Abstract Plant resistance genes play a critical role in enhancing crop immunity against various biotic stresses, such as pathogens, nematodes, and insects, safeguarding global agricultural productivity. A collection of plant resistance genes identified between 1992 and 2017 has been reported previously. To provide an updated overview of advances in research on plant resistance genes, we sorted out the mapped, identified, and cloned plant resistance genes reported from 2018 to the present. Data analyses revealed a total of 101 plant resistance genes reported since 2018, mainly from economically important crops (rice and wheat) and the model plant Arabidopsis thaliana , with a main focus on fungi, bacteria, and viruses. We subsequently conducted a bibliometric analysis of 9533 publications on plant resistance genes from the Web of Science core collection between 2007 and 2024. The number of publications increased from 334 in 2007 to 937 in 2024, significantly contributed by the institutions of the United States and China. Both the United States Department of Agriculture and the Chinese Academy of Agricultural Sciences are the top two institutions contributing to these publications. The top three journals in terms of publication volume are The Plant Cell, Journal of Integrative Plant Biology, and Plant Science. In addition, the leading journals Nature and Science published approximately 5% and 9% of these publications, respectively. Keywords analysis identified four primary research clusters: molecular mechanisms of plant resistance genes, plant immunity, wheat-specific resistance, and rice disease management. This study provides valuable insights into research trends, collaboration, and high-impact areas, serving as a resource for advancing plant resistance strategies to ensure global food security.
