Amino Acids in the Capsid Protein of Tomato Yellow Leaf Curl Virus That Are Crucial for Systemic Infection, Particle Formation, and Insect Transmission
ABSTRACT A functional capsid protein (CP) is essential for host plant infection and insect transmission in monopartite geminiviruses. We studied two defective genomic DNAs of tomato yellow leaf curlExpand
Molecular characterization of the plant virus genus Ourmiavirus and evidence of inter-kingdom reassortment of viral genome segments as its possible route of origin.
Ourmia melon virus (OuMV), Epirus cherry virus (EpCV) and Cassava virus C (CsVC) are three species placed in the genus Ourmiavirus. We cloned and sequenced their RNA genomes. The sizes of the threeExpand
An Ophiovirus isolated from lettuce with big-vein symptoms
Summary. Big-vein is a widespread and damaging disease of lettuce, transmitted through soil by the chytrid fungus Olpidium brassicae, and generally supposed to be caused by Lettuce big-vein virusExpand
Partial characterization of a new virus from ranunculus with a divided RNA genome and circular supercoiled thread-like particles
SummaryAn undescribed virus, here named ranunculus white mottle virus, was isolated in Italy from cultivated ranunculus showing mottle and distortion of leaves. The virus was mechanicallyExpand
Field Isolates of Tomato spotted wilt virus Overcoming Resistance in Pepper and Their Spread to Other Hosts in Italy.
Isolates of Tomato spotted wilt virus (TSWV) severely and systemically infecting commercial pepper cultivars with resistance introgressed from Capsicum chinense PI152225 were found in AlbengaExpand
A Severe Disease of Tomato in the Culiacan Area (Sinaloa, Mexico) Is Caused by a New Picorna-Like Viral Species.
We were able to mechanically transmit a small isometric virus from field tomato samples showing severe necrotic symptoms, collected in the Culiacan area of Sinaloa state (Mexico). After gradientExpand
Functional expression in bacteria and plants of an scFv antibody fragment against tospoviruses.
We engineered an antibody fragment from a monoclonal antibody able to recognise an epitope of the glycoprotein G1 conserved among a large number of tospoviruses. Expand
A member of a new Tospovirus species isolated in Italy from wild buckwheat (Polygonum convolvulus)
Electron microscopy of extracts from diseased Polygonum convolvulus plants from Piedmont (Italy) revealed particles with the morphological features of a tospovirus. Sequencing of the full-lengthExpand
Characterization of two Tospoviruses in Italy: tomato spotted wilt and impatiens necrotic spot
Tospovirus serogroups I and III have recently been designated as species, tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV), while the species status of serogroup II isolatesExpand
