BACKGROUND Dietary strategies that help patients adhere to a weight reduction diet may increase the likelihood of weight loss maintenance and improved long-term health outcomes. Regular nut consumption has been associated with better weight management and less adiposity. The objective of this study was to compare the effects of a walnut-enriched reduced-energy diet to a standard reduced-energy-...

Homogeneity in azinphosmethyl resistance was assessed in males of a laboratory-selected (Select-H) and susceptible (Yolo) colony of Trioxys pallidus (Hymenoptera: Aphidiidae) using a time response assay. No evidence of heterogeneity within the two colonies was found. Reciprocal crosses between the Yolo and Select-19 colonies resulted in F1 females which exhibited a semidominant response to azin...

RFLP markers were used to investigate genetic diversity among California walnut (Juglans regia) cultivars and germplasm collected worldwide. Sixteen of 21 RFLP markers were polymorphic in the 48 walnut accessions tested. RFLP markers were useful for identifying walnut cultivars. All genotypes were heterozygous at ≈20% of the loci for both California and worldwide germplasm. California walnut ge...

The Persian walnut (Juglans regia L.) is one of the most valuable resources in Iran because of its multi benefits. The present study was conducted in Meshkin-Shahr in Ardabil province to investigate the important quantitative and qualitative characteristics of 31 walnut genotypes. Classification of genotypes was analyzed using the cluster method. The results showed that among selected walnut ge...

Crown gall of walnut (Juglans sp.), caused by the bacterium Agrobacterium tumefaciens, greatly impacts the CA walnut industry. To determine the genetic diversity of A. tumefaciens throughout the Central Valley of CA, we collected isolates from 12 walnut growing counties. A total of 340 A. tumefaciens biovar 1 isolates were collected and tested for the presence of the Ti plasmid by PCR; 267 isol...

Thousand cankers disease (TCD) is a newly recognized disease of various species of walnut (Juglans). Black walnut (Juglans nigra) is particularly susceptible to TCD and during the past decade it has devastated plantings of black walnut in most western states. In July 2010 thousand cankers disease was found over an extensive area around Knoxville, Tennessee, the first finding of TCD within the n...
