      Twenty‐four isolates of Chilli veinal mottle virus (ChiVMV) from China, India, Indonesia, Taiwan and Thailand were analysed to determine their genetic relatedness. Pathogenicity of virus isolates was confirmed by induction of systemic mosaic and/or necrotic ringspot symptoms on Capsicum annuum after mechanical inoculation. The 3′ terminal sequences of the viral genomic RNA were . Mosaic virus overwinters on perennial weeds and is spread by insects that feed on them. Aphids, leafhoppers, whiteflies and cucumber beetles are common garden pests that can transmit this disease. Soil, seed, starter pots and containers can be infected and pass the virus to the plant.

    Although many of these viruses can also be mechanically transmitted in the laboratory using infected sap, maintenance by mechanical transmission can often lead to changes in the virus, either minor changes in gene sequences or, in some cases, major deletions of genome sequences. These can affect both virus‐vector and virus‐host interactions.   Open Access; Published: 04 June Infection of host plants by Cucumber mosaic virus increases the susceptibility of Myzus persicae aphids .

    An excellent summary of bean aphid ecology was given by Cammell (). Tsitsipis and Mittler () provided information on rearing aphids on both plants and artificial media. Keys for identification of bean aphid, and most other common aphids, are found in Palmer () and Blackman and Eastop (). Cucumber mosaic virus (CMV) is a major component of the virus complex that has become more pronounced in snap bean in the midwestern and northeastern United States since Multiple-vector-transfer tests were done to estimate the CMV transmission efficiencies (p) of the main aphid species identified in commercial snap bean fields in New York.

Comparative aphid and mechanical transmissibility of bean yellow mosaic virus isolates by Ieuan Rhys Evans Download PDF EPUB FB2

Aphid and mechanical transmission properties of bean yellow mosaic virus isolates. Three isolates of bean yellow mosaic virus (BYMV), one from Florida (FV), one from Kentucky (KV) and one from Wisconsin (WV), were compared. Although both the FV and KV isolates proved aphid transmissible, no transmission was obtained in parallel trials with WV.

For each isolate, the sequence of the coat protein and parts of the helper component was determined. A single nucleotide substitution caused a NAG to NAS alteration in the coat protein of the non aphid-transmissible isolate.

Four strains (NL-1, NL-1n, NL-7 and NL-7n) of Bean common mosaic virus (BCMV) prevalent on common bean (Phaseolus vulgaris) in Himachal Pradesh, a north-western Himalayan state of India were compared at the 3′ terminal region of the viral genome to elucidate variation and relationship among these strains.

Mechanical transmission assays resulted in chlorotic local lesions on C. quinoa and C. amaranticolor, mosaic on Vigna unguiculata and Nicotiana benthamiana, and symptoms on sesame that are similar to those observed in the field.

The disease could also be reproduced in sesame by aphid (Myzus persicae) transmission in a nonpersistent manner. TEM. yellow mosaic virus (BYMV) and bean common mosaic virus.

While beans can become infected by multiple viruses, BYMV seems to be the one most frequently observed. Symptoms Although symptoms of BYMV may vary depending on time of infection, bean variety, and virus strain, symptoms generally include one or more of the following: crinkling, downward.

Bean yellow mosaic virus is a plant pathogenic virus in the genus Potyvirus and the virus family other members of the Potyvirus genus, it is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein.

The symptoms of bean yellow mosaic (BYMV) vary again, depending upon the virus strain, stage of growth at the time of infection and variety of bean.

As in BCMV, BYMV will have contrasting yellow or green mosaic markings on the foliage of the infected plant. Factors affecting aphid transmission of bean yellow mosaic virus. Donato Gallitelli, Giovanni P.

mung bean yellow mosaic. To avoid the present confusion in virus names of the Group 2, the authors proposed to use a name of cowpea aphid-borne mosaic virus (CAMV) (Lovisolo and Conti, ) for all members of the Group 2.

The remaining two viruses isolated from cowpea plants were cucumber mosaic virus (CMV) and subclover mottle virus. Bean common mosaic virus and Bean common mosaic necrosis virus are differentiated from Bean yellow mosaic virus and Clover yellow vein virus based on symptoms, host range, seed transmissibility, antibody tests (e.g., ELISA) or PCR-DNA detection methods.

However, because the symptoms of these viruses can overlap in certain bean varieties and. 1 Bean common mosaic virus and Bean common mosaic necrosis virus (genus Potyvirus, family Potyviridae) These two viruses cause what is known as the common mosaic disease of bean.
