Abstract:

This study aims to systematically understand the research trends and hotspots of plant disease resistance genes in China. Taking CiteSpace as the tool, the core journals of CNKI databases were used to carry out quantitative and visual analysis of literature related to plant disease resistance genes published from 1991 to 2021. The results showed that the number of publications on plant disease resistance genes increased year by year on the whole. The Institute of Plant Protection of the Chinese Academy of Agricultural Sciences had the highest number of publications among all research institutes, with a total of 86. It was the the journal of Scientia Agricultura Sinica that published the most literature, with 87 publications. With 38 articles, Liu Daqun, from Hebei Agricultural University, published the most. Based on the co-occurrence keyword analysis, the highest frequency keyword was “disease resistance genes”, which appeared 226 times in total. In the analysis of emergent words, the keyword with the highest intensity was “avirulence genes” (9.707). There are several hotspots for plant disease resistance genes, including the prevention and control of crop diseases, the technical means of disease resistance gene research, and the chemical components related to disease resistance.

Key words: plant disease resistance genes, CiteSpace, visual analysis, bibliometrics, knowledge map
