    Abstract : Common bean (Phaseolus vulgaris L.) is an important export crop in Kyrgyzstan since the end of the 20th century. Kyrgyzstan produces about 70,000 t of common beans per year, which provides jobs to 76% of the population in the Talas region. READ MORE

  4. 2. Diversity and interactions of begomoviruses and their associated DNA-satellites

    Author : Muhammad Naeem Sattar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : To study the diversity of begomovirus/DNA-satellite complexes, plants of one crop species (okra; Abelmoschus esculentus) and one weed species (Ageratum conyzoides), both with leaf curling symptoms, were analyzed. Sequence analyses of complete genome components revealed a unique begomovirus/DNA-satellite complex in both plants. READ MORE

    Abstract : During the last decades, spraing disease caused by Potato mop-top virus (PMTV) has become a severe problem in the potato production throughout the Nordic countries. In this thesis, it was shown that PMTV is widely distributed throughout Sweden, Norway and Denmark, and has now become prevalent in the potato-production areas within these countries. READ MORE

  6. 4. Molecular epidemiology of begomoviruses that infect vegetable crops in southwestern Cameroon

    Author : Walter Nkeabeng Leke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Begomoviruses are plant-infecting viruses, which are transmitted by the whitefly vector Bemisia tabaci. They have a genome of single-stranded DNA that consists of either a single (monopartite) or two components (bipartite) with a component size of approximately 2.8 kb. READ MORE

  7. 5. Microorganisms in the atmosphere

    Abstract : Bacteria are present everywhere around us; in water, soil, food, on our skin, and in the air we breathe, mainly as parts of aerosols (i.e. minute air-suspended particles). Aerosols are mainly composed of sea salt, dust, sulphates and soot but some also contain bacteria, virus, pollen, plant debris and organic matter (i. READ MORE
