  2. 11. Root-associated microbial communities of different strawberry cultivars as influenced by soil type, Verticillium dahliae Kleb. and biofumigation

    Author : Srivathsa Nallanchakravarthula; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Rhizosphere microorganisms and their interactions with plant roots play pivotal roles in controlling plant nutrition and health. Extremely high levels of soil microbial diversity, coupled with low levels of cultivability, complicate the study of these organisms but better mechanistic understanding of their interactions with each other and with plant roots is a prerequisite for development of sustainable management strategies to improve nutrient acquisition and control pathogens.

  4. 12. Friend or Foe? Biocontrol interactions of Pythium oligandrum within the potato cropping system

    Author : Christian Benjamin Andersen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The potato crop is a valuable but vulnerable food source on a global level. It is under constant pressure from destructive plant diseases such as early and late blight. Traditionally to control these diseases farmers have relied heavily on synthetic fungicide use. READ MORE

  5. 13. Priming of carbon and nitrogen mineralization in forest soils

    Author : Saeed Alaei; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil organic matter; C:N imbalance; root exudates; priming; Extracellular enzymes; Soil organic matter; C:N imbalance; root exudates; priming; Extracellular enzymes;

    Abstract : Decomposition of soil organic matter (SOM) contributes significantly to the global carbon (C) cycle and climate feedbacks. SOM decomposition depends on soil microbial activities, and these activities are driven by the availability of C and other nutrients. READ MORE

  6. 14. Genome-wide analyses of Bacillus amyloliquefaciens strains provide insights into their beneficial role on plants

    Author : Adnan Niazi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The innate immunity system of plants provides a basal defence barrier to most microorganisms. However, many plant pathogens have evolved to overcome this defence. Certain bacteria in the PGPB (plant growth promoting bacteria) category that improve plant growth have also been found to improve plant defence against insect pests and pathogens. READ MORE

  7. 15. Drivers of soil fungal communities in boreal forests : feedbacks on soil fertility and decomposition

    Author : Erica Sterkenburg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Boreal forests harbour diverse fungal communities with decisive roles in decomposition and plant nutrition. Difficulties in studying soil fungi have limited knowledge about how fungal communities are shaped. READ MORE
