Abstract: Bacteria is the main part of plant rhizosphere community, with high diversities and activities. They are divided into 2%-5% beneficial bacteria, 8%-15% pathogens and 80%-90% neutral bacteria. Plant growth promoting rhizobacteria (PGPR) selected from beneficial bacteria observed the function of promoting plant growth and preventing soil-borne diseases, which have become a research hotspot in soil science. So the aims were to review the research situation on PGPR, and to develop more efficient, long-term and safe utilization of PGPR in future. A bibliometric analysis by using CiteSpace, VOSviewer and HistCite was used to count the number of publications and their distributions in contributor countries, disciplines, publishing journals and hotspots in PGPR field based on Web of Science database. ① India, China, Pakistan and the United States were the major contributors of academic publications in this field, and cooperated closely with each other. ② Research in this field attracted growing attention worldwide between 2000 to 2022, and mainly categories of the publications were plant science and microbiology. ③ "Frontiers in Microbiology", "Frontiers in Plant Science" and "Plant and Soil" were the top 3 journals in the PGPR field, and key literatures mainly consisted of PGPR growth promotion, stress resistance and soil pollution remediation. ④ The future research trend focused mainly on the interaction among PGPR, indigenous microorganisms and plants, as well as efficient application of PGPR. The bibliometric analysis results indicated that "Azospirillum", "Mycorrhizal Fungi", "Biological Control", "Nitrogen Fixation" became current hotspots of PGPR research. With the rapid development of multi-omics, the knowledge of PGPR have been greatly expended. It is of great significance to develop more efficient, long-term and safe utilization of PGPR in future.
