摘要
作物种质资源中蕴含着大量优异等位基因,如何鉴定并将这些变异应用于作物遗传改良是种质资源研究的中心任务之一。等位基因挖掘对种质资源遗传多样性分析、作物起源与演化研究、重要性状形成的分子基础阐释、种质创新与作物育种具有重要意义,也是作物分子设计育种的基石。因此,未来需要进一步研发更加高效的等位基因挖掘策略与技术方法,加速优异等位基因的发现及其在作物遗传改良中的应用。本文重点评述了等位基因发掘的主要策略与技术途径,提出了今后的重点任务与发展方向。
The superior and/or novel alleles(even rare alleles)for a particular trait are often detectable in crop germplasm resources.Exploration and application of allelic variations in crop genetic improvement is one of the tasks in the field of germplasm resources.Allele mining,which is an important tool in deciphering the genetic diversity,the origin and evolution,the molecular mechanism of important agriculture traits as well as germplasm innovation,etc.,is the cornerstone of crop breeding by molecular design.There is a great demand on development of high-throughput,efficient allelic mining approaches,in order to accelerate the discovery of excellent alleles and their application in future crop improvement.For this purpose,here we review the major methods of the allelic discovery and propose the research priorities and focuses.
