Detection and Partial Characterization of Polerovirus and Luteovirus Isolates Associated With Lentil and Chickpea in Ethiopia

Legume Science
The partial nucleotide sequence of the coat protein (CP) gene of Ethiopian isolates of chickpea chlorotic stunt virus (CpCSV, genus Polerovirus), beet western yellows virus (BWYV, genus Polerovirus), and soybean dwarf virus (SbDV, genus Luteovirus) was ...

Identification of New Chickpea Virus and Control of Chickpea Virus Disease. [PDF]

Evid Based Complement Alternat Med, 2022
Objective. The objective of the study was to discuss the classification, virus characteristics, detection methods, and control measures of chickpea virus, with an aim to provide a theoretical basis for identification of new chickpea virus and control of chickpea virus disease. Methods.

Beet Chlorosis Virus Infection Mitigates Aphid-Induced Plant Defences and Improves Plant Acceptability to Aphid Vectors. [PDF]

Mol Ecol
ABSTRACT Plant viruses often alter host traits in ways that affect interactions with herbivores, potentially facilitating their own acquisition and transmission by insect vectors. However, little is known about the molecular mechanisms underlying this phenomenon.

Distribution and identification of luteovirids affecting chickpea in Sudan [PDF]

, 2021
In Sudan yellowing viruses are key production constraints in pulse crops. Field surveys were carried out to identify luteovirids affecting chickpea crops in the major production regions (Gezira Scheme and River Nile State).

New persistent plant RNA virus carries mutations to weaken viral suppression of antiviral RNA interference. [PDF]

Mol Plant Pathol
Rice tiller inhibition virus 2, originating from wild rice, carries mutations at residues that are broadly conserved among poleroviruses, and these mutations weaken viral suppression of RNAi, allowing for persistent infection. Abstract Persistent plant viruses are widespread in natural ecosystems. However, little is known about why persistent infection

Recessive resistance against beet chlorosis virus is conferred by the eukaryotic translation initiation factor (iso)4E in Beta vulgaris. [PDF]

Plant Biotechnol J
Summary Eukaryotic translation initiation factors (eIFs) are important for mRNA translation but also pivotal for plant‐virus interaction. Most of these plant‐virus interactions were found between plant eIFs and the viral protein genome‐linked (VPg) of potyviruses.

Genetic diversity and recombination between turnip yellows virus strains in Australia [PDF]

, 2021
Disease outbreaks caused by turnip yellows virus (TuYV), a member of the genus Polerovirus, family Luteoviridae, regularly occur in canola and pulse crops throughout Australia.

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

Annals of Applied Biology, Volume 183, Issue 3, Page 200-208, November 2023., 2023
Turnip yellow virus (TuYV) is an important/damaging pathogen for brassicas, including oilseed rape (Brassica napus; A+C genomes). Annual UK losses of 67 million GBP have been estimated in oilseed rape; losses in mainland Europe must be much greater. Many resistant commercial varieties are available, however they are all based on the same resistance ...

A Protonated Cytidine Stabilizes the Ligand‐Binding Pocket in the PreQ1 Riboswitch in Thermophilic Bacteria

ChemBioChem, Volume 24, Issue 15, August 1, 2023., 2023
Riboswitches regulate the expression of bacterial genes in response to small molecular metabolites. In thermophilic bacteria these RNA structures have to withstand extreme temperatures. Here we show that a protonated cytidine nucleotide, as part of an intricate hydrogen bond network, is essential in maintaining the functional conformation of a preQ1 ...

Potential of publicly available Beta vulgaris germplasm for sustainable sugarbeet improvement indicated by combining analysis of genetic diversity and historic resistance evaluation

Crop Science, Volume 63, Issue 4, Page 2255-2273, July/August 2023., 2023
Abstract Sugar beet (Beta vulgaris L. ssp. vulgaris Doell.) was originally selected from white fodder beet in the 1780s and was then specifically bred for sucrose production. The relatively recent inception of the crop has led to a narrow genetic base that has bottlenecked sustainable improvement.
