Cotton (Gossypium hirsutum L.) belongs to the malvaceas family and is grown in all regions of Brazil. According to data from the Brazilian Association of Cotton Producers, Brazil occupies 4th place in the ranking of cotton production according to the 18/19 harvest. Because of this importance, this review aimed to carry out a bibliometric survey on cotton oil and flour and their applications. For this, a bibliometric analysis was carried out relating cotton, oil and flour in the Scopus and Web of Science databases in the years 1989-2019, and subsequently, the Web of Science data were analyzed using the VOSviewer program. The results showed that there were a total of 1525 research and reviews articles in the Scopus and Web of Science databases in the last three decades, and, based on the entire analysis, it was noticed that the studies of the last three decades are focused on separation area and biofuels, as well as that the Republic of China stands out among the most cited countries besides its universities. According to these results, it can be concluded that the Republic of China has a lot of influence in studies with cotton and more research is needed to use cotton and its derivatives in the food industry.

In this study, we summarized the evolution of scientific research about fungus Phakopsora pachyrhizi Sydow & Sydow affecting soybean [Glycine max (L.) Merrill]. We retrieved research articles from the Thomson Reuters Web of Science database that reported studies of the Asian soybean rust (ASR) from 1945 to 2018. We applied the scientometric analysis of the temporal trends of authors, journals, research partnerships, and resistance genes to ASR. Several studies aiming to understand fungal etiology, testing, or improve strategies to control the pathogen were developed. The temporal trends in publications showed an increase in the number of publications between 2005 and 2013. This is directly related to the dissemination of ASR in South and later North America, which facilitates field research and an increase in grant opportunities. The USA had the highest number of published articles (42%), followed by Brazil, Germany, Japan, and Argentina. The leading organizations associated with these publications are from Brazil and the USA. 19% of articles pertaining to ASR were published in the journal Plant Disease. Our results also showed that among the seven dominant genes identified for resistance to ASR, Rpp1, and Rpp2 are the most studied. Several countries, institutions, and plant scientists are deeply involved in ASR research and have been making efforts to control this disease and ensure food security worldwide.
