Abstract:

In order to deeply understand the research progress and development trend of root exudates, this paper took the literature related to root exudates from 2002 to 2022 in the Web of Science core collection database as the data source and used the bibliometric method to visualize the annual number of papers, the cooperative relationship between high-yield countries, the distribution of journals, the co-citation of literature and high-frequency keywords with the help of software VOSviewer and CiteSpace. At the same time, the main research contents in different research stages were analyzed. The results showed that the annual number of publications in the field of root exudates research in the past 20 years was on the rise, and it had attracted more and more attention in the international scope. China and the United States had close cooperative relationships, and the highest number of collaborative publications. Chinese Academy of Sciences and Colorado State University had been committed to research in this field and had made outstanding contributions. Plant and Soil and Soil Biology & Biochemistry were the two journals with the largest number of papers published in this field. The core topics of root exudates research were ‘ecosystem’, ‘rhizosphere microbiome’, ‘organic acid’, ‘gene’, ‘stress’ and ‘plant fitness’. The main research contents of root exudates in different research stages were signal transduction-nutrient acquisition- allelopathy- phytoremediation- plant and microbial interaction. More detailed researches on revealing the interaction mechanism between plants and rhizosphere microorganisms at the molecular level, the regulatory function and molecular mechanism of root exudates and rhizosphere microorganisms in plant growth may become new research hotspots in the future.
