Interactive effects of Potato virus Y and Potato leafroll virus infection on potato yields in Uganda

Open Agriculture, 2020
Potatoes are prone to attack by multiple viruses, which contribute greatly to yield and quality decline depending on the cultivar and the virus involved.

A Major Quantitative Trait Locus for Resistance to Potato leafroll virus Is Located in a Resistance Hotspot on Potato Chromosome XI and Is Tightly Linked to N-Gene-Like Markers

Molecular Plant-Microbe Interactions, 2001
Potato leafroll virus (PLRV) causes one of the most widespread and important virus diseases in potato. Resistance to PLRV is controlled by genetic factors that limit plant infection by viruliferous aphids or virus multiplication and accumulation ...

Seed potato quality improvement through positive selection by smallholder farmers in Kenya [PDF]

, 2011
In Kenya, seed potato quality is often a major yield constraint in potato production as smallholder farmers use farm-saved seed without proper management of seed-borne pests and diseases. Farm-saved seed is therefore often highly degenerated.

Late blight and virus host-plant resistances, crossing ability and glycoalkaloids in Nordic potato germplasm

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
Old potato cultivars from the Nordic Genetic Resource Center (NordGen) and advanced breeding clones from the Swedish University of Agricultural Sciences (SLU) were evaluated for susceptibility to Potato Virus Y (PVY) and Potato Leafroll Virus (PLRV ...

Need for Local Laboratory Reference Values in Recruitment into Studies of Emerging Infectious Diseases: Insight from Participant Screening for an Ebola Vaccine Trial in a Rural African Setting

Proceedings, 2020
Introduction: The EBOVAC-Salone trial of a candidate Ebola two-dose vaccine regimen (Ad.ZEBOV/MVA-BN-Filo) was conducted in a research-naïve setting in rural northern Sierra Leone, where no local laboratory reference values (LRV) had been established. In

Plant Viruses Transmitted in Two Different Modes Produce Differing Effects on Small RNA-Mediated Processes in Their Aphid Vector

Phytobiomes Journal, 2019
Transmission of plant viruses by aphids involves multitrophic interactions among host plants, aphid vectors, and plant viruses. Here, we used small RNA (sRNA) sequencing to visualize the sRNA response of Myzus persicae to two plant viruses that M ...

Host-Dependent Requirement for the Potato leafroll virus 17-kDa Protein in Virus Movement

Molecular Plant-Microbe Interactions, 2002
The requirement for the 17-kDa protein (P17) of Potato leafroll virus (PLRV) in virus movement was investigated in four plant species: potato (Solanum tuberosum), Physalis floridana, Nicotiana benthamiana, and N. clevelandii.

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,
