• Characterization of a recombinant inbred line population for quantitative trait locus mapping 

    Mayfield, Dustin; Grow, Edward; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2008)
    Eukaryotes can regulate gene expression by epigenetic mechanisms at the chromatin level. One epigenetically regulated gene in maize is Pl1-Blotched, an allele of purple plant1, which activates anthocyanin pigment production. ...
  • Chromatin-level regulation in maize [abstract] 

    Barber, Wesley; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2004)
    Epigenetic regulation of gene expression is determined by chromatin packing. Transcriptionally active genes are associated with open, less compacted chromatin, whereas transcriptionally less active or silent genes are found ...
  • Chromatin-level regulation of the maize purple plant1 gene 

    Shin, KyungJu. (University of Missouri--Columbia, 2008)
    In eukaryotes, gene expression is controlled at the chromatin level by mechanisms that are not yet well understood. This study addressed some of the unanswered questions about chromatin-level gene regulation. In maize, the ...
  • The effect of reduced chromatin gene expression on an epigenetically regulated maize gene 

    Schulte, Michael; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2005)
    In virtually all eukaryotic organisms, not just plants, genes are regulated at the level of chromatin. In a genomics approach to understand how expression of a gene can be regulated by its chromatin configuration, a series ...
  • The effects of histone acetylation on the maize allele PL1-blotched 

    Ladipo, Paul B. (University of Missouri--Columbia, 2007)
    Covalent modifications of DNA and nucleosomal histone proteins associated with eukaryotic chromatin have the potential to alter expression of a gene without change in its DNA sequence. One gene regulated through this ...
  • Fine-structure QTL mapping of suppressor of plant blotching1 in maize [abstract] 

    Grow, Edward; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2007)
    Suppressor of Plant Blotching 1, or Spb1, is a proposed epigenetic modifier of Pl-Blotched, an epi-allele that activates the synthesis of purple anthocyanin pigments in maize. Normally, Pl-Blotched causes a distinct ...
  • FISH transgene localization in hon102 and sgb101 transgenic maize [abstract] 

    McMurry, Joanne; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2007)
    My research project investigates the expression of transgenes within maize. Transforming maize with plasmid constructs that are intended to reduce chromatin gene expression by triggering RNA interference produces transgenic ...
  • Maize brace root formation and correlation with juvenile nodes and tassel structure [abstract] 

    Hardy, Dalena; Leach, Kristen; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2007)
    Global warming causing changes in weather patterns is making drought a more frequent occurrence. Drought is a major limiting factor of maize production worldwide. To maintain high production levels, it is important to ...
  • QTL mapping of suppressor of plant blotching1, modifiers of an epiallele [abstract] 

    Grow, Edward; Garcia, Sherry Flint; Cone, Karen Camille, 1952- (University of Missouri--Columbia. Office of Undergraduate Research, 2008)
    Pl1-Blotched is an epigenetically regulated allele (an epiallele) of the purple plant1 gene, which activates synthesis of purple anthocyanin pigments. We identified a modifier called Suppressor of plant blotching 1 (Spb1), ...
