Reaction of ten peach and ten nectarine cultivars to powdery mildew

Karbalaei Khiavi H, Pirayesh A, Seyed Masoumi SY, Khabbaz Jolfaei H (2021). Reaction of ten peach and ten nectarine cultivars to powdery mildew. Plant Pathology Science 10(1):1-13.      Doi: 10.2982/PPS.10.1.1.   Introduction: Powdery mildew caused by Podosphaera pannosa is one of the most important diseases of peaches and nectarines worldwide, including Iran. The aim of this research was to ...

Correlation of defense gene induction defects with powdery mildew susceptibility in Arabidopsis enhanced disease susceptibility mutants.

We investigated the relative importance of specific Arabidopsis thaliana genes in conferring resistance to bacterial versus fungal pathogens. We first developed a pathosystem involving the infection of Arabidopsis accession Columbia with a virulent isolate of the obligate biotrophic fungal pathogen Erysiphe orontii. E. orontii elicited the accumulation of mRNAs corresponding to the defense-rela...

Efficiency of resistance genes in wheat to powdery mildew in some centers of disease incidence in Iran

Wheat powdery mildew caused by fungal pathogen Blumeria graminis f.sp. tritici is a destructive wheat disease, occurring in regions with cool and humid climates. In order to investigate the changes in pathogenicity of the disease and to identify the effective genetic source of resistance, a total of 29 wheat genotypes with different resistance major genes (Pm) were studied in two hotspots of Go...

Fruit Yield, Quality Variables, and Powdery Mildew Susceptibility of Galia Melon Cultivars Grown in a Passively Ventilated Greenhouse

Galia muskmelon (Cucumis melo L. var. Reticulatus Ser.) is an F1 hybrid known for exceptional fruit flavor. Since introduction to the market in 1973, the original ‘Galia’ has become a trade name for look-alike cultivars. Some ‘Galia’-type cultivars are firmer, ship well, and may be less susceptible to powdery mildew [Podosphaera xanthii (Px) (syn. Sphaerotheca fulignea)] than a true ‘Galia’, bu...
