缺点.随着深度测序技术的发展和多种序列信息库的完善,预测了未来分子标记的发展方向——功能性分子标记(Functional molecular marker),这种新型的分子标记技术利用了基因中的一些功能元件或者重要的单碱基多态性(SNP)位点,提高了在应用中的分辨率和灵敏度.

Application and Perspective of Molecular Marker Technology in Crop Breeding

This paper reviews the development of molecular markers and introduces some typical molecular markers applying for ecology,cluster analysis,species diversity analysis,molecular breeding of crops and so on,as well as,summarizes their advantages and disadvantages.With the development of deep sequencing technology and the improvement of sequence information database,functional molecular markers will be the future development direction of molecular marker research.The new type of molecular marker takes advantage of some functional components or important single-base polymorphism(SNP)sites in gene to improve the sensitivity and resolution in the application.
