The fungus Zymoseptoria tritici is a strictly apoplastic, host-specific pathogen of wheat leaves and causal agent of septoria tritici blotch (STB) disease. All other plants are considered nonhosts, but the mechanism of nonhost resistance (NHR) to Z. tritici has not been addressed previously. We sought to develop Nicotiana benthamiana as a system to study NHR against Z. tritici. Fluorescence mic...
Biological characterization of fenpicoxamid, a new fungicide with utility in cereals and other crops
BACKGROUND The development of novel highly efficacious fungicides that lack cross-resistance is extremely desirable. Fenpicoxamid (Inatreq™ active) possesses these characteristics and is a member of a novel picolinamide class of fungicides derived from the antifungal natural product UK-2A. RESULTS Fenpicoxamid strongly inhibited in vitro growth of several ascomycete fungi, including Zymosepto...
Magnaporthaceae is a family of ascomycetes that includes three fungi of great economic importance: Magnaporthe oryzae, Gaeumannomyces graminis var. tritici, and Magnaporthe poae. These three fungi cause widespread disease and loss in cereal and grass crops, including rice blast disease (M. oryzae), take-all disease in wheat and other grasses (G. graminis), and summer patch disease in turf grass...
Host specialization is a key evolutionary process for the diversification and emergence of new pathogens. However, the molecular determinants of host range are poorly understood. Smut fungi are biotrophic pathogens that have distinct and narrow host ranges based on largely unknown genetic determinants. Hence, we aimed to expand comparative genomics analyses of smut fungi by including more speci...
We examine the contribution of next generation sequencing (NGS) to our understanding of the interaction between the fungal pathogen Zymoseptoria tritici and its wheat host. Recent interspecific whole genome comparisons between Z. tritici and its close relatives provide evidence that Z. tritici has undergone strong adaptive evolution, which is attributed to specialization by Z. tritici on wheat....
The hemibiotrophic fungus Zymoseptoria tritici causes Septoria tritici blotch disease of wheat (Triticum aestivum). Pathogen reproduction on wheat occurs without cell penetration, suggesting that dynamic and intimate intercellular communication occurs between fungus and plant throughout the disease cycle. We used deep RNA sequencing and metabolomics to investigate the physiology of plant and pa...
به منظور شناسایی قارچ¬های همراه بذر برنج 30 نمونه بذر برنج جمع¬آوری شده از مناطق مختلف استان کهگیلویه و بویراحمد (یاسوج، دنا، گچساران، باشت، چرام و دهدشت) با استفاده از روش¬های قرار دادن روی محیط کشت، قرار دادن روی کاغذ صافی مرطوب، بلاتر انجمادی و شستشوی بذر مورد مطالعه قرار گرفت. همچنین آزمون اثبات بیماری¬زایی گونه¬های قارچی جدا شده روی ارقام برنج غالب تحت کشت در این استان (چمپا، گرده، لنجان و...
1. High competitive ability is believed to be an important characteristic of invasive species. Many animal studies have compared the competitive ability of invasive species with a native species that is being displaced, but few have looked at systems where an invasive species has failed to establish itself. These types of studies are important to determine if competition is relevant not only to...
B. Moerschbacher, K. H. Kogel, U. Noll, and H. J. Reisener Institut für Biologie III der RW TH Aachen, W orringer Weg, D-5100 Aachen, Bundesrepublik Deutschland Z. Naturforsch. 41c, 830—838 (1986); received April 4/May 5, 1986 Triticum aestivum, Puccinia graminis f. sp. tritici, Hypersensitive Response, Lignification, Elicitor Several biotic and abiotic elicitors of the hypersensitive reaction ...
The fungus Zymoseptoria tritici is the causal agent of Septoria Tritici Blotch (STB) disease of wheat leaves. Zymoseptoria tritici secretes many functionally uncharacterized effector proteins during infection. Here, we characterized a secreted ribonuclease (Zt6) with an unusual biphasic expression pattern. Transient expression systems were used to characterize Zt6, and mutants thereof, in both ...
