Zucchini yellow mosaic virus (ZYMV) causes serious damage to cucurbit crops worldwide and can be spread by aphids, mechanical injury, in seeds. With the popularization of grafting, use susceptible rootstock has increased risk ZYMV infection crops. In China, bottle gourd ( Lagenaria siceraria ) is a widely used grafted watermelon production. However, few resistant gourds are available commercial...
Tobacco mosaic virus (TMV) RN.4 and TMV coat protein were reconstitut,ed in the presence of an excess of host RNA or turnip yellow mosaic virus (TYMV) RNA. TMV protein and its homologous RNA recognized each other specifically in the presence of an excess of host RNA, but when TMV RNA and TYMV RNA were mixed with protein, both RNAs were encapsidated. Indeed, at pH 6, TYMV RNA was recognized by T...
The past fifty years important advances have been made in the field of grapevine virus research, including characterization of pathogens and control measurements. Still the occurrence of Grapevine fanleaf virus (GFLV), Arabis mosaic virus (ArMV), Tomato black ring virus (TBRV), Grapevine chrome mosaic virus (GCMV), Alfalfa mosaic virus (AMV), Grapevine Bulgarian latent virus (GBLV), Grapevine f...
Watermelon chlorotic stunt virus (WmCSV) is a bipartite begomovirus (genus Begomovirus, family Geminiviridae) that causes economic losses to cucurbits, particularly watermelon, across the Middle East and North Africa. Recently squash (Cucurbita moschata) grown in an experimental field in Oman was found to display symptoms such as leaf curling, yellowing and stunting, typical of a begomovirus in...
ویروس موزائیک هندوانه(watermelon mosaic virus, wmv) یکی از پوتیویروسهای مهم و گسترده در دنیا است که به کدوئیان خسارت وارد می کند. wmv دامنه میزبانی نسبتا وسیعی دارد و تمایز آن بر اساس دامنه میزبانی از سایر ویروس های کدوئیان مشکل است. به منظور ردیابی وتعیین پراکنش این ویروس در مزارع استان گلستان 179 نمونه از گیاهان کدو، هندوانه، خربزه و خیار از شش منطقه استان گلستان جمع آوری و با آنتی سرم wmv ...
turnip mosaic virus (tumv), cauliflower mosaic virus (camv) and beet western yellow virus (bwyv) are considered as the most important viruses of canola, worldwide. in order to determine the distribution of these viruses in golestan province, samples from three important canola growing areas of the province were collected during 2008 and 2009. the randomly collected samples were tested for the p...
Geminiviruses are a group of plant viruses that contain circular single stranded (ss) DNA genomes encapsidated in small twinned icosahedral capsids .The virus DNA A plus strand encodes the coat protein (CP/AV1) essential for viral transmission by whiteflies (Bemisia tabaci)[4]. Jatropha has been found to have strong molluscicidal activity and the latex to be strongly inhibitory to watermelon mo...
Artificial microRNAs (amiRNAs) are the expression products of engineered microRNA (miRNA) genes that efficiently and specifically downregulate RNAs that contain complementary sequences. Transgenic plants expressing high levels of one or more amiRNAs targeting particular sequences in the genomes of some RNA viruses have shown specific resistance to the corresponding virus. This is the case of th...
two hundred and thirty one leaf samples of virus infected and mosaic and as well dwarf mosaic symptoms showing maize plants from various corn fields in tehran province were collected during the growing season 2003. by performing serological tests of das-elisa, diba and tpia, using scmv, mdmv, srmv and jgmv antisera, only scmv was detected in samples, with all samples reacting strongly to the sc...
Background and Aims: Celery mosaic virus (CeMV) is one of the causal agents of viral diseases in celery (Apium graveolens). CeMV is a member of the Potyvirus genus in Potyviridae family. The virus is naturally transmitted by aphids in a non-persistent manner. During growing season 2006-2007 viral disease symptoms were observed in celery fields grown in Tehran Province (Bage daneshkade, Mohamads...
