Theme Evolution of Agricultural Genomics in Recent Years

doi:10.13304/j.nykjdb.2022.0562

Abstract

Abstract:

Agricultural genomics has developed rapidly with a significant increase in information and data. This article summarized the development process of global agricultural genomics in recent years from the perspective of research topic intensity， change paths and research progress. The search strategy used agricultural genome keywords， which were searched from January 2001 to December 2021. Finally， the SCI and SSCI paper datasets were constructed in the Web of Science database， and the topic intensity index system was used to measure the attention and research heat of each cluster. In recent years， the global agricultural genome had achieved remarkable results， transitioning from fundamental exploration to targeted breakthroughs in agricultural applications， and the similarity of research directions increased gradually. In the future， global research hotspots in agricultural genomics would shift towards more multidimensional and high-precision research such as correlation， diversity， and accuracy. Breakthroughs in complete genome， complex genome， and pan genome research and technology， as well as the development of gene chips， those still faced challenges. The results of this article had significant implications for achieving data-based scientific decision-making and technological innovation.

Key words: agriculture, genomics, theme evolution

摘要：

农业基因组学发展迅猛，信息和数据量大增，从研究主题强度、变化路径和研究进展方面总结了全球农业基因组学近年的发展历程。利用农业基因组关键词构建检索式，检索时间从2001年1月至2021年12月，最终在Web of Science数据库中构建SCI和SSCI论文数据集，并以主题强度指标体系来测度各个聚类的受关注度及研究热度。近年全球农业基因组研究成果斐然，实现了从基础研究到生产应用的定向突破，且研究方向的相似性逐渐升高。未来全球农业基因组研究热点将转向关联性、多样性、准确性等更多维度、更高精度的研究，完整基因组、复杂基因组和泛基因组研究和技术的突破、基因芯片的研发仍具挑战。研究结果对基于数据的科学决策和科技创新具有指导意义。
