Broad Spectrum Systemic Acquired Resistance In Amblystegium Serpens, Christina A. Tatara
Broad Spectrum Systemic Acquired Resistance In Amblystegium Serpens, Christina A. Tatara
Undergraduate Honors Thesis Collection
Systemic acquired resistance (SAR) is a well-characterized defense mechanism in vascular plants where initial exposure to a pathogen induces resistance throughout the plant to subsequent attacks by a wide range of pathogens. A similar SAR-like mechanism has recently been documented in a nonvascular plant, the moss Amblysregium serpens, but it has not been thoroughly characterized. Currently only one pathogen, the oomycete Pythium irregulare, has been shown to trigger SAR in this or any other nonvascular plant. I have observed and characterized the interactions between A. serpens and two other alleged moss pathogens, the ascomycetes Acrosporium sympodiale and Botrytis cinerea. Using …

Mutation And Complementation Of A Cellulose Synthase (Cesa) Gene, Ahmed Y. El-Araby
Senior Honors Projects
Cellulose is a carbohydrate polymer that is composed of repeating glucose subunits. Being the most abundant organic compound in the biosphere and comprising a large percentage of all plant biomass, cellulose is extremely plentiful and has a significant role in nature. Cellulose is present in plant cell walls, in commercial products such as those made from wood or cotton, and is of interest to the biofuel industry as a potential alternative fuel source. Although indigestible by humans, cellulose is nutritionally valuable, serving as a dietary fiber. Because of its ubiquity and importance in many areas, studying cellulose will prove to …
