A Bibliometric Analysis of Genome-wide Association Study (GWAS) and Sorghum (Sorghum bicolor L) Based on Web of Science Using VOS Viewer

Abstract

The basic principle of GWAS is to integrate genotype and phenotype data through general linear models or mixed linear models (MLM). Genome-wide association study (GWAS) is an efficient method to discover genomic regions associated with traits of interest and has been successfully implemented in various crops, including sorghum. Bibliometric analysis is a method that quantitatively evaluates scientific research by measuring the knowledge conveyed through scientific publications within a specific field. A total of 227 scholarly articles on sorghum and genome-wide association studies (GWAS) were examined within the Web of Science database, spanning the years 2000 to 2022. All of the articles, written by 1117 authors from 27 publishers, 347 institutes, and 48 countries and published in 91 journals, were written in English. The five most prominent journals in the field were identified as Theoretical and Applied Genetics (8.37%), G3 Genes Genomes Genetics (7.04%), Frontiers in Plant Science (6.60%), Plant Genome (6.60%), and Plant Physiology (4.40%), with each having published more than 10 papers. The five countries that ranked highest in terms of paper publications were the United States, the People's Republic of China, India, Australia, and Germany. According to the available data, the leading publishers in the field were Springer Nature, Wiley, Oxford University Press, Frontiers Media SA, and MDPI. The authors, who have published the highest number of papers, exceeding twelve in quantity, are Morris GP, Kresovich S, Hu ZB, Perumal R, and Upadhyaya HD. The set of keywords was partitioned into six distinct clusters, each corresponding to a unique area of the research query. Visualizations provide a means of exploring the current state of a scientific field or discipline and can also suggest potential future directions. The identification of primary research concepts and areas in this study may prove beneficial for forthcoming research endeavors and policy-making processes concerning the enhancement of sorghum.
