Fusarium stalk and ear rot disease did not only cause significant losses of yield but also produced mycotoxins that are harmful to animals and human. This study was conducted to elucidate three major mycotoxins i.e. fumonisin B1 (FUMB1), moniliformin (MON), and beauvericin (BEA) produced by the Fusarium spp. isolated from corn showing typical stalk and ear rot symptoms in Indonesia, Malaysia and Thailand. Twenty selected strains of Fusarium species in Gibberella fujikuroi species complex i.e. F.verticillioides, F. proliferatum, F. subglutinans, and F. konzum were analyzed for production of the three mycotoxins by using an Ultra Performance Liquid Chromatography (UPLC).  All strains of F. verticillioides and F. proliferatum produced FUMB1 at high levelsand MON at low levels. Many strains of F. verticillioides (67%) and F. proliferatum (50%) did not produce BEA while the others produced BEA at low levels. Two strains of F. subglutinans did not produce FUMB1 but produced MON at low levels. One strain of F. subglutinans produced BEA and the other one did not produce the toxin.  Two strains of F. konzum produced both MON and BEA at low levels but only one strain produced FUMB1 at a low level. These mycotoxins have not been reported from Fusarium spp. in Gibberella fujikuroi species complex isolated form stalk and ear rot diseases of corn in these areas. Therefore, concerted efforts must be made to educate all stake holders about the presence and health hazards of these mycotoxins.

ABSTRACT Gibberella xylarioides Heim & Saccas (presumed anamorph, Fusarium xylarioides Steyaert) is the causal agent of coffee wilt disease, an economically important tracheomycosis in Africa. In vitro crosses carried out with Congolese, Ugandan, and Tanzanian single-ascospore/conidial isolates originating from diseased Coffea canephora/excelsa demonstrated a heterothallic mating system, controlled by a single locus with two alleles, MAT-1 and MAT-2. Compatible isolates produced fertile perithecia within 2 to 8 weeks after mating. Mating type (MAT) was characterized by PCR with primer pairs previously developed for the Gibberella fujikuroi species complex (GFC) and for Fusarium oxysporum. All strains analyzed were morphologically identical and corresponded to Booth's description of the “female” F. xylarioides strain. Based on crossing results and MAT-2/translation elongation 1-α (tef) sequence data, G. xylarioides, as currently understood, is demonstrated to encompass at least three “groups”: G. xylarioides sensu strictu Ia, defined hitherto by two “historical” West African strains originating from the severe 1930s to 1950s epidemic (CBS 25852 and CBS 74979); G. xylarioides sensu strictu Ib, defined by two “historical” Central African lowland strains (DSMZ 62457 and ATCC 15664); and G. xylarioides sensu lato II, containing Congolese, Ugandan, and Tanzanian C. canephora/excelsa isolates. Infertility of crosses between the coffee wilt pathogen and known GFC mating populations demonstrates that G. xylarioides sensu lato constitutes a new biological species within the G. fujikuroi complex. MUCL 44532/MUCL 43887 and MUCL 35223/MUCL 44549 are proposed as G. xylarioides sensu lato II MAT-1/MAT-2 reference mating type tester strains.

Systemic Infections

Sorghum grain, valuable for feed, food, and bioenergy, can be colonized by several Fusarium spp.; therefore, it was of interest to identify possible sources of conidia. Analysis of air and soil samples provided evidence for the presence of propagules from Fusarium genotypes that may cause grain infections. Soil population estimates of members of the Gibberella fujikuroi species complex, that includes sorghum pathogens and other Fusarium spp., suggested that adequate inoculum for systemic infections was present. Conidia in air samples within two sorghum fields were collected by passive trapping for 2 years. Subsampled Fusarium isolates indicated that numbers of G. fujikuroi increased from anthesis through maturity, which coincides with grain development stages vulnerable to Fusarium spp. Genotyping using translation elongation factor 1-α gene sequences revealed that spore trap isolates included members of G. fujikuroi that are sorghum pathogens: Fusarium thapsinum, F. verticillioides, F. proliferatum, and F. andiyazi. Also detected were F. graminearum, F. subglutinans, and several F. incarnatum-F. equiseti species complex haplotypes that colonize sorghum asymptomatically. All commonly found grain colonizers were detected from air samples in this study.
