Special Issue "Fungal Disease Management and Mycotoxin Prevention in Cereals"
Deadline for manuscript submissions: 31 October 2021.
Interests: identification, characterization and recombination-based transfer of alien Triticeae genes into cultivated wheat, targeting resistance to wheat diseases (e.g., rusts, powdery mildew, scab) and abiotic stresses, quality attributes, and yield-related traits; physiological and metabolic responses of wheat-alien genotypes towards biotic and abiotic stresses; sustainable wheat production through development of pre-breeding and breeding lines carrying traits derived from related wild species; organization of cereal genomes (wheat and related species) by genetic, cytogenetic and comparative genomic approaches
Interests: molecular plant–pathogen interaction; identification and characterization of cell wall degrading enzymes (CWDEs) produced by pathogenic fungi and bacteria; interaction of CWDEs and their plant inhibitors; virulence factors of necrotrophic fungi; identification and activity of natural molecules against plant pathogens; mycotoxin detoxification in plants
Interests: genetic and physiological basis of wheat yield and disease resistance; chromosome engineering and exploitation of alien genetic variability for wheat improvement; metabolic and molecular characterization of plant response to pathogens; spike fertility tolerance to abiotic and biotic stresses
Fungal diseases of grain cereals, including primarily wheat, maize, rice, and barley, cause worldwide substantial reduction of grain yield and quality, which negatively affects the harvest, storage, and subsequent marketability of the products. A further threat is represented by mycotoxins, produced by some widespread pathogens (e.g., Fusarium spp.), which determine a variety of adverse effects (from acute poisoning to long-term effects such as immune deficiency and cancer) to both human and livestock health. Regulations on maximum mycotoxins levels have been established worldwide to protect consumers from their harmful effects, and the public concern on food safety extends to excessive and inappropriate use of pesticides, whose residues are likewise dangerous for consumers, as well as the environment.
An increasing and more demanding world population, coupled with environmental issues, including climate changes, altogether pose as an essential goal the search for new and sustainable strategies to mitigate the many negative impacts of widespread fungal diseases on cereal crops. In this view, the Special Issue aims at collecting the results of recent advances in fungal disease management, addressing different topics, such as:
- Management of agronomic practices;
- Integrated disease management strategies, including use of fungicides, natural molecules with antifungal activity or biological control agents;
- Model-driven decision support systems;
- Identification and characterization of plant mechanisms involved in resistance against fungal pathogens or mycotoxin detoxification;
- Identification and utilization of genetic resources for disease resistance;
- Integrated control measures of fungal infections and mycotoxin accumulation at post-harvest stage.

1. How Maize Seed Systems Can Control Mycotoxigenic Fungi: A Perspective
P. C. Biemond, T. J. Stomph, P. Lava Kumar, and P. C. Struik
Abstract: Mycotoxins are fungal produced toxins threating human health in developing countries. Consumption of contaminated maize can cause cancer or even sudden death. Mycotoxigenic fungi infection is a requisite for mycotoxin production. This perspective assesses opportunities to prevent mycotoxigenic fungi infection in maize seed, as maize seed health proves to be essential to prevent transgenerational transmission of the infection. A case study of Nigeria showed that all farmer-produced, seed company and foundation seed samples were heavily infected. A schematic overview of the formal and informal seed system is presented to analyse fungi infection and mycotoxin contamination in the maize value chain, and to set criteria for successful control. We recommend an integrated approach to control mycotoxigenic fungi infection, including resistant varieties and other control methods, with an important role for seed systems.
2. A Two-Year Field Experiment for the Integrated Management of Bread and Durum Wheat Fungal Diseases in Central Italy

Abstract: Integrated disease management plays a key role for obtaining safe and sustainable wheat productions. At this purpose, a two-year (2018/19 and 2019/20) field trial was carried out to evaluate 7 bread and 8 durum wheat recently developed and commercially interesting varieties as well as the efficacy of the most recent wheat fungicides (including different modes of action: quinone-outside inhibitors, QoI; succinate dehydrogenase inhibitors, SDHI; demethylation inhibitors, DMI) towards fungal diseases. The experiment was carried out at the experimental station FIELDLAB of Papiano (Perugia, Umbria, Central Italy). All fungal diseases were evaluated under natural inoculum pressure with the exception of Fusarium Head Blight (FHB) for which artificial inoculation with a highly virulent Fusarium culmorum deoxynivalenol (DON)-producer strain was performed at the full anthesis stage (BBCH65). Fungicides were sprayed at two application timings corresponding to fully extended flag leaf (BBCH39) and full anthesis (BBCH65). Phytosanitary conditions of the tested varieties were monitored across their entire crop cycle; the incidence of different fungal diseases was visually assessed. Other parameters such as grains production (t/ha), protein content (%) and hectolitre weight (kg/hL) were also determined. Finally, DON accumulation (μg/kg) in the grains was quantified by the ELISA method. Significant differences were observed among the different wheat varieties both in terms of grains production and DON accumulation. In the two experimental years, each characterized by very different climatic conditions, fungicide treatments showed a high efficacy in controlling the observed fungal diseases (septoria tritici blotch, yellow and brown rusts and FHB). The obtained results highlight as varietal choice and the correct use of fungicides play a crucial role in the integrated management of wheat fungal diseases and DON contamination in the grains.
