Deep population structure linked to host vernalization requirement in the barley net blotch fungal pathogen.

Invasive fungal pathogens pose a substantial threat to widely cultivated crop species, owing to their capacity to adapt to new hosts and new environmental conditions. Gaining insights into the demographic history of these pathogens and unravelling the mechanisms driving coevolutionary processes are crucial for developing durably effective disease management programmes. is a significant fungal pathogen of barley, consisting of two lineages, Ptt and Ptm, with global distributions and demographic histories reflecting barley domestication and spread.

Quantitative and qualitative plant-pathogen interactions call upon similar pathogenicity genes with a spectrum of effects.

Septoria leaf blotch is a foliar wheat disease controlled by a combination of plant genetic resistances and fungicides use. gene-based qualitative resistance durability is limited due to gene-for-gene interactions with fungal avirulence () genes. Quantitative resistance is considered more durable but the mechanisms involved are not well documented.

Complete Genome Sequences of : A Resource for Studying a Damaging Flax Pathogen.

Fungal genus causes diseases in a wide range of plants. Here, we report the first genome sequences of two strains of , the causal agent of the pasmo disease of flax (). The genome of the first strain, SE15195, was fully assembled in 16 chromosomes, while 35 unitigs were obtained for a second strain, SE14017.

First report of barley virus G infecting winter barley (Hordeum vulgare L.) in France.

As part of a cereals virome project high throughput sequencing (HTS)-based viral indexing was performed on plants with symptoms of barley yellow dwarf disease collected in June (2017-2020) in the main French cereals production areas. Total RNAs from 32 individual plants were purified (RNeasy Plant Mini Kit, Qiagen, Courtaboeuf, France) and Illumina sequenced (2x150 nt) following ribodepletion (Genewiz-Azenta, Leipzig, Germany). Following quality trimming, reads for each sample were de novo assembled (CLC Genomics Workbench 21, Qiagen) [1] and contigs annotated by BlastX analysis.

Wheat Stem Rust Back in Europe: Diversity, Prevalence and Impact on Host Resistance.

The objective of this study was to investigate the re-emergence of a previously important crop pathogen in Europe, f.sp. causing wheat stem rust.
