cucumber mosaic virus (cmv) is one of the causal agents of viral diseases that infected mint (mentha spp.). cmv is a member of the cucumovirus genus in  bromoviridae family. the virus is naturally transmitted by aphids in a non-persistent manner.during  growing season 2007-2008, leaf samples from plants of mint fields with symptoms of viral disease were collected in mint fieldas in tehran provi...

Monoclonal antibodies were obtained against Tomato mosaic tobamovirus (ToMV) isolated in Brazil. One antibody (8G7G2) isotyped as IgG2b (κ light chain) showed strong specificity and very low cross reaction with the Tobacco mosaic virus (TMV). It can be used in identification of tomato mosaic virus (ToMV).

Protoplasts isolated from tobacco leaves were inoculated with cucumber mosaic virus (CMV) using a method slightly modified from that developed for inoculating tobacco mosaic virus. Multiplication of CMV was demonstrated by staining the protoplasm with fluorescent CMV-antibody, by the electron microscopy of ultrathin sections, and by assaying the infectivity in protoplasts. Seventy to 90% of pro...

Leaves of tobacco plant cv. Xanthi-nc inoculated or systemically infected with potato virus Y, cucumber mosaic virus, potato virus X, potato aucuba mosaic virus or alfalfa mosaic virus showed varying degrees of resistance to infection with tobacco mosaic virus. The resistance was correlated with the appearance of at least three proteins not present in healthy plants. These were the proteins tha...

In order to assess the occurrence, distribution and importance of viral diseases of mungbean and mashbean crops in Punjab, Pakistan, an extensive survey was conducted during summer season of 2004. The symptomatic plant samples were collected from farmer’s fields and experimental plots at research stations and tested by Enzyme-linked Immunosorbent Assay (ELISA) to detect and identify viruses inf...

The major threat for cassava cultivation on the Indian subcontinent is cassava mosaic disease (CMD) caused by cassava mosaic geminiviruses which are bipartite begomoviruses with DNA A and DNA B components. Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosaic virus (SLCMV) cause CMD in India. Two isolates of SLCMV infected the cassava cultivar Sengutchi in the fields near Malappuram ...

Background Jatropha curcas is a drought resistant shrub native in tropical America, now widely grown in many tropical and subtropical regions for biodiesel production [1]. First reports on virus infections in Jatropha indicated the occurrence of viruses closely related to Cassava mosaic virus in India, reaching a disease incidence from 25 to 47%. This might represent a major constrain to the pr...

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...

Occurence and Yield Effects of Wheat Infected with Triticum Mosaic Virus Authors: D.L. Seifers, J.T. Martin, J.P. Fellers Submitted to: Plant Disease Triticum mosaic virus (TriMV) was discovered recently and little is known about the virus’ biology and potential to cause yield reductions. TriMV has been found all across the Great Plains and this study examined whether TriMV infection would re-o...
