1. 1. Molecular detection of luteovirus and polerovirus : in oat, broad bean, soybean and aphids

   Kandidat-uppsats, SLU/Dept. Of Plant Biology

   Författare :Ellen Sköldberg; [2023]
   Nyckelord :barley yellow dwarf virus; bean leafroll virus; RT-PCR; food production; Sweden;

   Sammanfattning : Havre, åkerböna och sojabönor är alla vanliga och viktiga livsmedelsgrödor. De spelar en viktig roll över hela världen när det kommer till både näring och ekonomi. Liksom för de flesta växter kan de drabbas av olika sjukdomar, vilket orsakar ansenliga skördeförluster. Ett stort bekymmer är virusinfektioner i växter. LÄS MER

3. 2. Diversity of barley yellow dwarf-associated viruses in winter cereals of Southern Sweden

   Master-uppsats, SLU/Dept. Of Plant Biology

   Författare :Marcelle Lauren Johnson; [2019]
   Nyckelord :barley; BYDV; luteovirus; polerovirus; Skåne; wheat;

   Sammanfattning : Barley yellow dwarf virus (BYDV) is a widespread complex of virus species of cereal crops in the world, known to infect both wild and cultivated plants of the family Poaceae, having the effect of yield reductions and subsequently large economic losses to farmers. Barley yellow dwarf disease (BYD) is a result of infection from BYDV species (genus: Luteovirus) and cereal yellow dwarf virus (CYDV; genus: Polerovirus). LÄS MER

4. 3. Complete genome characterization of barley yellow dwarf virus-OYV

   Magister-uppsats, SLU/Department of Plant Biology (from 140101)

   Författare :Kanitha Sathees; [2016]
   Nyckelord :complete nucleotide sequence; genome organization; barley yellow dwarf virus-OYV BYDV-OYV ; Luteovirus; recombination;

   Sammanfattning : Barley yellow dwarf-associated viruses (BYD-associated viruses) belong to the family Luteoviridae and are of high economical relevance for cultivation of cereals. BYD-associated viruses are phloem-restricted pathogens that cause yellowing and reddening of leaves, plant dwarfing and reduction in size and number of grains. LÄS MER

5. 4. Sequence characterization of Barley yellow dwarf virus – OYV

   Master-uppsats, SLU/Department of Plant Biology (from 140101)

   Författare :Kanitha Sathees; [2015]
   Nyckelord :Barley yellow dwarf virus-OYV BYDV-OYV ; sequences; virus taxonomy; genome organization; phylogenetic analysis;

   Sammanfattning : Barley yellow dwarf (BYD)-associated viruses are economically important in a wide range of cereals and grasses worldwide. These viruses belong to family Luteoviridae and are efficiently transmitted by aphids in a circulative and non-propagative manner. BYD-associated viruses have a genome of single-stranded positive sense RNA (+ssRNA). LÄS MER

7. 5. Characterisation of virus isolates associated with leaf yellowing in Swedish sugar-beet plants

   Master-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

   Författare :Mohammad Nasir Uddin; [2010]
   Nyckelord :BMYV; sugar beet; coat protein; BtMV; isolates; sequences; phylogenetic analyses;

   Sammanfattning : Plants of sugar beet with symptoms of virus infection (mosaic and yellowing) were collected from Skåne in Sweden for virus identification and characterization. To test the presence of Beet mosaic virus (BtMV) several detection methods were applied, such as: mechanical inoculation/transmission test with sugar beet (Beta vulgaris), red beet (Beta vulgaris) cv Rubia, spinach (Spinacia oleracea) cv Long Standing Bloomsdale and lettuce (Lactuca sativa) cv Sonette; DAS-Enzyme-linked Immunosorbent Assay (DAS-ELISA) with polyclonal antibody; RT-PCR amplification with Potyviridae-specific universal primers Sprimer/M4 (Chen et al.
