  • Molecular cloning and characterization of the diageotropica gene in tomato (Lycopersicon esculentum Mill.)

    Creator:
    Oh, KwangChul
    Abstract:
    The auxin-resistant diageotropica (dgt) mutant of tomato (Lycopersicon esculentum Mill.) has a pleiotropic phenotype including a lack of lateral roots and reduced gravitropic response, apical dominance, vascular development, and fruit growth. The dgt mutation reduces the auxin sensitivity of only a subset of auxin responses while levels, metabolism, and transport...

  • Characterization of Neurospora crassa and Fusarium graminearum mutants defective in repeat-induced point mutation

    Creator:
    Pomraning, Kyle R.
    Abstract:
    Mutation of repetitive DNA by repeat-induced point mutation (RIP) is a process that occurs in many filamentous fungi of the Ascomycota during the sexual cycle. Concurrently, direct DNA repeats are often deleted by homologous recombination at high frequency during the sexual cycle. Thus, the processes of RIP and deletion compete...

  • Phylogenetic Studies in Tenebrionidae (Coleoptera) and Related Families

    Creator:
    Kanda, Kojun
    Abstract:
    In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

  • 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...

  • Nuclear and mitochondrial DNA polymorphism and phylogeny in the California closed-cone pines

    Creator:
    Wu, Junyuan
    Abstract:
    We studied genetic polymorphism and phylogeny using nuclear random amplified polymorphic DNA markers (RAPDs) and mitochondrial DNA (mtDNA) restriction fragment length polymorphisms (RFLPs) in the three California Closed-Cone Pines: Pinus attenuata Lemm., P. muricata D. Don, and P. radiata D. Don. A total of 343 to 384 trees derived from...

  • Plastome phylogenomics in the genus Pinus using massively parallel sequencing technology

    Creator:
    Parks, Matthew Benjamin
    Abstract:
    This thesis summarizes work completed over the previous four years primarily focusing on chloroplast phylogenomic inquiry into the genus Pinus and related Pinaceae outgroups using next-generation sequencing on Illumina platforms. During the time of our work, Illumina sequence read lengths have essentially been limited to 25 to 100 base pairs,...

  • 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...

  • Alternative splicing in the obligate biotrophic oomycete pathogen, Pseudoperonospora cubensis

    Creator:
    Cumbie, Jason S.
    Abstract:
    Oomycetes are some of the most devastating pathogens, causing upwards of billions of dollars of damage each year to plants. They also diminish ecological diversity and health through the destruction of trees and shrubs. The genome sequence of Pseudoperonospora cubensis, an obligate plant pathogen and causative agent of downy mildew...

  • Pyrenophora tritici-repentis : investigation of factors that contribute to pathogenicity

    Creator:
    Holman, Thomas W.
    Abstract:
    Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...
