  4. 2. Plant-associated soil communities : Patterns, drivers and aboveground consequences

    Author : Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aboveground-belowground interactions; arbuscular mycorrhiza; climate; dispersal; environmental drivers; fungi; genetic variation; nematodes; plant-herbivore interactions; soil communities; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Abstract : Soil contains a wealth of diversity – bacteria, fungi, nematodes, arthropods and earthworms are just some of the many organisms found belowground. These organisms play an important role in shaping the soil environment and they strongly influence plant fitness, diversity and community composition. READ MORE

    Abstract : Listeria monocytogenes is a ubiquitous foodborne Gram-positive bacterium. Despite being mainly a soil bacterium, it can reach the food processing environment and contaminate food destined for human consumption, causing outbreaks. READ MORE

  6. 4. Ammonia-Oxidising Bacteria in Soil : Studies of diversity and abundance using 16S rRNA gene analysis

    Author : Anna Hermansson; Janet Jansson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nitrification is the process whereby ammonia is oxidised to nitrate. The first step of this process is carried out by the chemoautotrophic, ammonia-oxidising bacteria (AOB), which convert ammonia to nitrite. READ MORE

  7. 5. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A

    Author : Ann Lövgren; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Abstract : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. READ MORE
