Exploiting rice diversity to uncover durable and broad-spectrum resistance
… respectively. This study aims to identify novel, broad-spectrum and durable sources of resistance to BB and BLS, and to pinpoint potential candidate genes for further characterization. We screened an indica rice Multi-parent Advanced Generation Inter-Cross (MAGIC) population, a novel mapping …

Characterisation of a maize mutant deficient in antifungal kauralexin accumulation
… kauralexins and zealexins, play a role in fungal resistance. It has previously been shown that maize lines inoculated with either F. verticillioides or C. zeina induces kauralexin and zealexin accumulation. In addition, kauralexin metabolite accumulation and candidate kauralexin biosynthetic gene …

Basidiospore infection of Austropuccinia psidii and resistance ofopen-pollinated Eucalyptus globulus families to rust and Teratosphaeria Leaf Disease
… Successful control requires the availability of resistance sources, a comprehensive understanding of pathogen population diversity, and the selection of resistant genotypes through inoculations under controlled environmental conditions. This study aimed to assess the resistance of native families …

Influence of salicylate and abscisic acid on the resisitance of tomato to biotrophic and necrotrophic pathogens
… defence pathway activated both basal and induced resistance against B. cinerea but not against O. neolycopersici. The reverse effects were observed in tobacco, indicating that plant defence responses activated by the SA-dependent pathway depend on the specific host–pathogen system. Another plant …

Primary care antimicrobial stewardship: Impact on prescribing and resistance
<b>Background: </b>Antimicrobial resistance is an increasing world-wide public health concern, with antimicrobial use described as one of the main drivers. Most antimicrobial prescribing occurs in primary care which is therefore a key target for antimicrobial stewardship. This thesis examines …

Induced disease resistance elicited by acibenzolar-S-methyl and plant growth-promoting rhizobacteria in tobacco (Nicotiana tabacum L.)
Active disease resistance in plants is induced during the pathogen infection process that triggers multiple defense-related genes to establish broad-spectrum resistance. Several biotic and abiotic agents can mimic natural induced resistance (IR), categorized as systemic acquired (SAR) or induced …

Identification and analysis of mechanisms involved in a broad-spectrum disease resistant mutant of the winter wheat cv. Guardian
… wheat (Triticum aestivum) cv. Guardian exhibits broad-spectrum resistance to powdery mildew (Blumeria graminis f. sp. tritici), yellow rust (Puccinia striiformis f. sp. tritici), and leaf rust (Puccinia recondita f. sp. tritici), along with partial resistance to stagnonospora nodorum blotch …

Identifying loci conferring quantitative disease resistance in sorghum and maize against fungal foliar pathogens
… which hosts defend themselves against pathogens. Broadly disease resistance can be split into qualitative and quantitative resistance. In qualitative resistance the presence of a single resistance gene (R gene) confers complete resistance against the pathogen. R proteins can interact directly as …

AN INTEGRATED APPROACH TO THE DEVELOPMENT OF RESISTANCE TO COMMON BACTERIAL BLIGHT IN COMMON BEAN (PHASEOLUS VULGARIS)
… can reduce yields by up to 45 %. Breeding for resistance is the most sustainable control strategy, yet resistance is quantitative and influenced by pathogen diversity. Most known quantitative trait loci (QTLs) derive from Mesoamerican germplasm, leaving Andean market classes such as cranberry …

New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens = New molecular mechanisms of Arabidopsis thaliana resistance to necrotrophic pathogens
The resistance of plants to necrotrophic fungi is genetically complex and depends on the interplay of different signalling pathways. To get further insights on the mechanisms controlling plant defence to this type of pathogens, we have explored the relevance of additional, uncharacterized molecular …
