Article Synopsis
- A new quantitative trait locus (QTL), QSnb.nmbu-2AS, was identified in both winter and spring wheat, which can enhance breeding efforts for resistance to Septoria nodorum blotch (SNB) caused by the pathogen Parastagonospora nodorum.
- This QTL showed consistent resistance across multiple years and is rare in current Nordic wheat cultivars, emphasizing its potential for future breeding programs.
- The study suggests that using marker-assisted selection to stack resistant alleles could effectively improve SNB resistance in wheat varieties.
Plants and fungi emit volatile organic compounds (VOCs) that are either constitutively produced or are produced in response to changes in their physico-chemical status. We hypothesized that these chemical signals could be utilized as diagnostic tools for plant diseases. VOCs from several common wheat pathogens in pure culture (, , , , and ) were collected and compared among isolates of the same fungus, between pathogens from different species, and between pathogens causing different disease groups [Fusarium head blight (FHB) and Septoria nodorum blotch (SNB)].

- Wheat plants face threats from various pests and diseases, and this study is the first to explore the interaction between aphids and the fungus causing septoria nodorum blotch (SNB).
- Researchers conducted experiments to assess aphid preferences and reproduction on both infected (SNB+) and healthy (SNB-) wheat plants, as well as the impact of aphid presence on SNB infection rates.
- Findings revealed that aphids preferred and reproduced more on healthy wheat leaves, while previous aphid infestation made wheat plants more susceptible to SNB, highlighting the need for new strategies in integrated pest management (IPM).
The fungus is a narrow host range necrotrophic fungal pathogen that causes Septoria nodorum blotch (SNB) of cereals, most notably wheat (). Although commonly observed on wheat seedlings, infection has the greatest effect on the adult crop. It results in leaf blotch, which limits photosynthesis and thus crop growth and yield.
