Powdery mildews are phytopathogens whose growth and reproduction are entirely dependent
on living plant cells. The molecular basis of this life-style, obligate biotrophy, remains …

… significantly reduced foliar PPO activity while S-18 and S-28 showed significantly increased
PPO activity compared to NT plants. At leaf node 4, S-18 and S-28 possessed the highest …

In the present study we screened the progeny of Vitis vinifera × V. romanetii populations
segregating for resistance to powdery mildew and determined the presence of a single, …

… PCR conditions were: 30 s at 95C followed by 35 cycles of 45 s 94C, 45 s at specific
primer T m , 45 s at 72C; followed by 1 h at 72C. Detection by capillary electrophoresis was …

… R-gene with PCD-mediated resistance is not novel. Our goal in communicating these
results quickly and directly to the grape community is to encourage breeders, pathologists, and …

… against powdery mildews is well documented in small grains but, in other crops such as
grapevine, controlled analysis of host–pathogen interactions on resistant plants is uncommon. In …

Genotyping microarrays are widely used for genetic mapping, but in high-diversity
organisms, the quality of SNP calls can be diminished by genetic variation near the assayed …

… Vitis vinifera is the primary scion variety grown around the world and is highly susceptible
to downy mildew. R genes are accessible in American and Asiatic species of Vitis, which …

Polyphenol oxidases (PPOs), which catalyze the oxidation of phenolics to quinones, have
been reported to confer resistance to Pseudomonas syringae and are assumed to be involved …

Downy mildew (Plasmopara viticola) and anthracnose (Sphaceloma ampelinum) are two of
the major diseases of most grapevine (Vitis vinifera L.) cultivars grown in Thailand. Therefore…
