  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. Detection of poleroviruses causing virus yellows in sugar beet

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Josefin Pettersson; [2020]
    Nyckelord :beet chlorosis virus; beet mild yellowing virus; sugar beet; Sweden; turnip yellows virus;

    Sammanfattning : Sugar beet is a crop cultivated for production of sugar. Many diseases can cause yield loss of sugar beet, where some are caused by viruses. Virus yellows is caused by several viruses and is visible as yellowing of sugar beet leaves. These viruses are transmitted by aphids and can be found across the world in temperate regions. LÄS MER

  4. 3. 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

  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
