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

   University essay from SLU/Department of Plant Biology (from 140101)

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

   Abstract : 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. READ MORE

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

   University essay from SLU/Dept. Of Plant Biology

   Author : Marcelle Lauren Johnson; [2019]
   Keywords : barley; BYDV; luteovirus; polerovirus; Skåne; wheat;

   Abstract : 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). READ MORE

   University essay from SLU/Department of Plant Biology (from 140101)

   Author : Asmaa Youssef; [2017]
   Keywords : Potato tuber necrotic ringspot disease; Potyvirus; PVY strains; recombination; virus detection; virus taxonomy;

   Abstract : Potato virus Y (PVY) is the most important and widespread virus infecting potato (Solanum tuberosum) worldwide. Recently, new PVY recombinant genotypes have emerged and their incidence is increasing throughout the world. READ MORE

5. 4. Wheat dwarf virus : interaction with ancestors of wheat

   University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

   Keywords : geminivirus; mastrevirus; Psammotettix alienus; Triticum aestivum;

   Abstract : Among the wheat diseases, wheat dwarf caused by Wheat dwarf virus (WDV) has resulted in damage to wheat production in the past years. This virus from the family Geminiviridae and genus Mastrevirus is transmitted by the leafhopper Psammotettix alienus. READ MORE

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

   University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

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

   Abstract : 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.
