Molecular characterization of closteroviruses infecting Cordyline fruticosa L. in Hawaii

Frontiers in Microbiology, 2013
In Hawaii, common green ti plants (Cordyline fruticosa L.) have been shown to harbor Cordyline virus 1 (CoV-1) which, along with Little cherry virus 1 (LChV-1) and Grapevine leafroll-associated virus 7 (GLRaV-7), form a distinct clade within the family ...

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

Journal 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.

Completion of the mapping of transcription start sites for the five-gene block subgenomic RNAs of Beet yellows Closterovirus and identification of putative subgenomic promoters

, 2007
In the positive-senseRNAgenome of Beet yellows Closterovirus (BYV), the 3-terminal open reading frames (ORFs) 2–8 are expressed as a nested set of subgenomic (sg) RNAs.

Prospects of classical cross protection technique against Citrus tristeza closterovirus in Pakistan: A review

Horticultural Science, 2005
In Pakistan citrus groves in general are facing a serious problem of decline that is attributed to different causes. The major cause, however, is the prevalence of citrus virus and virus-like diseases; Citrus tristeza virus (CTV) is of utmost concern ...

Phytohormones and emerging plant growth regulators in tailoring plant immunity against viral infections

Physiologia Plantarum, Volume 177, Issue 2, March/April 2025.
Abstract Viral infections are major contributors to crop yield loss and represent a significant threat to sustainable agriculture. Plants respond to virus attacks by activating sophisticated signalling cascades that initiate multiple defence mechanisms.

The defective RNAs of Closteroviridae

Frontiers in Microbiology, 2013
The family Closteroviridae consists of two genera, Closterovirus and Ampelovirus with monopartite genomes transmitted respectively by aphids and mealybugs and the Crinivirus with bipartite genomes transmitted by whiteflies.

Aerial low‐altitude remote sensing and deep learning for in‐field disease incidence scoring of virus yellows in sugar beet

Plant Pathology, Volume 73, Issue 9, Page 2310-2324, December 2024.
UAVs and CNNs show promise in automating disease scoring in sugar beets, offering efficiency and objectivity, but human expertise remains crucial for validation, especially for subtle disease symptoms. Abstract This study investigates the potential of high‐resolution (<0.5 cm/pixel) aerial imagery and convolutional neural networks (CNNs) for disease ...

Legume viruses in Finland [PDF]

, 2021
Palkokasvien viljely on kasvavan kiinnostuksen kohteena Suomessa, mutta palkokasvien viruksia on maassamme kartoitettu ja tutkittu verrattain vähän. Muuttuva ilmasto luo uudenlaisia uhkia myös palkokasvituotannolle.

Time point of virus yellows infection is crucial for yield losses in sugar beet, and co‐infection with beet mosaic virus is negligible under field conditions

Plant Pathology, Volume 73, Issue 8, Page 2056-2070, October 2024.
Early virus yellows infections cause significant yield loss in sugar beet while late infections do not. Beet mosaic virus alone does not cause significant yield losses; only in co‐infection with beet mild yellowing virus (BMYV), losses exceed those from single BMYV infection.

bZIP60 and Bax inhibitor 1 contribute IRE1‐dependent and independent roles to potexvirus infection

New Phytologist, Volume 243, Issue 3, Page 1172-1189, August 2024.
Summary IRE1, BI‐1, and bZIP60 monitor compatible plant–potexvirus interactions though recognition of the viral TGB3 protein. This study was undertaken to elucidate the roles of three IRE1 isoforms, the bZIP60U and bZIP60S, and BI‐1 roles in genetic reprogramming of cells during potexvirus infection.
