“…Notes : Fusarium meridionale was originally known from the Southern Hemisphere, but is now known to have a global distribution ( O’Donnell et al 2004 , Farr & Rossman 2022 ). To date, this species has been reported as pathogens of maize ear rot, maize stalk rot, wheat scab and rice spikelet rot ( Zhang et al 2014b , 2016 , Dong et al 2020a ). Herein we newly record this species from wheat in China.…”

Fusarium species are important cereal pathogens that cause severe production losses to major cereal crops such as maize, rice, and wheat. However, the causal agents of Fusarium diseases on cereals have not been well documented because of the difficulty in species identification and the debates surrounding generic and species concepts. In this study, we used a citizen science initiative to investigate diseased cereal crops (maize, rice, wheat) from 250 locations, covering the major cereal-growing regions in China. A total of 2 020 Fusarium strains were isolated from 315 diseased samples. Employing multi-locus phylogeny and morphological features, the above strains were identified to 43 species, including eight novel species that are described in this paper. A world checklist of cereal-associated Fusarium species is provided, with 39 and 52 new records updated for the world and China, respectively. Notably, 56 % of samples collected in this study were observed to have co-infections of more than one Fusarium species, and the detailed associations are discussed. Following Koch’s postulates, 18 species were first confirmed as pathogens of maize stalk rot in this study. Furthermore, a high-confidence species tree was constructed in this study based on 1 001 homologous loci of 228 assembled genomes (40 genomes were sequenced and provided in this study), which supported the “narrow” generic concept of Fusarium (= Gibberella). This study represents one of the most comprehensive surveys of cereal Fusarium diseases to date. It significantly improves our understanding of the global diversity and distribution of cereal-associated Fusarium species, as well as largely clarifies the phylogenetic relationships within the genus.

“…A total of 26,644 isolates identified to species level were reported by the 123 peerreviewed studies. The number of strains per study ranged from one (Dong et al 2020) to 4,062 from a continent-wide survey (Kelly et al 2015). The mean number of strains per study was 218.4, but half of the studies included at least 62 strains (median).…”

Fusarium graminearum is ranked among the five most destructive fungal pathogens that affect agroecosystems. It causes floral diseases in small grain cereals including wheat, barley and oats, as well as summer crops such as maize and rice. We conducted a systematic review of peer-reviewed studies reporting species within the Fusarium graminearum species complex (FGSC) by creating two main data tables. The first contained data at the article level including bibliographic, geographic, methodological (ID methods), host of origin and species, while the second data table contained information at the strain level such as publication, isolate code(s), host/substrate, year of isolation, geographical coordinates, species and trichothecene genotype. Analyses of the bibliographic data obtained from 123 publications from 2000 to 2021 by 498 unique authors and published in 40 journals are summarized. We describe the frequency of species and chemotypes for 16,274 strains for which geographical information was available, either provided as raw data or extracted from the publications, and sampled across six continents and 32 countries. The database and interactive interface are publicly available allowing for searches, summarization and mapping of strains according to several criteria including article, country, host, species and trichothecene genotype. The database will be updated continuously and should be useful for guiding future surveys and exploring factors associated with species distribution such as climate and land use. Authors are encouraged to submit data at the strain level to the database, which is accessible at https://fgsc.netlify.app/.
