Accumulation of 24 nucleotide transgene‐derived siRNAs is associated with crinivirus immunity in transgenic plants [PDF]

Molecular Plant Pathology, 2018
Summary RNA silencing is a conserved antiviral defence mechanism that has been used to develop robust resistance against plant virus infections. Previous efforts have been made to develop RNA silencing‐mediated resistance to criniviruses, yet none have given immunity.

The p22 RNA Silencing Suppressor of the Crinivirus Tomato chlorosis virus is Dispensable for Local Viral Replication but Important for Counteracting an Antiviral RDR6-Mediated Response during Systemic Infection

Viruses, 2016
Among the components of the RNA silencing pathway in plants, RNA-dependent RNA polymerases (RDRs) play fundamental roles in antiviral defence. Here, we demonstrate that the Nicotiana benthamiana RDR6 is involved in defence against the bipartite ...

First Report of Crinivirus Tomatichlorosis Infecting Tomato Plants in Argentina

Journal of Phytopathology
ABSTRACT Tomato is mainly produced in five main areas distributed in western, northern, eastern and south Argentina. In Jujuy, Argentina, tomato plants with yellowing, rolling, brittleness leaves symptoms were observed and samples were taken to the lab.

Defective RNAs of Citrus tristeza virus analogous to Crinivirus genomic RNAs [PDF]

Virology, 2003
The family Closteroviridae includes the genera Closterovirus and Ampelovirus with monopartite genomes and the genus Crinivirus with bipartite genomes. Plants infected with the Closterovirus, Citrus tristeza virus (CTV), often contain one or more populations of defective RNAs (dRNAs).

Synergistic Interactions of a Potyvirus and a Phloem-Limited Crinivirus in Sweet Potato Plants [PDF]

Virology, 2000
When infecting alone, Sweet potato feathery mottle virus (SPFMV, genus Potyvirus) and Sweet potato chlorotic stunt virus (SPCSV, genus Crinivirus) cause no or only mild symptoms (slight stunting and purpling), respectively, in the sweet potato (Ipomoea batatas L. ). In the SPFMV-resistant cv.

Nucleotide sequence and genome organization of a new proposed crinivirus, tetterwort vein chlorosis virus

Archives of Virology, 2015
The genome of tetterwort vein chlorosis virus (TVCV) from South Korea has been completely sequenced. Its genomic organization resembles those of other criniviruses, with several new features, indicating that TVCV is a member of a new species in the genus Crinivirus, family Closteroviridae.

The Heterologous Expression of the p22 RNA Silencing Suppressor of the Crinivirus Tomato Chlorosis Virus from Tobacco Rattle Virus and Potato Virus X Enhances Disease Severity but Does Not Complement Suppressor-Defective Mutant Viruses

Viruses, 2017
To counteract host antiviral RNA silencing, plant viruses express suppressor proteins that function as pathogenicity enhancers. The genome of the Tomato chlorosis virus (ToCV) (genus Crinivirus, family Closteroviridae) encodes an RNA silencing suppressor,

Agave associated crinivirus A: a novel monopartite crinivirus homolog isolated from agave. [PDF]

Arch Virol
Abstract We describe the complete genome of the first monopartite and putative member of the genus Crinivirus which we propose naming agave associated crinivirus A (AaCA). AaCA was identified by high-throughput sequencing in an Agave tequilana

Phylogenetic Analysis of Cucurbit Chlorotic Yellows Virus from Melon in 2020 in Chungbuk, Korea [PDF]

Research in Plant Disease, 2023
Cucurbit chlorotic yellows virus (CCYV) is a plant virus that causes damage to cucurbit crops such as watermelon and cucumber, and is transmitted by an insect vector known as the whitefly. Since CCYV was first detected on cucumber in Chungbuk in 2018, it
