Viromes of Hungarian Peach Trees Identified by High-Throughput Sequencing of Small RNAs

open access: yesPlants, 2022
Peach trees can be infected with viruses and viroids. As we do not have efficient plant protection methods against these pathogens, the prevention of infection is crucial. Fruit trees are maintained by vegetative propagation.

Characterization of a New Wheat- 1M(1B) Substitution Line with Good Quality-associated HMW Glutenin Subunit [PDF]

open access: yes, 2016
In this study, a new substitution line, 12-5-1, with 42 chromosomes that was derived from BC3F2 descendants of the hybridization between Triticum aestivum cv. CN19 and Aegilops biuncialis was created and reported.

Distribution of Barley yellow dwarf virus-PAV in the Sub-Antarctic Kerguelen Islands and Characterization of Two New Luteovirus Species. [PDF]

open access: yesPLoS ONE, 2013
A systematic search for viral infection was performed in the isolated Kerguelen Islands, using a range of polyvalent genus-specific PCR assays. Barley yellow dwarf virus (BYDV) was detected in both introduced and native grasses such as Poa cookii.

Pyramiding of Ryd2 and Ryd3 conferring tolerance to a German isolate of Barley yellow dwarf virus-PAV (BYDV-PAV-ASL-1) leads to quantitative resistance against this isolate [PDF]

open access: yes, 2011
Barley yellow dwarf virus (BYDV) is an economically important pathogen of barley, which may become even more important due to global warming. In barley, several loci conferring tolerance to BYDV-PAV-ASL-1 are known, e.g.

Aphid vectors impose a major bottleneck on Soybean dwarf virus populations for horizontal transmission in soybean

open access: yesPhytopathology Research, 2019
Many RNA viruses have genetically diverse populations in a single host. Important biological characteristics may be related to the levels of diversity, including adaptability, host specificity, and host range.

Nucleotide Sequence of Potato Leafroll Luteovirus RNA

open access: yesJournal of General Virology, 1989
A sequence of 5987 nucleotides is reported for the RNA of potato leafroll luteovirus (PLRV). The sequence contains six large open reading frames, and non-coding regions of 174 nucleotides at the 5' end, 141 nucleotides at the 3' end and 197 nucleotides between two large blocks of coding sequences. The 5' coding region encodes two polypeptides of 28,000

Distribution and incidence of viruses in Irish seed potato crops [PDF]

open access: yes, 2015
peer-reviewedVirus diseases are of key importance in potato production and in particular for the production of disease-free potato seed. However, there is little known about the frequency and distribution of potato virus diseases in Ireland.
