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.

ABSTRACT Black rot caused by hemibiotrophic Xanthomonas campestris pv. ( Xcc ) is a great problem in crucifer crop production. Various host responses are activated upon attack; however, their roles black resistance remain ambiguous. In this study, highly of plants was achieved applying field‐screened systemic resistance‐eliciting Bacillus velezensis strain 37‐1. The contributions 37‐1‐altered to were then investigated Arabidopsis . Hypersensitive response and hydrogen peroxide accumulation demonstrated beneficial for infection using nrg1 rbohd mutants, histochemical staining against cell death reactive oxygen species, detection antioxidant enzyme activity RT‐qPCR assay. By contrast, salicylic acid proven essential suppression NahG transformant, mutants impaired defence hormone synthesis signalling pathway, Additionally, both isochorismate synthase phenylalanine ammonia‐lyase pathways biosynthesis found be involved These findings improve the knowledge crucial fighting off

Stem canker of Zanthoxylum bungeanum is a destructive forest disease, caused by Fusarium zanthoxyli, poses serious threat to the cultivation Z. bungeanum. The lack research on effector proteins in F. zanthoxyli has severely limited our understanding molecular interactions between and bungeanum, resulting insufficient effective control technologies for this disease. In study, total 137 (FzEPs) were predicted characterized based whole genome with an average length 215 amino acids, 8 cysteine residues, weight 23.06 kD. Besides, phylogenetic evolution, conserved motifs, domains annotation information all effectors comprehensively demonstrated. Moreover, transcriptomic analysis indicated that 24 genes significantly upregulated early infection stages which was confirmed RT-qPCR. Following, DEGs cloned transiently over-expressed leaves tobacco evaluate their effects plant's innate immunity. It found FzEP94 FzEP123 induced pronounced programmed cell death (PCD), callose deposition, reactive oxygen species (ROS) burst leaves, whereas FzEP83 FzEP93 suppressed PCD INF1, accompanied less accumulation ROS burst. we systematically functionally analyzed successfully identifying four can impact immune response plants. These findings enhance protein functions offer valuable insights future
