  • Analysis of cell signaling during floral abscission in arabidopsis 

    Taylor, Isaiah (University of Missouri--Columbia, 2017)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The shedding of plant organs is known as abscission. Floral abscission in Arabidopsis is regulated by two related receptor[negation symbol]-like protein ...

  • From plant to the pump : how plant genome research at MU is helping to achieve bioenergy goals 

    Walker, John C. (2009)
    Part of America's answer to the current energy crisis could be fuels made from plants. Fuel made from plant materials, such as cellulose or corn kernels, not only holds promise of reducing our nation's dependence on foreign ...

  • The function of the fork-head-associated domain in Arabidopsis thaliana [abstract] 

    Pursel, Sydney; Chevalier, David; Walker, John C. (University of Missouri--Columbia. Office of Undergraduate Research, 2007)
    Protein-Protein interactions are one of the elements of regulating signaling and cellular processes. These interactions are mediated between interaction domains and target motifs. The interaction domains bind specific ...

  • Functional analysis of MAP kinases in Arabidopsis thaliana: Fully rescuing the mpk3/mpk6 mutant phenotypes 

    Ngwenyama, Njabulo; Wang, Huachun; Liu, Yidong; Walker, John C.; Zhang, Shuqun, 1970- (University of Missouri--Columbia. Office of Undergraduate Research, 2005)
    Mitogen Activated Protein Kinase (MAPK) cascades are three-stage modules involved in signal transduction. MAPKs function at the lower tier of these cascades and they phosphorylate transcription factors and other protein ...

  • Genetics and functional genomics of abscission 

    Niederhuth, Chad E., 1985- (University of Missouri--Columbia, 2013)
    Abscission is the shedding of plant organs as part of development or in response to environmental stresses. In the model plant Arabidopsis thaliana, only the floral organs abscise as part of development. This is controlled ...

  • Genotypic analysis of receptor-like protein kinases with leucine-rich repeat motifs 

    Davis, Melissa; Chevalier, David; Walker, John C. (University of Missouri--Columbia. Office of Undergraduate Research, 2004)
    Receptor-like protein kinases (RLKs) are transmembrane proteins that transmit extracellular signals across a membrane with the use of an intracellular kinase domain. RLKs play important roles in plant growth and development, ...

  • Haplo-Insufficiency of MPK3 in MPK6 Mutant Background Uncovers a Novel Function of These Two MAPKs in Arabidopsis Ovule Development 

    Wang, Huachun; Liu, Yidong; Bruffet, Kristin; Lee, Justin; Hause, Gerd; Walker, John C.; Zhang, Shuqun, 1970- (American Society of Plant Biologists, 2008)
    The plant life cycle includes diploid sporophytic and haploid gametophytic generations. Female gametophytes (embryo sacs) in higher plants are embedded in specialized sporophytic structures (ovules). Here, we report that ...

  • Pathogen susceptibility to Pseudomonas syringae in Arabidopsis thaliana [abstract] 

    Pursel, Sydney; Valdivia, Elene; Kim, Sang Hee, 1975-; Gassmann, Walter, 1964-; Walker, John C. (University of Missouri--Columbia. Office of Undergraduate Research, 2008)
    Peptides may act as regulatory molecules that coordinate cellular responses needed for growth, differentiation and development. A novel family of small peptides, encoded by the DEVIL (DVL) gene family, was identified in a ...

  • Peptidomics of Arabidopsis thaliana 

    Jemes, Paula; Lease, Kevin; Walker, John C. (University of Missouri--Columbia. Office of Undergraduate Research, 2005)
    Peptidomics is study of all the peptides in an organism, some of which are signaling molecules. Peptides are polymers of amino acids. For the purpose of this work, peptides are defined as proteins being less than 15 kDa ...

  • Protein phosphorylation regulation in Arabidopsis 

    Wang, Huachun (University of Missouri--Columbia, 2006)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Protein phosphorylation and dephosphorylation are fundamental mechanisms involved in many cell-signaling events. Coordinated actions of protein kinases ...

  • Regulation of floral organ abscission in Arabidopsis thaliana 

    Cho, Sung Ki; Larue, Clayton T., 1977-; Chevalier, David; Wang, Huachun; Jinn, Tsung-Luo; Zhang, Shuqun, 1970-; Walker, John C. (The National Academy of Sciences of the USA, 2008)
    Abscission is a developmental program that results in the active shedding of infected or nonfunctional organs from a plant body. Here, we establish a signaling pathway that controls abscission in Arabidopsis thaliana from ...

  • Regulation of plant development in Arabidopsis 

    Larue, Clayton T., 1977- (University of Missouri--Columbia, 2008)
    [ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The development of a complex organism, such as a plant, requires the function of multiple pathways that regulate various aspects of the developmental ...
