Genetic Variation of Turnip Yellows Virus in Arable and Vegetable Brassica Crops, Perennial Wild Brassicas, and Aphid Vectors Collected from the Plants

Ricardo José Gonzaga Pimenta, Kyle Macleod, Robyn Babb, Kaitlyn Coleman et autres

Turnip yellows virus (TuYV; Polerovirus, Solemoviridae) infects and causes yield losses in a range of economically important crop species, particularly the Brassicaceae. It is persistently transmitted by several aphid species and is difficult to control. Although the incidence and genetic diversity of …

A review of sources of resistance to turnip yellows virus ( TuYV ) in Brassica species

Kyle Macleod, Shannon F. Greer, Lawrence E. Bramham, Ricardo José Gonzaga Pimenta et autres

Abstract Turnip yellows virus (TuYV; previously known as beet western yellows virus) causes major diseases of Brassica species worldwide resulting in severe yield‐losses in arable and vegetable crops. It has also been shown to reduce the quality of vegetables, particularly cabbage where …

Identification and genetic inheritance of a new source of broad-spectrum extreme resistance to turnip mosaic virus (TuMV) in Brassica rapa

Hanna M. Walsh, Antti Rönkä, John A. Walsh

Abstract Brassica rapa line K185 was identified with broad-spectrum extreme resistance to turnip mosaic virus (TuMV). The resistance was effective against TuMV isolates UK 1, CZE 1, GBR 6, POL 1 and CDN 1 (representing major pathotypes 1, 3 and 4 and …

Characterization and Mapping of retr04, retr05 and retr06 Broad-Spectrum Resistances to Turnip Mosaic Virus in Brassica juncea, and the Development of Robust Methods for Utilizing Recalcitrant Genotyping Data

Lawrence E. Bramham, Tongtong Wang, Erin E. Higgins, Isobel A. P. Parkin et autres

Turnip mosaic virus (TuMV) induces disease in susceptible hosts, notably impacting cultivation of important crop species of the Brassica genus. Few effective plant viral disease management strategies exist with the majority of current approaches aiming to mitigate the virus indirectly through control …

Quantitative Trait Locus Mapping of Resistance to Turnip Yellows Virus in Brassica rapa and Brassica oleracea and Introgression of These Resistances by Resynthesis Into Allotetraploid Plants for Deployment in Brassica napus

Shannon F. Greer, Dieter Hackenberg, Vasilis C. Gegas, Georgia Mitrousia et autres

Turnip yellows virus (TuYV) is aphid-transmitted and causes considerable yield losses in oilseed rape (OSR, Brassica napus, genome: AACC) and vegetable brassicas. Insecticide control of the aphid vector is limited due to insecticide resistance and the banning of the most effective active …

Sequence analysis of 43‐year old samples of Plantago lanceolata show that Plantain virus X is synonymous with Actinidia virus X and is widely distributed

John Hammond, Ian P. Adams, A. Fowkes, Sam McGreig et autres

Abstract Plantain virus X was first recognized by the ICTV as a species in the genus Potexvirus in 1982. However, because no sequence was available for plantain virus X (PlVX), abolishing the species was proposed to the Flexiviridae working group of the …
