DataSheet_2_Research progress on Brassicaceae plants: a bibliometrics analysis.docx

The Brassicaceae is a worldwide family that produces ornamental flowers, edible vegetables, and oilseed plants, with high economic value in agriculture, horticulture, and landscaping. This study used the Web of Science core dataset and the CiteSpace bibliometric tool to quantitatively visualize the number of publications, authors, institutions, and countries of 3139 papers related to Brassicaceae plants from 2002 to 2022. The keywords and references were divided into two phases: Phase 1 (2002-2011) and Phase 2 (2012-2022) for quantitative and qualitative analysis. The results showed: An average annual publication volume of 149 articles, with an overall fluctuating upward trend; the research force was mainly led by Professor Ihsan A. Al-shehbaz from Missouri Botanical Garden; and the United States had the highest number of publications. In the first phase, research focused on the phylogeny of Brassicaceae plants, while the second phase delved into diverse research based on previous studies, research in areas such as polyploidy, molecular technique, physiology, and hyperaccumulator has been extended. Based on this research, we propounded some ideas for future studies on Brassicaceae plants and summarized the research gaps.

十字花科（Brassicaceae）是一类全球分布的植物科，涵盖观赏花卉、食用蔬菜与油料作物类群，在农业、园艺及园林绿化领域具备极高经济价值。本研究以Web of Science核心数据集（Web of Science Core Dataset）与文献计量工具CiteSpace为分析手段，对2002年至2022年间3139篇与十字花科植物相关的学术论文的发文量、作者、研究机构及发文国家进行量化可视化分析；并将该批论文的关键词与参考文献划分为两个阶段——第一阶段（2002-2011年）与第二阶段（2012-2022年）——分别开展定量与定性分析。研究结果显示：年均发文量达149篇，整体呈波动上升趋势；研究力量主要由密苏里植物园的Ihsan A. Al-shehbaz教授主导；美国的发文量位居全球首位。第一阶段的研究聚焦于十字花科植物的系统发育学，第二阶段则在前期研究基础上拓展了研究维度，在多倍体、分子技术、生理学及超富集植物（hyperaccumulator）等领域的研究均有所延伸。基于本研究结果，本研究针对十字花科植物的未来研究方向提出了若干设想，并梳理了当前研究的空白领域。
