“…The Fusarium species most commonly reported from maize and from sorghum are G. moniliformis and G. thapsina, respectively (18,21,24). While both of these species have been collected from other crops, they appear to be most common on their respective crop hosts and may represent aggressive, and at least partially specialized, pathogen popula- G. intermedia is often viewed as a generalist, as it has been recovered from a broad range of agricultural hosts that includes asparagus, banana, maize, mangos, millet, pine, rice, sorghum, and tobacco (21).…”

Fusarium species from agricultural crops have been well studied with respect to toxin production and genetic diversity, while similar studies of communities from nonagricultural plants are much more limited. We examined 72 Fusarium isolates from a native North American tallgrass prairie and found that Gibberella intermedia (Fusarium proliferatum), Gibberella moniliformis (Fusarium verticillioides), and Gibberella konza (Fusarium konzum) dominated. Gibberella thapsina (Fusarium thapsinum) and Gibberella subglutinans (Fusarium subglutinans) also were recovered, as were seven isolates that could not be assigned to any previously described species on the basis of either morphological or molecular characters. In general, isolates from the prairie grasses produced the same toxins in quantities similar to those produced by isolates of the same species recovered from agricultural hosts. The G. konza isolates produce little or no fumonisins (up to 120 g/g by one strain), and variable but generally low to moderate amounts of beauvericin (4 to 320 g/g) and fusaproliferin (50 to 540 g/g). Toxicity to Artemia salina larvae within most species was correlated with the concentration of either beauvericin or fusaproliferin produced. Organic isolates from some cultures of G. moniliformis were highly toxic towards A. salina even though they produced little, if any, beauvericin or fusaproliferin. Thus, additional potentially toxigenic compounds may be synthesized by G. moniliformis strains isolated from prairie grasses. The Fusarium community from these grasses appears to contain some species not found in surrounding agricultural communities, including some that probably are undescribed, and could be capable of serving as a reservoir for strains of potential agricultural importance.

“…Strains were scored as fertile if they produced ascospores in one or more tests. Selected nonfertile strains were tested further on carrot agar with tester strains of MP-F (Fusarium thapsinum) (12), and with various female fertile field strains and ascospore progeny of MP-C and MP-D that were identified in the initial mating population tests. The MP-A tester strains were M-3125 and M-3120, the MP-C tester strains were M-6883 and M-6884, the MP-D tester strains were M-6992 and M-6993, and the MP-F tester strains were M-6563 and M-6564 (11,13,15).…”

Infection of cereal grains with Fusarium species can cause contamination with mycotoxins that affect human and animal health. To determine the potential for mycotoxin contamination, we isolated Fusarium species from samples of rice seeds that were collected in 1997 on farms in the foothills of the Nepal Himalaya. The predominant Fusarium species in surface-disinfested seeds with husks were species of the Gibberella fujikuroi complex, including G. fujikuroi mating population A (anamorph, Fusarium verticillioides), G. fujikuroi mating population C (anamorph, Fusarium fujikuroi), and G. fujikuroi mating population D (anamorph, Fusarium proliferatum). The widespread occurrence of mating population D suggests that its role in the complex symptoms of bakanae disease of rice may be significant. Other common species were Gibberella zeae (anamorph, Fusarium graminearum) and Fusarium semitectum, with Fusarium acuminatum, Fusarium anguioides, Fusarium avenaceum, Fusarium chlamydosporum, Fusarium equiseti, and Fusarium oxysporum occasionally present. Strains of mating population C produced beauvericin, moniliformin, and gibberellic acid, but little or no fumonisin, whereas strains of mating population D produced beauvericin, fumonisin, and, usually, moniliformin, but no gibberellic acid. Some strains of G. zeae produced the 8-ketotrichothecene nivalenol, whereas others produced deoxynivalenol. Despite the occurrence of fumonisin-producing strains of mating population D, and of 8-ketotrichothecene-producing strains of G. zeae, Nepalese rice showed no detectable contamination with these mycotoxins. Effective traditional practices for grain drying and storage may prevent contamination of Nepalese rice with Fusarium mycotoxins.

“…subglutinans, including stalk and root rots, seedling blight, pokkah boeng and grain mould (Tarr, 1962). The taxonomy of these two species has changed dramatically over the past 25 years (Klittich & Leslie, 1992, Klittich et al, 1997, Leslie et al, 2005a, Marasas et al, 2001). Fusarium moniliforme sensu lato has been segregated into a number of species based on several factors such as the preference of host (Jardine & Leslie, 1992, Klittich & Leslie, 1992, Tesso et al, 2010, ability to synthesize mycotoxins (Tesso et al, 2010), and benomyl and hygromycin sensitivity (Tesso et al, 2010).…”

“…According to Leslie and Summerell (2006), in the last 20 years at least four additional chainforming species have been described within the Section Liseola, including F. globosum, F. thapsinum, F. nisikadoi, and F. miscanthi, as well as some species that do not form chains (Leslie & Summerell, 2006, Rheeder et al, 1996, Klittich et al, 1997, Nirenberg & Aoki, 1997, Gams et al, 1999.…”

“…Historically, F. moniliforme sensu lato was thought to be the causal agent of Fusarium stalk rot worldwide, however recent changes in taxonomy have split the species into a number of different species. Since then, several studies have proven F. thapsinum to be the dominant sorghum stalk rot pathogen in most areas worldwide (Klittich et al, 1997, Leslie & Marasas, 2002. A study by Petrovic et al (2009) in two sorghum crops in eastern Australia found both F. thapsinum and F. andiyazi to be the most prevalent species in stalk rot affected plants.…”
