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.

Transformation of Nicotiana benthamiana with different BWYV (Beet western yellows virus) sequences to test for virus resistance [PDF]

Plant Cell, Tissue and Organ Culture, 2000
N. benthamiana plants were transformed by means of A. tumefaciens with either the viral replicase (ORF1/2), one of two smaller sequences involving the 5' and 3' ends (5'3'S and 5'3'AS) of the genome of BWYV or with the pBin19 vector alone (Kp). In total ca. 120 kanamycin (Km) resistant plantlets were generated. Of these 115 were positive by NPTII ELISA

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.

The presence of turnip yellows virus in oilseed rape (Brassica napus L.) in Serbia [PDF]

Pesticidi i Fitomedicina, 2016
A total of 86 oilseed rape samples from six crops in different localities were collected during 2014 and analyzed for the presence of Turnip yellows virus (TuYV), Cauliflower mosaic virus (CaMV) and Turnip mosaic virus (TuMV) using commercial double ...

New insights into virus yellows distribution in Europe and effects of beet yellows virus, beet mild yellowing virus, and beet chlorosis virus on sugar beet yield following field inoculation

Plant Pathology, Volume 70, Issue 3, Page 584-593, April 2021., 2021
The establishment of a 10% density method for virus yellows inoculation by viruliferous aphids in the field mimics natural infection and quick spreading induces representative yield effects. Abstract Beet yellows virus (BYV), beet mild yellowing virus (BMYV), beet chlorosis virus (BChV), and beet mosaic virus (BtMV) cause virus yellows (VY) disease in ...

Occurrence and distribution of sugar beet viruses in Lebanon

Phytopathologia Mediterranea, 2001
Field surveys were carried out in the main sugar beet growing areas of Lebanon to assess the occurrence and distribution of viral diseases. A total of 1002 samples from 115 commercial fields were serologically assessed for Beet Necrotic Yellow Vein ...

Viral Diseases of Cultivated Legume and Cereal Crops in Tunisia

Phytopathologia Mediterranea, 2007
A survey to identify virus diseases affecting legume (chickpea, faba bean and lentil) and cereal (bread and durum wheat and barley) crops at different locations in Tunisia was conducted in April, 2000. Thirty-eight legume fields (34 faba bean, 3 chickpea
