Expression and genetics of resistance to Septoria tritici in wheat
… (Triticum aestivum) to the leaf blotch pathogen Septoria tritici (anamorph of Mycosphaerella graminicola) was conducted to provide information on the inheritance and heritability of resistance, the occurrence of physiologic specialization in the pathogen, the components of resistance and …

Genetics of partial resistance of wheat to septoria tritici blotch
Septoria tritici blotch (STB), caused by the fungus Mycosphaerella graminicola, is the major foliar disease of wheat in many countries. Most resistance in wheat cultivars is partial resistance, which is polygenic, or oligogenic and non-specific to particular pathogen genotypes, and hence is …

Inoculation, Life Cycle and Host-Parasite Relationship of Septoria Tritici, Rob., on Triticum Species
Made available in DSpace on 2014-12-05T20:30:06Z (GMT). No. of bitstreams: 1 0018150.pdf: 4684618 bytes, checksum: 3cd65e7f451d885809799af1fbe2330a (MD5) Previous issue date: 1956

Disease escape in relation to a trade off between septoria tritici blotch and yield of wheat
Disease escape in relation to a trade off between septoria tritici blotch and yield of wheat. Zymoseptoria tritici, the fungus that causes Septoria tritici blotch (STB) of wheat, is spread by splash borne transfer from the base of the plant to the flag leaf. This project is on a potential new …

Pyramiding Disease Resistance Genes In Wheat (Triticum aestivum L.)
… to Fusarium head blight (FHB), leaf rust (Lr), Septoria tritici blotch (STB) and barley yellow dwarf virus (BYDV) in wheat. Two winter and two spring wheat cultivars were crossed and seven generations of spring wheat were developed in three years. Fifty percent of the F3 and 20% of the F5 …

Images radar des précipitations et durée d’humectation simulée pour l’évaluation des risques potentiels d’infection du blé d’hiver par la septoriose
… radar sur les périodes d’infection de Septoria tritici simulées par PROCULTURE a été évalué durant trois saisons culturales (2003, 2004 et 2005) par comparaison entre les données de sortie du modèle (alimenté par des estimations radar de précipitations horaires) et les estimations …

Effects of the Lr34 and Lr46 rust-resistance genes on other diseases of wheat
… these genes increased susceptibility to Septoria tritici blotch (STB), caused by Zymoseptoria tritici, in near-isogenic lines (NILs) of spring wheats Lal Bahadur (LB) and Avocet and mutant lines developed from LB, but not in an Lr34 NIL of Jupateco. A similar effect was observed in adult …

Responses of wheat to infection by Mycosphaerella graminicola
… pathogen Mycosphaerella graminicola causes septoria tritici blotch, the most important foliar disease of wheat in Europe. During a compatible interaction, host responses to infection allow the development of necrosis as a form of programmed cell death which appears to aid infection rather …

Identification and analysis of mechanisms involved in a broad-spectrum disease resistant mutant of the winter wheat cv. Guardian
… 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 (caused by the necrotroph Stagonosporum nodorum) and septoria tritici …

Understanding the molecular basis of Zymoseptoria tritici-wheat interactions
Zymoseptoria tritici is causal to one of the most devastating diseases of wheat, Septoria tritici blotch, STB, in Europe. An estimated 70% of fungicides deployed in Europe is for managing STB. Fundamental research has been undertaken with a focus on understanding the mechanistic basis of STB …

Evaluation des paramètres épidémiologiques des principales maladies cryptogamiques affectant les feuilles du blé d’hiver au Grand-Duché de Luxembourg : calibration et validation d’un modèle de prévision
… graminicola très connue sous le nom de Septoria tritici. Cette simulation se base sur le système Proculture développé par l’Unité de Phytopathologie de l’UCL. Ce système se démarque des systèmes d’avertissements classiques par sa prise en compte d’un module de croissance des feuilles et …
