Aggressiveness Variation in Czech Isolates of Erysiphe cichoracearum Pathotype AB1B2CCm
نویسندگان
چکیده
Introduction. Erysiphe cichoracearum /Ec/ is the predominating powdery mildew species on cucurbits in the Czech Republic (5). Its occurrence and spreading on cucurbits can be influenced not only by virulence, but also by aggressiveness of isolates within natural pathogen populations. Both forms of pathogenicity have an impact on plant cultivation and protection and should be considered in resistance breeding. The purpose of this study was to describe the aggressiveness variation within a group of Ec isolates of a known pathotype.

Powdery mildew caused by Erysiphe necator, is one of the most economically damaging diseases of grapevine throughout the world. This is the first molecular biology study on this fungus in Iran. The aims of the present study were (a) to analyse genetic diversity between isolates of E. necator fungus in four main grape production regions in Iran, i. e., Qazvin, Alamoot, Takestan and Shahriar and ...

In this study, we cloned a new chitinase gene, EuCHIT2, from Eucommia ulmoides Oliver (E. ulmoides) using rapid amplification of cDNA ends (RACE) technology and constructed an overexpression vector, pSH-35S-EuCHIT2, to introduce it into tobacco (Nicotiana tabacum cv. Xanthi). Resistance to Erysiphe cichoracearum de Candolle (E.cichoracearum DC) and molecular mechanisms in the transgenic tobacco...

متن کاملRapid identification of genetic variation and pathotype of Leptosphaeria maculans by random amplified polymorphic DNA assay.
Canadian isolates of Leptosphaeria maculans, the causal agent of blackleg of crucifers, were examined for genetic relatedness by the random amplified polymorphic DNA assay. DNA polymorphisms amplified with random decamer primers were used to distinguish three groups of isolates. Group 1 contained all isolates of the virulent pathotype, group 2 contained isolates of the avirulent pathotype from ...
