Walnut Blight: Genetic Variation in English Walnut in Response to Inoculation with Xanthomonas Campestris Pv. Juglandis
This was the second year of a study which evaluated the genetic variation among English walnut germplasm in response to infection by Xanthomonas campestris pv. juqlandis (Xcj), the bacterium which causes the disease walnut blight. Immature leaves and nuts of 10 walnut accessions representing the breadth of currently available germplasm were inoculated. Leaves were scored for disease severity at...
متن کاملIn Vitro and in Vivo Neuroprotective Effects of Walnut (Juglandis Semen) in Models of Parkinson’s Disease
Monoamine oxidase (MAO) catalyzes the oxidative deamination of monoamines including dopamine (DA). MAO expression is elevated in Parkinson's disease (PD). An increase in MAO activity is closely related to age, and this may induce neuronal degeneration in the brain due to oxidative stress. MAO (and particularly monoamine oxidase B (MAO-B)) participates in the generation of reactive oxygen specie...

متن کاملPhylogeography of the Walnut Twig Beetle, Pityophthorus juglandis, the Vector of Thousand Cankers Disease in North American Walnut Trees
Thousand cankers disease (TCD) of walnut trees (Juglans spp.) results from aggressive feeding in the phloem by the walnut twig beetle (WTB), Pityophthorus juglandis, accompanied by inoculation of its galleries with a pathogenic fungus, Geosmithia morbida. In 1960, WTB was only known from four U.S. counties (in Arizona, California, and New Mexico), but the species has now (2014) invaded over 115...
