The nucleotide sequences of cDNA clones of three chrysanthemum stunt viroid (CSVd) isolates (one each from the USA, China, and Australia) were determined and analyzed. The sequences of CSVd cDNA clones of the US and Australian isolates were both quasi-species, while the cDNA clones of the Chinese isolate contained only a single variant. A comparison of the(More)
Transgenic potato plants of Solanum tuberosum cultivar Vales Sovereign were generated that expressed fused, tandem, 200 bp segments derived from the capsid protein coding sequences of potato virus Y (PVY strain O) and potato leafroll virus (PLRV), as well as the cylindrical inclusion body coding sequences of potato virus A (PVA), as inverted repeat(More)
Viroids are naked nucleic acids that do not code for any proteins and yet are able to be replicated, processed, moved cell-to-cell and systemically through their host plants, as well as resist plant defense response and be transmitted from plant to plant, without a protective coat. All of the information specifying these functions lies within their(More)
Four GM plant species (Arabidopsis thaliana, Brassica napus, Nicotiana benthamiana and N. tabacum), each expressing the gene encoding the jellyfish green fluorescent protein (GFP) regulated by the cauliflower mosaic virus (CaMV) 35S RNA promoter, were assessed for the extent of transgene silencing and viral genome integration following infection by CaMV.(More)
The incidence and distribution of Tobacco mosaic virus (TMV) and related tobamoviruses was determined using an enzyme-linked immunosorbent assay on 1,926 symptomatic horticultural crops and 107 asymptomatic weed samples collected from 78 highly infected fields in the major horticultural crop-producing areas in 17 provinces throughout Iran. The results were(More)

A new cucumber mosaic virus (CMV) subgroup based on recent sequence data has been proposed by Palukaitis and Zaitlin (1997) to distinguish between some strains in the former subgroup I. The three subgroups are tentatively named IA, IB and II. Here we describe a simple and rapid procedure based on the reverse transcriptase-polymerase chain reaction (RT-PCR)(More)
