Direct and Indirect Effect via Endophytism of Entomopathogenic Fungi on the Fitness of Myzus persicae and Its Ability to Spread PLRV on Tobacco

Insects, 2021
Aphids are major crop pests that transmit more than half of all insect-vectored plant viruses responsible for high yield losses worldwide. Entomopathogenic fungi (EPF) are biological control agents mainly used by foliar application to control herbivores,

The Effects of High Temperature on Infection by Potato virus Y, Potato virus A, and Potato leafroll virus

The Plant Pathology Journal, 2016
We examined the effects of temperature on acquisition of Potato virus Y-O (PVY-O), Potato virus A (PVA), and Potato leafroll virus (PLRV) by Myzus persicae by performing transmission tests with aphids that acquired each virus at different temperatures ...

Potato leafroll virus: A re‐emerging threat to sustainable potato production

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Potato leafroll virus (PLRV) is a positive‐strand RNA virus. Virus particles of PLRV are isometric, 24 nm in diameter. PLRV is the causal agent of leafroll disease in potato (Solanum tuberosum L.) which causes significant losses in yield and quality of potato tubers.

Expression patterns of vascular-specific promoters RolC and Sh in transgenic potatoes and their use in engineering PLRV-resistant plants

, 1997
The expression patterns of GUS fusion constructs driven by the Agrobacterium rhizogenes RolC and the maize Sh (Shrunken: sucrose synthase-1) promoters were examined in transgenic potatoes (cv. Atlantic).

Effects of Elevated CO2 on Bean Pod Mottle Virus Infection in Both Incompatible and Compatible Interactions With Phaseolus vulgaris L

Plant, Cell &Environment, Volume 49, Issue 7, Page 4493-4512, July 2026.
ABSTRACT Plant viruses cause significant crop losses, a situation that could worsen due to anthropogenic activities driving global climate change, one factor of which is the increase in atmospheric CO2 concentration. This study assessed the impact of elevated CO2 concentration (eCO2, 1000 vs. 400 ppm) on two genotypes of common bean (Phaseolus vulgaris

The Three Essential Motifs in P0 for Suppression of RNA Silencing Activity of Potato leafroll virus Are Required for Virus Systemic Infection

Viruses, 2019
Higher plants exploit posttranscriptional gene silencing as a defense mechanism against virus infection by the RNA degradation system. Plant RNA viruses suppress posttranscriptional gene silencing using their encoded proteins.

Effect of PLRV infected seed tuber on disease incidence, plant growth and yield parameters of potato

, 1970
An investigation was conducted to find out the effect of PLRV infected seed tubers on disease incidence, plant growth, and tuber yield of potato. The levels of PLRV infected seed tubers were 0, 10, 20, 33, and 100%. Presence of PLRV infected tubers at 20%
