The Ophioviridae is a family of filamentous plant viruses, with single-stranded negative, and possibly ambisense, RNA genomes 11.3-12.5 kb divided into 3-4 segments, each encapsidated separately. Virions are naked nucleocapsids, forming kinked circles at least two different contour lengths. sole genus, Ophiovirus, includes seven species. Four ophioviruses soil-transmitted their natural hosts include trees, shrubs, vegetables bulbous or corm-forming ornamentals, both monocots dicots. This...
Summary Sweet orange ( C itrus sinensis ), one of the most important fruit crops worldwide, may suffer from disease symptoms induced by virus infections, thus resulting in dramatic economic losses. Here, we show that infection sweet plants with two isolates psorosis CPsV ) expressing different symptomatology alters accumulation a set endogenous microRNAs miRNAs ). Within these , miR156 miR167 and miR171 were down‐regulated, almost three‐fold reduction infected samples. This down‐regulation...
Abstract Numerous cell surface receptors and receptor-like proteins (RLPs) undergo activation or deactivation via a transmembrane domain (TMD). A subset of plant RLPs distinctively localizes to the plasma membrane-lined pores called plasmodesmata. Those include Arabidopsis thaliana Plasmodesmata-located protein (PDLP) 5, which is well known for its vital function regulating plasmodesmal gating molecular movement between cells. In this study, we report that TMD, although not determining...
Abstract Effective cellular signaling relies on precise spatial localization and dynamic interactions among proteins in specific subcellular compartments or niches, such as cell-to-cell contact sites junctions. In plants, endogenous pathogenic gained the ability to target plasmodesmata, membrane-lined cytoplasmic connections, through evolution regulate exploit across cell wall boundaries. For example, receptor-like membrane protein PLASMODESMATA-LOCATED PROTEIN 5 (PDLP5), a potent regulator...
Infection by citrus psorosis virus (CPsV) involves a self-cleaving aspartic protease activity within the viral movement protein (MP), which results in production of two peptides, termed 34K CPsV and 20K , that carry MP activities, respectively. The underlying motif is also found MPs other members Aspiviridae family, suggesting protease-mediated processing represents conserved mechanism expression this family. demonstrate potentially ophioviruses move tubule-guided mechanism. Although several...
Lettuce big-vein disease (BVD) affects all major lettuce-producing areas of the world. The causal agent is Mirafiori lettuce virus (MLBVV), an ophiovirus transmitted by soil-borne fungus Olpidium brassicae (Lot et al., 2002). MLBVV has been detected in many different world but never Argentina. La Plata about 700 ha with a production 13 000 tonnes, and 70% total from Buenos Aires Province. BVD north west horticultural green belt. Many plants symptoms had leaf distortions moderate severity,...
Summary RNA transport and localization represent important post‐transcriptional mechanisms to determine the subcellular of protein synthesis. Plants have capacity messenger (m)RNA molecules beyond cell boundaries through plasmodesmata over long distances in phloem. viruses exploit these pathways disseminate their infections model systems investigate plants. Here, we present an vivo plant RNA‐labeling system based on Escherichia coli RNA‐binding BglG. Using detection mobile particles formed...

In plants, both endogenous pathogenic gained ability to target plasmodesmata, membrane-lined cytoplasmic connections, regulate exploit cellular across cell wall boundaries. Those include receptor-like membrane protein PDLP5, a potent regulator plasmodesmal permeability that generates feed-forward...
