摘要:

为了解国内外集群分离分析法(bulked segregant analysis,BSA)在作物育种领域的研究现状与前沿动态,客观反映各国家、机构及研究人员在该领域的影响力,本文基于文献计量学分析方法使用文献计量分析软件CiteSpace对WOS (Web of Science)数据库2000~2023年2111项和CNKI (China National Knowledge Infrastructure)数据库2003~2023年446项研究成果进行关键词共现分析、突显词分析、关键词聚类分析、聚类时间线分析及作者共被引分析。结果表明:BSA在作物育种领域应用的研究成果在国内外的发文趋势相同,国内外期刊发文量均逐年上升;在发文量国家排序中,中国排名第一、美国第二、印度第三。在CNKI数据库中华中农业大学的发文量最多,而在WOS数据库中中国农业科学院的发文量最多。国外BSA在作物育种领域应用的文章主要集中在植物科学、农学、园艺学和遗传学等学科,而国内主要集中在作物学、植物保护学、园艺学、生物学等学科;Michlmore RW、Kosambi DD和Li H这3位作者在该领域的影响力最高,而Michlmore RW、Lander ES、Li H这3位作者与其他作者有更密切的联系。国内研究的热点作物和性状分别是水稻(Oryza sativa)、大豆(Glycine max)、玉米(Zea mays L.)和抗病性、株高;国外研究的热点作物和性状分别是水稻、拟南芥(Arabidopsis thaliana)、小麦(Triticum aestivum L.)和抗病性。目前,BSA在国内集中应用于作物目标性状候选基因及作物突变体突变基因的定位和功能验证,而国外则集中应用于作物目标性状基因的精细定位和功能验证及遗传机制的解析。此外,BSA在作物育种领域应用的研究前沿分析表明,未来在该领域热点研究的对象为水稻、花生(Arachis hypogaea L.)、陆地棉(Gossypium hirsutum L.)、作物突变体和作物代谢产物。

Abstract:

In order to understand the progress and frontier in the application of BSA(bulked segregant analysis) method in crop breeding and to reflect objectively the contribution of different countries, institutions and researchers in this field at home and abroad, this study analyzed 2111 items in the WOS (Web of Science) database from 2000 to 2023 and 446 items in the CNKI (China National through Knowledge Infrastructure) database from 2003 to 2023, regarding the researches of the application of BSA in crop breeding, basing on bibliometric analysis methods using CiteSpace software including keyword co-occurrence analysis, highlight word analysis, keyword clustering analysis, clustering timeline analysis and author co-citation. The results showed that there was an consistent increasing trend in the publication number of the application of BSA in crop breeding both in the domestic and foreign journals year by year. Ranking of the top countries according to the number of publications was China, the United States and India. The Huazhong Agricultural University displayed the highest number of publications in the CNKI database, while the Chinese Academy of Agricultural Sciences was found to have the highest number of publications in the WOS database. The published articles related to the application of BSA in crop breeding abroad mainly focused on the disciplines such as plant science, agronomy, horticulture and genetics, while those in China mainly concentrated on such disciplines as plant science, plant protection, horticulture and biology. The top three authors in terms of influence in the field of appling BSA in crop breeding were Michelmore RW, Kosambi DD and Li H, while Michelmore RW, Lander ES and Li H had closer cooperations with other authors. The top three crops relating to the studies of BSA were rice(Oryza sativa), soybean(Glycine max), corn(Zea mays L.) with the hot spot traits of disease resistance and plant height domestically. The top three crops involving the studies of BSA were rice, Arabidopsis thaliana and wheat(Triticum aestivum L.) with hot spot traits of disease resistance abroad. Up to now, BSA was mainly used to localize and functionally verify the candidate genes linking target traits and the mutated genes in crops in the domestical documents, while the foreign published studies based on BSA were mainly focused on the fine mapping and functional verification of target trait genes aiming at the revelation of genetic mechanisms in crops. Research frontier analysis indicated that rice, peanuts(Arachis hypogaea L.), upland cotton(Gossypium hirsutum L.) would be the main objects of studies concerning application of BSA in crop breeding with the hot topics of crop mutants and crop metabolites in the future.
