To better understand the naturally occurring host range of Bean pod mottle virus (family Comoviridae, genus Comovirus, BPMV) and its principal vector Cerotoma trifurcata (Förster) (Coleoptera: Chrysomelidae), 18 field-collected perennial plant species were tested for the presence of BPMV. By using no-choice assays, we determined the preference of these plants by bean leaf beetle, by measuring t...

Microtubules are closely associated with tubules containing virus particles in leaf cells infected with bean pod mottle virus or cowpea mosaic virus. The similar orientation and apparent continuity suggest that cores of tubules with virus particles are actually microtubules. It is suggested that microtubules may be involved in the intraand intercellular movement of viral components and in the a...

Beet curly top virus, often referred to as Curly top virus (CTV), is an important virus disease of common bean in the semiarid regions of the United States, Canada, and Mexico and the only effective control is genetic resistance. Our objective was to determine if dry bean landrace G122, which lacks the Bct gene for resistance to CTV, contains novel resistance to the virus. Two populations, GT-A...

(2015) Establishment of a minigenome system for oropouche virus reveals the S genome segment to be significantly longer than reported previously, Abstract 33 34 Oropouche virus (OROV) is a medically important orthobunyavirus, which causes 35 frequent outbreaks of a febrile illness in the Northern parts of Brazil. However, despite 36 being the cause for an estimated half a million human infectio...

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...

The genome components of the Melon chlorotic leaf curl virus (MCLCuV) were cloned from symptomatic cantaloupe leaves collected in Guatemala during 2002. The MCLCuV DNA-A and DNA-B components shared their closest nucleotide identities among begomoviruses, at approximately 90 and 81%, respectively, with a papaya isolate of MCLCuV from Costa Rica. The closest relatives at the species level were ot...
