BACKGROUND The potato psyllid is a serious pest of potatoes. Sampling plans on potatoes for the potato psyllid have yet to be developed, thus the authors' objectives were (1) to determine the most efficient within-plant sampling unit, (2) to determine the spatial dispersion of potato psyllids in potato fields and (3) to develop a binomial sequential sampling plan for this pest. RESULTS Signif...
Serological Relationship between Potato Paracrinkle Virus, Potato Virus S and Carnation Latent Virus
The cucumber mosaic virus (CMV) 2b viral suppressor of RNA silencing (VSR) inhibits host responses to jasmonic acid (JA), a chemical signal regulating resistance to insects. Previous experiments with a CMV subgroup IA strain and its 2b gene deletion mutant suggested that VSRs might neutralize aphid (Myzus persicae) resistance by inhibiting JA-regulated gene expression. To further investigate th...
Post-transcriptional gene silencing (PTGS) of a green fluorescent protein (GFP) transgene is suppressed in Nicotiana benthamiana plants infected with potato virus Y (PVY) or with cucumber mosaic virus (CMV), but not in plants infected with potato virus X (PVX). By expressing PVY and CMV-encoded proteins in a PVX vector we have shown that the viral suppressors of gene silencing are the HCPro of ...
منطقه فریدن با سطح زیر کشت بیش از 11 هزار هکتار یکی از مراکز مهم تولید سیب زمینی بذری در ایران است که هر ساله مقادیر زیادی از محصول تولید شده در این منطقه به عنوان غده های بذری در سایر نقاط کشور نیز مورد استفاده قرار می گیرد و سالانه بیش از 25 هزار تن غده های عاری از ویروس برای کاشت نیاز دارد. در این پژوهش به منظور بررسی روند آلودگی های ویروسی در کاشت غده های بذری سیب زمینی عاری از ویروس و مدت ...
BACKGROUND The effectiveness of the universal school-based alcohol prevention program "Unge & Rus" [Youth & Alcohol] was tested by an independent research group. The program aims to prevent alcohol use and to change adolescents' alcohol-related attitudes. The main outcome measure was frequency of monthly alcohol use, favorable alcohol attitudes, perceived behavioral control (PBC), positive alco...
In the field, plants are challenged by more than one biotic stressor at the same time. In this study, the molecular interactions between potato (Solanum tuberosum L.), Colorado potato beetle (Leptinotarsa decemlineata Say; CPB) and Potato virus Y(NTN) (PVY(NTN) ) were investigated through analyses of gene expression in the potato leaves and the gut of the CPB larvae, and of the release of potat...
Buprenorphine, a maintenance drug for heroin addicts, exerts its pharmacological function via κ- (KOP), μ-opioid (MOP) and nociceptin/opioid receptor-like 1 (NOP) receptors. Previously, we investigated its effects in an in vitro model expressing human MOP and NOP receptors individually or simultaneously (MOP, NOP, and MOP+NOP) in human embryonic kidney 293 cells. Here, we expanded this cell mod...
Sweetpotato (Ipomoea batatas (L.) Lam.) is the third most important root crop in the world, ranking seventh among all crops in global production and fourth in developing countries after rice, wheat, and corn (10). In Africa, sweetpotato plays a vital role in peoples’ ability to sustain their families, especially during periods of hardship. However, sweetpotato plants, like other crops, are sign...
