  • Quorum-sensing-controlled public goods in Pseudomonas aeruginosa : regulation and application

    Creator:
    Mellbye, Brett L.
    Abstract:
    Cell-to-cell communication by chemical signals, termed quorum sensing (QS), is a common regulatory scheme in the microbial world. Pseudomonas aeruginosa¸ an opportunistic pathogen of burn wounds and cystic fibrosis lungs, uses QS to control the expression of hundreds of genes, particularly those necessary for population level benefits such as biofilm...

  • Genetic dissection of Victoria blight disease susceptibility in Arabidopsis thaliana

    Creator:
    Sweat, Teresa A.
    Abstract:
    The fungus Cochliobolus victoriae causes Victoria blight of oats and Arabidopsis and is pathogenic due to its production of a compound called victorin, which induces programmed cell death in sensitive plants. Victorin sensitivity in Arabidopsis is conferred by the dominant gene LOCUS ORCHESTRATING VICTORIN EFFECTS1 (LOV1), which encodes a coiled-coil-nucleotide...

  • Processing and functional diversity of plant microRNA

    Creator:
    Cuperus, Josh
    Abstract:
    RNA interference pathways can involve amplification of secondary siRNAs by RNA-dependent RNA polymerases. In plants, RDR6-dependent secondary siRNAs, including transacting siRNAs (tasiRNAs), arise from transcripts targeted by some microRNAs (miRNAs). In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)-miR390 complexes interact with primary transcripts at two sites, resulting in recruitment...

  • Recombination, resistance, and drug discovery in Chlamydia

    Creator:
    Sandoz, Kelsi
    Abstract:
    The intracellular life cycle of Chlamydia has been difficult to study due to the inability to genetically manipulate the bacteria. As a result, indirect methods have been employed to study the pathogen and the aspects that contribute to its unique intracellular life cycle. A wide variety of laboratory adapted strains,...
