ABSTRACT Data collected in 2002 and 2003 on Alfalfa mosaic virus and Cucumber mosaic virus incidences of infection in commercial snap bean fields in New York State were used to develop relationships between disease incidence (p(low)) and sample size while accounting for the inherent spatial aggregation of infected plants observed with these two viruses. For a plan consisting of 300 sampled plan...

A generic assay to detect and partially characterize unknown viruses from plants was developed. Proteins extracted from virus-infected and uninfected plants were separated in one dimension by SDS polyacrylamide gel electrophoresis. Differentially expressed protein bands were eluted after trypsin digestion and resulting peptide fragments separated according to their mass by matrix-assisted laser...

The plant viruses alfalfa mosaic virus (AMV) and brome mosaic virus (BMV) each divide their genetic information among three RNAs while tobacco mosaic virus (TMV) contains a single genomic RNA. Amino acid sequence comparisons suggest that the single proteins encoded by AMV RNA 1 and BMV RNA 1 and by AMV RNA 2 and BMV RNA 2 are related to the NH2-terminal two-thirds and the COOH-terminal one-thir...

The 3' termini of Alfalfa mosaic virus (AMV) RNAs adopt two mutually exclusive conformations, a coat protein binding (CPB) and a tRNA-like (TL) conformer, which consist of a linear array of stem-loop structures and a pseudoknot structure, respectively. Previously, switching between CPB and TL conformers has been proposed as a mechanism to regulate the competing processes of translation and repl...

A full-length cDNA clone of alfalfa mosaic virus (AMV) RNA3 was prepared and sequenced. The 2,037 base sequence contains two open reading frames of 903 and 666 nucleotides that code for a 32,400 dalton protein (32.4K protein) and the 24,380 dalton coat protein, respectively. A 5'-noncoding sequence of 240 bases preceeding the 32.4K protein contains homologous regions that may have a function in...

This is the first report of chrysanthemum virus B (CVB) and chlorotic mottle viroid (CChMVd) on Chrysanthemum × morifolium cultivars, in South Africa. Samples were collected from plants showing vein clearing, mosaic chlorosis, Western Cape province. RNAtag-seq was applied indicated presence CVB all four samples co-infection with CChMVd one sample. The confirmed using RT-PCR Sanger sequencing.

In this study, it was aimed to reveal some viruses that are a problem in tomato production areas the Ereğli district of Konya, where is common. For reason, 2019 season, leaf samples were taken from 160 plants showing symptoms similar virus disease such as mosaic, deformations, yellowing, blight on leaves and stunted plants. Possible infections Cucumber mosaic (CMV), Tomato spotted-wilt (TSWV) (...
