Zucchini (Cucurbita pepo subsp. pepo) is a seasonal vegetable with high nutritional and medical values. Many useful properties of this fruit are attributed to bioactive compounds. Zucchini fruits ("Yellow" and "Light Green" varieties) and four distinctive components (lutein, β-carotene, zeaxanthin and dehydroascorbic acid) were selected. Firstly, the lutein, β-carotene, zeaxanthin and dehydroas...

Localized Competition, Multimarket Operation and Collusive Behavior by Frank Verboven This paper studies collusive behavior in a repeated oligopoly model with localized competition. Private information about the rivals' past actions naturally arises from this product market structure. The resulting communication problems imply that firms should adopt strategies with sufficiently lenient punishm...

A generic assay to detect and partially characterize unknown viruses from plants was developed. Proteins extracted from virus-infected and uninfected plants were separated in one dimension by SDS polyacrylamide gel electrophoresis. Differentially expressed protein bands were eluted after trypsin digestion and resulting peptide fragments separated according to their mass by matrix-assisted laser...

Field experiments were conducted in Maryland to investigate the influence of sunn hemp cover cropping in conjunction with organic and synthetic fertilizers on the nematode community in a zucchini cropping system. Two field treatments, zucchini planted into a sunn hemp living and surface mulch (SH) and zucchini planted into bare-ground (BG) were established during three field seasons from 2009 t...

The main goal of our study was to determine whether biosynthesized silver nanoparticles (SNPs) could be used as a novel antibacterial material in order control soft rot vegetables. Exudates from oak fruit were the green synthesis SNPs. Postharvest disease vegetables has resulted significant crop losses all over globe. Because managing Pectobacterium carotovorum subsp. (Pcc), causal agent diseas...

BACKGROUND & AIMS Previous studies showed that (1) breastfeeding and (2) higher food variety early in weaning can increase acceptance of new foods for the next few days. Here we measure, in two European regions, effects of breast or formula feeding and experience with different levels of vegetable variety early in weaning on new food acceptance during two months following the start of weaning. ...

The infectious full-length cDNA clone of zucchini yellow mosaic virus (ZYMV) isolate PA (pZYMV-PA), which was isolated from pumpkin, was constructed by utilizing viral transcription and processing signals to produce infectious in vivo transcripts. Simple rub-inoculation of plasmid DNAs of pZYMV-PA was successful to cause infection of zucchini plants (Cucurbita pepo L.). We further engineered th...

The Drosophila mutant turnip was initially isolated based on poor learning performance (Quinn, W.G., Sziber, P.P., and Booker, R. (1979) Nature 277, 212-214). Here we show that turnip is dramatically reduced in protein kinase C (PKC) activity. In addition, turnip flies are deficient in phosphorylation of a 76-kDa head membrane protein (hereafter pp76) which is a major substrate for protein kina...

Analysis of overnight carrot broth culture using the BD GeneOhm StrepB assay (carrot broth-enhanced PCR) yields increased sensitivity compared to that of carrot broth culture alone for the detection of Streptococcus agalactiae. We investigated the prospect of reducing the carrot broth incubation time prior to PCR performance. In vitro experimentation demonstrated that carrot broth-enhanced PCR ...
