  1. 1. Effect of Touch on Cotton and Maize : influence on plant morphology and feeding preference in Spodoptera littoralis

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Anna Magnusson; [2022]
    Keywords : Mechanical stimuli; cotton; maize; thigmomorphogenesis; Spodoptera littoralis; induced defence; plant-plant interaction;

    Abstract : Plants are constantly exposed to touch and mechanical stimuli in natural environments, from rain, wind, animals and plant neighbours. However, current knowledge and understanding of how touch physiologically affects plants are limited. READ MORE

  3. 2. Effect of Aggregatibacter actinomycetemcomitans Leukotoxin on ATP Release through Pannexin Channels in Human Monocytes

    University essay from Umeå universitet/Institutionen för odontologi

    Author : Linnéa Bäck; Frykholm Jennie; [2016]
    Keywords : LtxA; ATP release; Aggregatibacter actinomycetemcomitans;

    Abstract : Aggregatibacter actinomycetemcomitans is strongly associated with aggressive periodontitis and one of several virulence factors is a leukotoxin (LtxA). The toxin has a consequential impact on human leukocytes which leads to an interference with the host ́s defences due to a chain reaction involving activation and release of a pro-inflammatory cytokine; interleukin-1β (IL-1β).

  4. 3. Predator-induced morphological defences in a freshwater snail

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Annelie Lagesson; [2011]
    Keywords : ;

    Abstract : The ability of a certain genotype to express different phenotypes depending on variations in the environment is called phenotypic plasticity. Predator induced defences are among the most studied and wide spread examples of phenotypic plasticity. READ MORE

  5. 4. Differences in exocuticle thickness in Leucorrhinia dubia (Odonata) larvae from habitats with and without fish

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Karin Olne; Ida Flenner; [2006]
    Keywords : Phenotypic plasticity; Morphological adaptations; Dragonflies; Cuticle thickness; Induced defences;

    Abstract : Many prey species are able to develop different morphological structures as defence against for example predators. Some of these structures are induced only by individuals exposed to a predator. This phenomenon is called phenotypic plasticity. READ MORE
