Summary: Field trials were conducted to investigate the relationship between Asian corn borer infestation, Fusarium verticillioides infection, yield loss, and fumonisin contamination in maize. The results showed that infestation by the Asian corn borer significantly promoted F. verticillioides infection and grain fumonisin levels. These findings suggest that Asian corn borer infestation can lead to severe quality degradation and yield loss of maize, with potential threats to food and feed security.

Summary: The study found that under the same environmental conditions, there was higher activation of lipid signaling systems in hybrid H22 compared to H21, suggesting that less susceptible hybrids may have other pathways to limit fumonisin B accumulation. The results highlight the crucial role of oxylipin and sphingolipid signaling in modulating the complex maize response to F. verticillioides infection.

Summary: The commercial and sanitary qualities of cereals determine the final application and destination of the grain. The cultivation area of sorghum has been increasing in Italy and is often adjacent to maize fields, leading to the risk of sharing mycotoxigenic fungi such as Fusarium verticillioides. This study explores the commonalities and differences in fungal physiology and plant growth parameters between F. verticillioides strains from maize and sorghum.

Summary: In this study, the antifungal activity of seven Azotobacter species against Fusarium verticillioides was tested. The Azotobacter strains exhibited significant growth inhibition of F. verticillioides and degradation of its fumonisin. Secondary metabolites were isolated and characterized from the Azotobacter strains for the first time.

Summary: Field experiments were conducted to evaluate the roles of two corn borers, Asian corn borer (ACB), Ostrinia furnacalis and yellow peach moth (YPM), Conogethes punctiferalis, in Fusarium verticillioides infection using green fluorescent protein (GFP) as a marker. The study found that larvae of ACB and YPM significantly increased F. verticillioides infection in maize ears, and that manual injuries and insect control measures also affected the spread of the fungus. The presence of corn borers and the severity of F. verticillioides infection were strongly correlated with the level of fumonisin, a mycotoxin produced by the fungus, in maize kernels.

Summary: Ellagic acid and isoeugenol were identified as the most effective natural phenolic compounds for inhibiting fungal growth and reducing toxin production in maize contaminated with Fusarium verticillioides. Proper dosages of these compounds are crucial to prevent conditions that promote mycotoxin biosynthesis. These phenolic compounds modulate biosynthesis at the transcription level in different ways depending on the strain.

Summary: This study evaluated the contamination of hidden fumonisins in the main corn-based products consumed in Brazil. The results showed that all analyzed samples contained free fumonisins, but none exceeded the maximum tolerated level. Hidden fumonisins were also present in all samples, with concentrations 1.1-2.7 times higher than free fumonisins.

Summary: In this study, the localization of key enzymes involved in fumonisin biosynthesis pathway in Fusarium verticillioides was examined. Results showed that these enzymes co-localized with the vacuole. Disruption of vacuole associated proteins and microtubule assembly resulted in reduced fumonisin biosynthesis.

Summary: Malaysia has started cultivating grain corn locally to reduce import dependency for animal feed industries. Fungal isolates were collected from two pioneer grain corn farms, revealing a predominance of Fusarium verticillioides, with several other fungal species present, some of which could produce mycotoxins in vitro. This research provides a baseline for further studies on fungal contamination and mycotoxin accumulation in Malaysian grain corn agroecosystems.

Summary: The study aimed to evaluate the impact of nitrogen rates and ear inoculation treatments on maize production and quality parameters. Results showed that nitrogen levels significantly influenced the incidence of Fusarium spp. in maize, while ear inoculation treatments had a greater impact on maize quality parameters.

Summary: The research demonstrates that fumonisin B1 increases the aggressiveness of Fusarium proliferatum on banana fruit and inhibits the defense ability of banana fruit by affecting enzyme activities and cell death-related genes. This leads to a reduction in disease resistance of banana fruit and acceleration of cell death, possibly through altering hydrogen peroxide content. The study sheds light on the potential virulence factor role of fumonisins in modulating fruit defense response.

Summary: The interaction between Fusarium graminearum (FG) and Fusarium verticillioides (FV) in plants is influenced by mycotoxins. FG stimulates the growth of FV while FV suppresses the growth of FG. Fumonisins act as interference competition agents, while trichothecenes have no role in the interaction. FG stimulates FV growth by secreting hydrolases and may also affect plant defense. The biological function of fumonisin production in planta is to protect kernels shed on the ground before competitors become established.

Summary: Maize and other cereals are the most contaminated commodities in Africa. Although some countries have reported low levels of fumonisins, overall, most countries' maize is contaminated with fumonisins, with high levels detected in some countries.

Summary: The study examined the effect of different carbon sources on secondary metabolite biosynthesis in Fusarium verticillioides submerged cultures. It was found that the biosynthesis of useful metabolites was highest in cultures with fructose, lactose, and xylose, while the biosynthesis of harmful mycotoxins fumonisins was lowest in these carbon sources.
