Fusarium graminearum is ranked among the ten most dangerous fungal pathogens that affect agro-ecosystems. It causes floral diseases in small grains including wheat, barley and oats, as well as summer crops such as maize and rice. Infected kernels are light-weight and may be contaminated with mycotoxins of concern to human and animal health, mainly trichothecenes and zearalenone. The increased availability of F. graminearum strains collected worldwide, from different hosts/substrates, together with advances in taxonomy based on genealogical concordance, led to the recognition of species, as part of the Fusarium graminearum species complex (FGSC), during the 2000s. Surveys of FGSC strains have been conducted and reported worldwide for different crops/substrates, with strains being accurately identified to species, including novel species within the complex, using DNA barcoding methods. In addition, the potential to produce mycotoxins, mainly B-trichothecenes, is determined using either chemical methods or, more commonly, time and cost-effective PCR-based assays that target portions of genes of the trichothecene biosynthetic (TRI) cluster. We conducted a systematic review of peer-reviewed studies reporting lineages/species within FGSC. Two main data tables were created. The first, contained data at the article level including bibliographic, scientometric, geographic, methodological (ID methods), host surveyed and FGSC species. A second data table contained information at the strain level such as article, code(s), host/substrate, year, geographical coordinates, species and trichothecene genotype. In this talk, bibliographic and scientometric analyses of the data obtained from 77 peer-reviewed articles authored by 323 authors and published in 27 journals that matched the criteria (as of August 2018) will be presented. A summary of the data at the strain level for a total of 14,553 catalogued strains will be presented as part of a website, the global FGSC database. The interactive dashboard (accessible at: https://github.com/emdelponte/FGSC) allows for searches, summarization and mapping of strains according to several criteria including article, country, host, species and trichothecene genotype. The FGSC database may be useful for guiding future surveys and exploring factors associated with species distribution such as climate and land use. This work is supported by CNPq and Mycokey project.
