Phenotypic and genetic resistance to Septoria blotch disease in European wheat varieties. [PDF]

Plant Genome
Abstract Zymoseptoria tritici, the causal agent of Septoria tritici blotch (STB), poses a critical threat to wheat (Triticum aestivum L.) production in temperate Europe, underscoring the need for durable genetic resistance. Here, we screened 151 winter wheat varieties at the seedling stage using a mixed inoculum of five virulent isolates.

A Meta-Analysis Reveals That the Protective Role of Silicon in Grasses Against Fungal Pathogens Depends on Infection Mechanism. [PDF]

Plant Cell Environ
ABSTRACT Pathogen infection drives plant community structure and constrains global agricultural productivity. Silicon (Si) improves resistance to abiotic and herbivory stress, particularly in grasses, but relatively little attention has addressed Si‐mediated resistance to pathogens, nor has it tested how this varies according to the type of plant and ...

Identification of resistance sources and genomic regions regulating spot blotch resistance in Asian bread wheat (Triticum aestivum L.) via genome-wide association study. [PDF]

Plant Genome
Abstract Spot blotch (SB), caused by Bipolaris sorokiniana, is a major yield‐limiting disease of wheat (Triticum aestivum L.) in the warm, humid agroclimatic zones of South Asia. The development of resistant cultivars through molecular approaches offers a sustainable strategy for managing this disease.

Mycobiome Simplification in Wheat Is Associated With the Pathogen Parastagonospora nodorum. [PDF]

Mol Ecol
ABSTRACT Plant mycobiomes are essential to plant health, yet their assembly under biotic stressors such as pathogen infection remains poorly understood. Plant pathogens can influence microbial community composition through direct antagonism and suppression of host immune responses, potentially altering mycobiome composition in ways that could affect ...

A new method to measure EC₅₀ reveals cultivar-specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici. [PDF]

Pest Manag Sci
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Genetics and breeding for resistance against four leaf spot diseases in wheat (Triticum aestivum L.)

Frontiers in Plant Science, 2023
In wheat, major yield losses are caused by a variety of diseases including rusts, spike diseases, leaf spot and root diseases. The genetics of resistance against all these diseases have been studied in great detail and utilized for breeding resistant ...

Some Agronomic Properties of Winter Wheat Genotypes Grown at Different Locations in Croatia

Agriculture, 2023
A collection of fourteen winter wheat accessions was evaluated to describe agro-morphological traits over a two-year study at four locations. Changes in grain yield, test weight, and plant height were related to differences in growing seasons, locations,

Antifungal alternation can be beneficial for durability but at the cost of generalist resistance

Communications Biology, 2023
Alternation results in slower acquisition of fungicide resistance in Zymoseptoria tritici, the causative agent of septoria leaf blotch in wheat.
