Study of maize endophytes worldwide-analyzing and mapping by bibliometric approach

Abstract

Abstract No global summary of maize endophyte publication exists. It’s hard to elaborate on global data because the provided information is localized. This study examined maize endophyte research and its future insight. Six hundred-three papers related to the topic were downloaded from Scopus. Parameters were computed using Excel 2016, whereas bibliometric analysis used VOSviewer. Co-occurrence, co-authorship, and citation were the three primary types of analysis. Kolmogorov-Smirnov determined the author’s Lotka’s Law productivity. This study found that the cumulative number of publications followed a linear model from 1966 to 1991; however, later, the model followed an exponential curve. The most comprehensive research on maize endophytic topics is in Agricultural and Biological Sciences (34.3%). The US published 203 documents, followed by China and Brazil. The most published author is Bacon CW, who has published 23 papers. The distribution of the author’s productivity conforms to Lotka’s Law. The bibliometric map showed fungal, bacterial, and endophyte microbiology clusters. The result showed that the study on maize endophytic fungi was smaller than bacterial species. Bacillus sp. and Enterobacter sp. are the popular studied bacteria endophytes, while Beauveria bassiana dominates fungal. In addition, future research trends will concentrate on “fungi endophytes” and “effect on seed mycorrhiza.”
