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 combination of plant genetic resistances and fungicides use. R- gene-based qualitative resistance durability limited due to gene-for-gene interactions with fungal avirulence ( Avr ) genes. Quantitative considered more durable but the mechanisms involved are not well documented. We hypothesize that genes in quantitative plant-pathogen similar. A bi-parental population Zymoseptoria tritici was inoculated on cultivar ‘Renan’ linkage analysis performed map QTL. Three pathogenicity QTL, Qzt-I05-1, Qzt-I05-6 Qzt-I07-13 , were mapped chromosomes 1, 6 13 Z. candidate gene chromosome selected based its effector-like characteristics. The cloned Agrobacterium tumefaciens -mediated transformation, pathology test assessed effect mutant strains ‘Renan’. This demonstrated be pathogenicity. By cloning newly annotated quantitative-effect effector-like, we underlying QTL can similar opens up previously probed possibility ‘gene-for-gene’ underlies only also this pathosystem.

Till death do us pair: Co-evolution of plant–necrotroph interactions

Current Opinion in Plant Biology, Год журнала: 2023, Номер 76, С. 102457 - 102457

Plants use programmed cell death as a potent defense response against biotrophic pathogens that require living host cells to thrive. However, can promote infection by necrotrophic pathogens. This discrepancy creates specific co-evolutionary dynamics in the interaction between plants and necrotrophs. Necrotrophic produce diverse death-inducing effectors act redundantly on several plant targets sometimes suppress immune responses an additional function. surface receptors recognize increase quantitative disease resistance, some of which evolved independently lineages. Co-evolution has shaped molecular mechanisms involved plant–necrotroph interactions into robust systems, relying degenerate multifunctional modules, general-purpose components, compartmentalized functioning.

Microbial Effectors: Key Determinants in Plant Health and Disease

Microorganisms, Год журнала: 2022, Номер 10(10), С. 1980 - 1980

Опубликована: Окт. 6, 2022

Effectors are small, secreted molecules that alter host cell structure and function, thereby facilitating infection or triggering a defense response. Effectoromics studies have focused on effectors in plant–pathogen interactions, where their contributions to virulence determined the plant host, i.e., whether effector induces resistance susceptibility disease. Effector from pathogenic microorganisms such as fungi, oomycetes bacteria major disease determinants. Interestingly, of non-pathogenic organisms endophytes display similar functions but different outcomes for health. Endophyte commonly aid establishment mutualistic interactions with contribute health through induction systemic against pathogens, while mainly debilitate plant’s immune response, resulting pathogens well tools be considered effectoromics development novel strategies management. This review aims present roles promotors host.
