Identification of cucurbit chlorotic yellows virus P4.9 as a possible movement protein

open access: yesVirology Journal, 2019
Background Cucurbit chlorotic yellows virus (CCYV) is a bipartite cucurbit-infecting crinivirus within the family Closteroviridae. The crinivirus genome varies among genera. P4.9 is the first protein encoded by CCYV RNA2. P5, which is encoded by LIYV, is

GATA8‐Mediated Antiviral Defence Is Countered by Tomato Chlorosis Virus‐Encoded Pathogenicity Protein p27

open access: yesMolecular Plant Pathology, Volume 26, Issue 7, July 2025.
GATA8 enhances the antiviral defence of tomato plants against tomato chlorosis virus by binding to the promoter of SnRK2, thereby regulating its expression. However, this process is counteracted by the viral p27 protein. ABSTRACT Tomato chlorosis virus (ToCV), a phloem‐restricted RNA virus within the genus Crinivirus of the family Closteroviridae ...

Neophytadiene, a Plant Specialized Metabolite, Mediates the Virus‐Vector‐Plant Tripartite Interactions

open access: yesAdvanced Science, Volume 12, Issue 22, June 12, 2025.
Tomato chlorosis virus (ToCV) infection induces production of neophytadiene, a volatile resulting from chlorophyll degradation that is highly attractive to whiteflies. OBP2, an odorant‐binding protein from insect vector B. tabaci, exhibits a strong binding affinity for neophytadiene.

Systemic and Phloem‐Specific Protein Targeting by High Affinity Nanobodies Expressed From a Plant RNA Virus Vector

open access: yesMolecular Plant Pathology, Volume 26, Issue 6, June 2025.
This proof‐of‐concept study, with validation by pull‐down assays and FRET‐FLIM measurements, establishes a platform for targeting proteins in the phloem by nanobodies expressed from a viral vector. ABSTRACT The emergence of nanobodies (Nbs) has kindled an avid interest for their use in genetic engineering and plant biotechnology.

Vector Biology of the Soft Scales Parthenolecanium corni (Bouché) and Parthenolecanium persicae (Fabricius) (Hemiptera: Coccidae) With Grapevine Leafroll‐Associated Viruses and Grapevine Virus A

open access: yesJournal of Applied Entomology, Volume 149, Issue 3, Page 405-416, April 2025.
ABSTRACT Controlled experiments were conducted to enrich our knowledge on the transmission of different grapevine leafroll‐associated ampeloviruses (GLRaV‐1, ‐2, ‐3 and ‐4) by Parthenolecanium corni scale insect and to look for vector ability of Parthenolecanium persicae. GLRaV‐1 and the vitivirus GVA were transmitted by P.

Lettuce Chlorosis Virus Disease: A New Threat to Cannabis Production

open access: yesViruses, 2019
In a survey conducted in Cannabis sativa L. (cannabis) authorized farms in Israel, plants showed disease symptoms characteristic of nutrition deprivation. Interveinal chlorosis, brittleness, and occasional necrosis were observed in older leaves.

Characterization of virus species associated with sweet potato virus disease in Costa Rica and riboprobe development for its rapid detection

open access: yesPlant Pathology, Volume 74, Issue 2, Page 413-421, February 2025.
Sweet potato feathery mottle virus and sweet potato chlorotic stunt virus have high prevalence in Costa Rica. Riboprobes are a cost‐effective alternative to RT‐PCR for virus detection in large‐scale screenings. Abstract Sweet potato (Ipomoea batatas) is a crucial crop for food security and economic stability in many regions, including Costa Rica.
