  3. 3. Selfish, mobile genes in honeybee gut bacteria

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Aleksei Põlajev; [2018]
    Keywords : lactobacillus kunkeei; transposon; transposase; mobile genetic element; pseudogenized; gut flora; symbiont; reduced genome; åland; gotland;

    Abstract : Transposons are selfish, mobile genetic elements, moving within the genome. The transposase genemakes this possible, as it codes for the enzyme that catalyzes the movement. In the case of bacteria,they can also move horizontally between individual bacteria, and sometimes even between species. READ MORE

  4. 4. Comparative genomics : understanding regulation ofhydrogenases in the nitrogen-fixing Frankia

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : Chatchai Kosawang; [2009]
    Keywords : Genomics; Hydrogenases; Nitrogen fixation; Frankia;

    Abstract : Frankia is a facultative symbiont actinomycete living with the dicotyledonousplant worldwide. Two hydrogenase functions- uptake hydrogenase and hydrogenevolvinghydrogenase- have been so far reported in Frankia species, while thepresence of [Fe] hydrogenase function was surmised. READ MORE
