Texto completoBarley yellow dwarf disease (BYDD) is an important cereal disease caused by a complex of viruses (B/CYDV, Luteoviridae) aphid-transmitted in a persisten manner. The BYDV-PAV species based on aphicid treatments two resistance genes deriving fro mThinopyrum intermedium have been itrogressed in wheat to produce Zhong ZH and TC14 lines. Those lines have been evaluated for their ability to limit the infection progression of BYDV-PAV isolates by monitoring viral infection. Both lines show partial resistance properties and could interfere with mechanisms of viral particles in plant. In other respects, durabilities of resistance of these lines have been analysed in laboratory conditions. A hundred serial passages enables a forced replication of one BYDV-PAV isolate in each line. Isolates resulting from passages on resistant hosts overcame partial resistance at passge 5 and induced increased damages when compared to reference isolates, both on susceptible and resistant hosts. These isolates have then been tested in natural conditions to assess the stability of these propoerties. Resuslts from a three-year field trial indicate that isolates issued from passages on Zhong ZH or on TC14 induce more severe yield losses than reference isolates. As a conclusion both resistance genes may be overcome. However their use in wheat breeding against BYDD may be pursued. Indeed, ecological conditions encountered by the virus in nature (obligatory host change) differ from those on the laboratory and could prevent the overcoming. Finally the association of both genes in one line could enable to obtaining of a stronger and more durable resistance than those they individually provide

Texto completoNew cultural practices against barley scald disease were proposed and some epidemiological characteristics of the fungal pathogen Rhynchosporium secalis (Oud. ) Davis, especially importance of seeds, assessed both directly showing its presence and indirectly by field trials. The first analysis method, a "classical" one, associated barley seeds disinfection with ethanol, sodium hypochlorite and bactericidal and fungicidal solution, before placing them on the elective ("barley") and selective medium (terramycine + iprodione + procymidone + 2,4 D). But the experiments were not adequatly successful. The second method, immunofluorescence, allowed routine analysis of seeds samples. Moreover, a higher specificity of immunsera was obtained by complex immunization procedures including different antigenic forms. The chemical treatments of seeds and sprayings of fungicides on the soil that were tested allowed estimation of the comparative importance of "seeds" and "soil" inoculum. They also demonstrated that such applications can be useful as cultural techniques. Lastly, varietal mixtures can be used as a strategy to limit disease spreading in the crop

Texto completoWheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) are among the main cereals cultivated worldwide due to their economic and social significance. However, their yield can drop by more than 40% when infected by the ascospore Zymoseptoria tritici, causing wheat septoria, and by Pyrenophora teres, which causes net blotch. Therefore, to reduce the use of pesticides, this project aimed to identify a strain that can significantly reduce the symptoms caused by these two pathogens. The strain Bacillus velezensis BE2 DSM115797 was chosen for its antifungal properties, both in vitro and in planta. An in-depth study of the mechanisms of action revealed that, when applied to the roots of wheat and barley, the bacterium significantly reduced leaf symptoms, inducing systemic resistance in the plant. Transcriptomic and metabolomic studies confirmed that the bacteria, once applied, did not trigger an immediate response in the plant. However, after a pathogenic infection, plants inoculated with the BE2 strain showed a more pronounced activation of their defense mechanisms, leading to a potentiating effect in the plant. At the bacterial level, a direct antagonism was also demonstrated with the identification of secondary metabolites that have antifungal effects on both fungi. Moreover, the production of these metabolites varied based on the presence of the pathogens

Texto completoThis project adopts an interdisciplinary approach to address the challenges posed by net blotch, a phytopathogenic disease caused by Pyrenophora teres, affecting barley (Hordeum vulgare L.) within the context of climate change. This disease is one of the most destructive, significantly reducing crop yields.In this work, a deep-learning model combining Cascade R-CNN and U-Net architectures was developed to quantify disease symptoms on barley leaves. The model achieved a 95% accuracy in lesion detection and demonstrated a particular effectiveness in identifying small, irregular lesions four days post-infection. This model was validated through classical measurements and PCR-based detection methods, providing a robust tool for automated disease management under real conditions.Additionally, a novel early detection method was developed based on k-mer analysis of P. teres genomes, leading to the design of primers and a TaqMan probe capable of detecting both P. teres f. sp. teres and P. teres f. sp. maculata before symptom onset. This detection before symptoms occurrence, validated through qPCR and ddPCR, is the first one in our knowledge. Thus, this approach represents a major breakthrough for net blotch management in barley and more largely for managing diseases in agricultural settings.In the context of climate change, projections revealed that annual mean temperature and precipitation during the coldest quarter are key factors influencing the future distribution of P. teres. Models predict a potential expansion of this pathogen to North America, Oceania, and Europe by 2040. Genomic analysis of hybrid strains showed an increased diversity of effectors and secondary metabolites, enhancing pathogen adaptabilityand virulence. Key effectors identified include Kex2, RCLR-like motifs, MoCDIP11, as well as ToxB, PIN_09941, MoCDIP8, and Nip1, highlighting the crucial role of genetic ecombination in the pathogenicity of hybrid strains.This study emphasizes the importance of integrating genomic tools, climate modeling, and biocontrol technologies to develop sustainable disease management strategies for phytopathogens in an evolving environment
