Summary: We report a novel narnavirus, PsV5, from the devastating wheat stripe rust fungus. The PsV5 genome contains two predicted ORFs, an RdRp and a reverse-frame ORF with unknown function. Overexpression of PsV5 increases susceptibility to Pst in wheat and enhances virulence in Fusarium graminearum. These findings provide insights for sustainable wheat rust disease control and expand our understanding of virosphere diversity.

Summary: In this study, a Bln gene (TaBln4) was isolated from wheat infected by Puccinia striiformis. TaBln4 expression was upregulated in response to infection by a virulent race of the pathogen, but not in response to an avirulent race. It was also regulated by hormones and abiotic stresses. Knockdown of TaBln4 inhibited colonization of the virulent race and increased the accumulation of H2O2 and hypersensitive responses. TaBln4 interacted with calmodulin and negatively regulated wheat resistance to the pathogen in a reactive oxygen species and hypersensitive response-dependent manner.

Summary: This study identified a wheat RNA-binding protein 1 (TaRBP1) that acts as a negative regulator in response to infection by Puccinia striiformis f. sp. tritici (Pst). Knockdown of TaRBP1 resulted in enhanced resistance to Pst, suggesting its role in plant defence. TaRBP1 interacted with TaGLTP and prevented its degradation in plants. The findings reveal a novel susceptible mechanism by which plants fine-tune their defence responses during Pst infection.

Summary: Reports on the effectiveness of Fusarium head blight (FHB) control measures vary by region, and the combined effects of abiotic and biotic factors on FHB are not fully understood. The study suggests that ploughing may increase the risk of less frequent toxigenic Fusarium species occurrence.

Summary: In this study, species- and trichothecene-specific primers were used to monitor the F. graminearum species complex (FGSC) originating from Serbia. The primers were not specific for 11% of the F. graminearum population, but were effective in multilocus genotyping of Tri7, Tri3, and Tri5 genes. Alternaria spp. had a significant influence on grain infection with F. graminearum, indicating the need for further investigation.

Summary: Wheat stripe rust caused by the fungal pathogen Puccinia striiformis f. sp. tritici poses a constant threat to wheat production in South Africa. Genomic-based analyses revealed genetic diversity and relationships between South African Pst isolates and isolates from East Africa, Pakistan, the UK, and France. There is a critical need for continuous surveillance to monitor the introduction and transmission of Pst isolates to prevent future rust epidemics.

Summary: The utilization of production systems with reduced chemical input renewed the interest in Ustilago nuda and Pyrenophora graminea. The investigations of seed fungicide treatments are more related to their efficacy than to their contribution to yield gain. The data were collected from research and development trials on fungicide efficacy against U. nuda and P. graminea conducted from 2014 to 2020 in Serbia. Statistical modeling techniques were used to analyze the data and it was found that abiotic factors such as temperature, rainfall, and humidity significantly influenced the occurrence of both pathogens and yield loss. The study also revealed that fungicidal treatments did not have a stable contribution to yield gain in the seven-year period.

Summary: Tracking the distribution of Fusarium species and changes in toxin production is important for managing Fusarium head blight (FHB). This study characterized members of the Fusarium graminearum species complex (FGSC) and investigated their associations with cereal crop species, seeding time, type of cultivation, and chemotype grouping. The study found that different cereal crop species were associated with different FGSC isolates. Species-specific primers and trichothecene genotyping primer sets were effective in identifying Fusarium species and genotypes. Intercropping systems showed potential in controlling FHB.

Summary: In the past ten years, the RenSeq protocol has been proven to be a powerful tool for studying disease resistance in plants. However, the lack of a unified workflow and the need for bioinformatics expertise have posed challenges for reproducibility and version control. In response, we have developed HISS, a user-friendly and easily customizable approach for identifying disease resistance genes in plants.

Summary: Widespread usage of intercropping systems has been limited due to a lack of understanding about the key factors influencing intercrop performance. Using general linear modeling, we examined the effects of different cropping systems on yield, thousand kernel weight (TKW), and crude protein of cereal crops under the same agro-ecological conditions. Our study found that intercropping cultivation can reduce yield variations caused by extreme climatic conditions. The occurrence of leaf rust and powdery mildew was highly influenced by the type of cultivation. Additionally, the relationship between pathogenic infection levels and yield performance was complex and depended on the cultivar's potential yield.

Summary: This study evaluated the relationship between Fusarium head blight (FHB) traits, thousand-kernel weight (TKW), and yield in 40 commercial winter wheat cultivars. The results showed that FHB index was more strongly related to yield, while Fusarium-damaged kernels (FDK) had a stronger relationship with TKW. The relationship between these traits also varied with the resistance/susceptibility of the cultivars. The study suggests the need for more efficient and reliable investigations on grain resistance to FHB under pathogen pressure.
