1. Molecular detection and characterization of begomoviruses from Burkina Faso and Nicaragua
Magister-uppsats, SLU/Dept. Of Plant BiologySammanfattning : Agriculture plays a major role in the economy of countries in Africa and America. Viruses have emerged as major plant pathogens during the last few decades on agriculturally important field crop plants. The genus Begomovirus belongs to the family Geminiviridae, which is the largest family of plant-infecting viruses. LÄS MER
2. RNA silencing suppression activity encoded by plant-infecting DNA satellites from Africa
Magister-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)Sammanfattning : Begomoviruses are whitefly-transmitted viruses, which can induce severe diseases in various vegetable, fiber and cereal crops around the world. Begomoviruses have a circular single-stranded (ss) DNA genome, and they often infect plants together with other circular ssDNA molecules, which are the so-called alphasatellites and betasatellites.

3. Molecular identification and characterization of begomoviruses in Nicaraguan cultivars of common beans
Kandidat-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)Sammanfattning : The production of common bean in Nicaragua is restrained by the occurrence of begomoviruses (family Geminiviridae; genus Begomovirus). Infections with viruses are known to cause yield loss every year, making them an important target for investigation. LÄS MER
4. A survey of cassava plants in the coastal region of Tanzania showing severe symptoms of cassava mosaic disease
Kandidat-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)Sammanfattning : Cassava (Manihot esculenta Crantz) is a root crop that plays an important role in many households in Africa. It is sometimes called “Africa´s food insurance”. The advantages with the crop are that cassava is drought-resistant and it can grow in a semi-dry land. It is a perennial crop and does not require much labor. LÄS MER
5. Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Kandidat-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)Sammanfattning : Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. LÄS MER
