  1. 1. Analysis of winter wheat and leafhoppers for wheat dwarf virus : factors causing outbreaks of wheat dwarf disease

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Plant Biology (from 140101)

    Författare :Lina Karm Togo; [2024]
    Nyckelord :Sweden; Psammotettix alienus; DAS-ELISA; cloning; sequencing; BLASTn; BLASTx; MEGA; SDT;

    Sammanfattning : Wheat dwarf disease is caused by wheat dwarf virus (WDV) and is transmitted by the leafhopper Psammotettix alienus. The disease has been reported in many European countries, as well as in West Asia, China, and one country in North Africa. LÄS MER

  3. 2. Analyses of circular DNA molecules in the leafhopper Psammotettix alienus for identification of viruses and plasmids

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Jeremiah Sigalla; [2019]
    Nyckelord :blue dwarf disease; leafhopper; phylogenetic analysis; psammotettix alienus; rolling circle amplification; wheat blue dwarf phytoplasma; wheat dwarf disease; wheat dwarf virus;

    Sammanfattning : Microorganisms often depend on vectors for transmission. A single vector may carry different species of microorganisms such as fungi, bacteria and viruses. In Sweden, leafhoppers of the species Psammotettix alienus are known as a vector of wheat dwarf virus, but they may be carriers of other microorganisms as well. 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. Characterisation of Wheat dwarf virus isolates from the vector Psammotettix alienus

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

    Författare :Louise Lidemalm; [2013]
    Nyckelord :diversity; leafhopper; PCR; phylogenetic analysis; Psammotettix alienus; rolling circle amplification; sequence; vector; wheat; wheat dwarf disease; Wheat dwarf vector; whole genome amplification;

    Sammanfattning : Wheat dwarf disease caused by Wheat dwarf virus (WDV) can cause a lot of damage in wheat fields by reduction of yield. WDV belongs to the genus Mastrevirus in the family of Geminiviridae and it is transmitted by the leafhopper Psammotettix alienus. LÄS MER
