  • Regulation by male-specific fruitless of neural circuitry used during courtship and copulation behavior in Drosophila melanogaster

    Creator:
    Latham, Kristin Lynn
    Abstract:
    Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...

  • Origins and evolution of plant microRNA genes

    Creator:
    Fahlgren, Noah
    Abstract:
    Eukaryotic small RNA (~20-30 nucleotides) are diverse regulatory molecules that repress gene expression at the transcriptional and post-transcriptional levels, defend hosts against invading viruses and defend genomes against selfish DNA elements. Small RNA populations are studied by high-throughput sequencing of the total small RNA fraction isolated from cells, however, the...

  • Small RNA pathways in plants

    Creator:
    Montgomery, Taiowa A.
    Abstract:
    miRNA-guided cleavage initiates entry of primary transcripts into the trans-acting siRNA (tasiRNA) biogenesis pathway involving RNA-DEPENDENT RNA POLYMERASE6 (RDR6), DICER-LIKE 4 (DCL4), and SUPPRESSOR OF GENE SILENCING3 (SGS3). Arabidopsis thaliana TAS1 and TAS2 families yield tasiRNA that form through miR173- guided initiation cleavage on the 5’ side of the siRNA-generating...

  • Endogenous and antiviral RNA silencing pathways in Arabidopsis

    Creator:
    Chapman, Elisabeth J.
    Abstract:
    RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

  • The proteomic and transcriptomic responses to iron, sulfur, and nitrogen limitation in the abundant marine bacterium Candidatus Pelagibacter ubique

    Creator:
    Smith, Daniel P.
    Abstract:
    Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...

  • Rapid evolution of post-transcriptionally regulated RESTORER OF FERTILITY-LIKE genes in the genus Arabidopsis

    Creator:
    Jogdeo, Sanjuro
    Abstract:
    The Pentatricopeptide Repeat (PPR) gene family produces RNA-binding proteins that target organellar transcripts. The PPR family is expanded in land plants, with nearly 450 genes identified in Arabidopsis thaliana. In plants with a Cytoplasmic Male Sterility (CMS) phenotype, members of the PPR family can act as a RESTORER OF FERTILITY...

  • 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...

  • Transcriptional networks controlled by the fatty acid regulators FAR-1 and FAR-2

    Creator:
    Bredeweg, Erin L.
    Abstract:
    Fungi are capable of growth on a wide variety of carbon sources, both living and dead. They can produce an arsenal of enzymes and transporters for harvesting sugars, polysaccharides, amino acids, lipids and micronutrients from their environments [1]. Within the nucleus of a cell, transcription factors (TF) control whether genes...
