Serological Relationship between Potato Paracrinkle Virus, Potato Virus S and Carnation Latent Virus
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 ...
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...
The common assumption in potato virus epidemiology is that all daughter tubers produced by plants coming from infected mother tubers (secondary infection) will become infected via systemic translocation of the virus during growth. We hypothesize that depending on the prevalent environmental conditions, only a portion of the daughter tubers of a plant that is secondarily infected by viruses may ...
Potato (Solanum tuberosum L.) has relatively weak root system and requires high nitrogen fertilizer which is costly and may pose environmental pollution. This study was conducted to compare root morphological characteristics and nitrogen uptake of some potato cultivars growing in Iran. A greenhouse experiment using a completely randomized design with 3 replications and 8 potato cultivars includ...
