Thousand cankers disease (TCD) is a new disease of black walnut (Juglans nigra L.) in the eastern United States. The disease is caused by the interaction of the aggressive bark beetle Pityophthorus juglandis Blackman and the canker-forming fungus, Geosmithia morbida M. Kolarik, E. Freeland, C. Utley & Tisserat, carried by the beetle. Other insects also colonize TCD-symptomatic trees and may als...
BACKGROUND Walnuts significantly decrease total and low-density lipoprotein cholesterol in normo- and hypercholesterolemic individuals. No study to date has evaluated the effects of walnuts on cholesterol efflux, the initial step in reverse cholesterol transport, in macrophage-derived foam cells (MDFC). The present study was conducted to investigate the mechanisms by which walnut oil affects ch...
BACKGROUND The prevalence of IgE reactivity against genuine walnut and hazelnut allergens is poorly defined. OBJECTIVE The IgE response to walnut and hazelnut was investigated in Italian patients with primary allergy to these nuts. METHODS Sera from 36 patients allergic to hazelnut and/or walnut, not reactive to PR-10, profilin, and LTP, underwent immunoblot analysis with extracts of both n...
During the past year, we collected walnut aphid parasitoids, !. pallidus, from 8 walnut orchards. Parasites from 2 sites were maintained as individual colonies, those from'the six other sites were pooled into one colony. These colonies and one started in 1985 from three sites were screened with Guthion. We found substantial variability in responses to Guthion by these colonies, which suggests t...
The reproductive fitness of seven isolates of Pratylenchus vulnus from different geographical areas and hosts was assessed in monoxenic cultures (carrot), and greenhouse cultures (plum, sour orange, and quince). The genetic makeup of the different isolates was compared by Random Amplified Polymorphic DNA (RAPD-PCR). The apple (PvAP-S) and apricot (PvAT-F) isolates reproduced less in monoxenic c...
In this research, the application of walnut shell ash, as an adsorbent for soybean oil bleaching, has been investigated. Therefore, neutralized soybean oil was bleached with 1 and 2% of walnut shell ash as well as commercial bleaching earth. Then, a series of chemical tests such as amounts of carotenoids, chlorophylls, peroxide value, and free fatty acid content of bleached oils and oil retenti...
The black walnut (Juglans nigra L.) is an underutilized fruit in the mid-hills of Nepal. However, the physico-chemical properties of Nepalese black walnut are almost unavailable in the literature. Four walnut growing districts namely Baitadi, Dadeldhura, Jumla and East Rukum selected and the black walnut collected at commercial maturity from the local markets. The physical properties w...
Analysis of genetic structure and differentiation using 12 microsatellite loci of six walnut populations, three each from the Greater Caucasus and the Talysh, revealed a moderate range of variation. The observed number of alleles ranged from 2 to 11 alleles with a mean of 5.6 alleles per locus. The populations differed significantly for the frequency and composition of alleles for ten out of tw...
