a plant viral vector engineered from an in vivo infectious clone of zucchini yellow mosaic virus(zymv) was used to express the human interferon-gamma (inf-γ) in planta. the inf-γ gene was in frame inserted between the p1 and hc-pro orfs of the zymv vector. the infectious activity of the vector was approved by rubbing the plasmid on chenopodium quino a and observing local lesions. individual les...

We monitored pollen-mediated transgene dissemination from commercial transgenic squash CZW-3 into its wild relative Cucurbita pepo ssp. ovifera var. texana (C. texana). Transgenic squash CZW-3 expresses the neomycin phosphotransferase II (nptII) gene and the coat protein (CP) genes of Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV), and Watermelon mosaic virus (WMV); thereby, i...

Ali, A., Mohammad, O., and Khattab, A. 2012. Distribution of viruses infecting cucurbit crops and isolation of potential new virus-like sequences from weeds in Oklahoma. Plant Dis. 96:243-248. Field surveys were conducted from 2008 to 2010 to detect and determine the incidence of viruses in the major cucurbit-growing areas of Oklahoma. In total, 1,049 symptomatic leaf samples (890 from cucurbit...

AIMS The purpose of this study is to determine the degree of satisfaction of users of the Cancer Information Point section of the Library for Patients (CIP-LP), active since 1998 at the National Cancer Institute of Aviano, Italy. The CIP-LP is based on a skilled intermediary, adequate informative material and a specific location, within the Scientific Library of the Institute. PATIENTS AND ME...

Virus-resistant transgenic squash are grown throughout the United States and much of Mexico and it is likely that the virus-resistant transgene (VRT) has been introduced to wild populations repeatedly. The evolutionary fate of any resistance gene in wild populations and its environmental impacts depend upon trade-offs between the costs and benefits of the resistance gene. In a 3-year field stud...

Genomic components of the begomovirus causing yellow mosaic disease (YMD) in soybean in Delhi were cloned, sequenced and infectivity proved. Nucleotide sequence analysis of the virus isolate revealed more than 89% identity with Mungbean yellow mosaic India virus (MYMIV) and therefore it is designated as soybean isolate of MYMIV (MYMIV-[Sb]). Total nucleotide and predicted amino acid sequence an...
