Grain at Risk: Confronting Wheat Blast and Global Food Security

Magnaporthe oryzae Triticum (MoT), a recently discovered wheat blast fungus, posing an imminent threat to the world's wheat output. The fungus responsible for rice blast disease is a unique, exceptionally diversified lineage of M. oryzae. Wheat head infection can lead to 100% yield losses, causing spike bleaching, resulting in no grain or shrivelled grain with low test weight. An integrated management program is recommended for managing the dangerous wheat disease due to limited fungicide efficiency and the absence of resistant types. Understanding the disease's epidemiology and developing a real-time disease monitoring system is crucial for effective management. Understanding the fungus's infection biology and interactions with wheat plants is also essential. Genome-based methods are used to identify MoT field isolates, utilizing unique disease markers, allowing for evolutionary change due to the significant genetic and pathotype variety in the fungal population.
