    芍药属植物分子水平遗传多样性研究进展

    Research advances in molecular genetic diversity of Paeonia L.

    • 摘要: 芍药属植物种质资源丰富,种及品种繁多,具有重要的观赏价值和药用价值。从分子水平上系统论述了芍药属中种质资源较为丰富的牡丹组与芍药组的遗传多样性研究进展,认为:种源不同是造成芍药属遗传差异的最主要因素;在种源一致的前提下,其遗传多样性与部分形态特征尤其是花色、花型、株高存在很大的相关性。所有分子标记技术与DNA序列分析所得的研究结果差异很大,但可以肯定的是:基于形态学分类将牡丹组划分为2个亚组是完全合理的;研究者大多“重牡丹而轻芍药”,使得在分子水平上对芍药组植物遗传多样性的研究还是不够深入。今后须综合利用多种遗传标记及序列分析手段,加快芍药属全基因组序列的开发与各种新型标记方法的探索应用。同时,对芍药属植物遗传多样性研究趋势进行了展望,以期为该属植物的资源保护与利用提供科学借鉴。

       

      Abstract: Germplasm resources are rich and the species and the varieties are wide in Paeonia L., which is of important ornamental and medicinal value. This paper systematically discusses the research advances in genetic diversity of Paeonia Sect. Moutan DC and Sect. Paeonia, which contain relatively rich germplasm resources from the level of DNA molecular. It was suggested that different provenances were the main factor contributing to the genetic differences in Paeonia; genetic diversity had a great correlation with flower color, flower type and plant height only on the premise of consistent provenance. All the research results were widely different by molecular markers and DNA sequence analysis, but it could be sure that dividing Sect. Moutan into two subsections was perfectly reasonable; most researchers paid more attention to P. suffruticosa than to P. lactiflora, as a result, research activities on genetic diversity in Sect. Paeonia were still not deep\|going enough. Henceforth, we must utilize comprehensively various genetic markers and sequence analysis to accelerate the development of whole genome sequences in Paeonia, and further the exploration and application of all kinds of new marker methods. Meantime, the advance research direction of genetic diversity in Paeonia was presented, which will undoubtedly provide scientific references and information on the conservation and utilization of Paeonia resources.
