Viral diseases are major constraints to tomato, cucumber and mung bean production in most areas where these crops grown. To identify the viruses on Tajikistan, a field survey was conducted 2019. Samples of cucumber, tomato with virus-like symptoms were collected present diagnosed by RT-PCR PCR. Across all samples, very high proportion samples infected from genera Cucumovirus Potyvirus. Cucumber...

Viral attacks on natural populations of herbaceous forage legumes might have adverse effect on seed and herbage production, hence this study was carried out to investigate the type and incidence of viruses occurring on these plants in Nigeria. Protein A-sandwich (PAS) and antigen-coated plate (ACP) enzyme-linked immunosorbent assays (ELISA) were used to detect ten legume viruses from 100 leaf s...

The present study was carried out to detect the presence of Alfalfa mosaic alfamovirus (AMV), cucumber mosaic cucumovirus (CMV), lettuce mosaic potyvirus (LMV), cucumber green mottle mosaic virus (CGMMV), tomato bushy stunt tombusvirus (TBSV), tobacco mosaic tobamovirus (TMV), tomato black ring nepovirus (TBRV) and tomato mosaic tobamovirus (ToMV) in seeds of pepper, tomato, cucumber and lettuc...

virus infections are a major limiting factor in cucurbit production in iran. cucumber green mottle mosaic virus (cgmmv) infects many cucurbit species in the world and causing mottle and systemic mosaic symptoms on cucurbitaceous plant leaves. during 2008-2009, from different cucurbitaceous species fields and cucumber greenhouses in razavi and northern khorasan provinces, 220 leaf samples with c...

Transgenic tobacco showing replicase-mediated resistance against cucumber mosaic virus (CMV) can be infected by the strain K-CMV. By use of chimeric constructs between full-length cDNA clones of RNA2 of strains Fny-CMV and K-CMV, the existence of two independent mechanisms of replicase-mediated resistance against viral replication and movement of Fny-CMV was demonstrated in these plants. The da...

We compared some fitness components of the wild squash species Cucurbita pepo spp. ovifera var. texana (C. texana) and three generations of hybrids (F1, BC1, and BC2) between C. texana and commercial transgenic squash CZW-3 over three consecutive years under field conditions of low (LDP) and high disease pressure (HDP) by Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV) and Wate...

Transmission experiments of different isolates of Cucumber mosaic virus (CMV), Watermelon mosaic virus (WMV) and Zucchini yellow mosaic virus (ZYMV) were conducted using established colonies of Aphis gossypii Glover, Myzus persicae (Sulzer), A. fabae Scopoli and A. craccivora Koch as vectors. The transmission procedure used provided an estimate of the virus transmission efficiency for each aphi...
