An Innovative Approach to the Planet’s Degrading Environments: Engineering a Novel Strain of Rhizobacteria to Ensure Plant Productivity under Worsening Abiotic Stress Conditions

    Author Name(s) Selin KocalarAylin Salahifar Faculty Advisor(s) Edward Njoo Abstract To address environmental stressors such as heavy metal contamination, soil salinity, and rising temperatures, the relationship between rhizobacterial strain Bacillus cereus and survival of Arabidopsis thaliana under abiotic stress was probed and optimized through genetic engineering. Plant growth measurements, chlorophyll content studies by UV-visible spectrophotometry, profiles of 15 key metabolites using gas chromatography-mass spectroscopy, quantitative gene expression screens, and 1-aminocyclopropane-1-carboxylate… Read More »An Innovative Approach to the Planet’s Degrading Environments: Engineering a Novel Strain of Rhizobacteria to Ensure Plant Productivity under Worsening Abiotic Stress Conditions

    Comparative singlet oxygen photosensitizer efficiency of berberine, rose bengal, and methylene blue by time course nuclear magnetic resonance (NMR) monitoring of a photochemical 4+2 cycloaddition endoperoxide formation

    Author Name(s) Sarah SuKarthikha Sri IndranSohie PalEmma LeAnika ReganMeher JainAashi ShahDavid IglesiasAndrew WangEdward Njoo Faculty Advisor(s) Edward Njoo Abstract Berberine, a natural product alkaloid, has been shown to exert biological activity via in situ production of singlet oxygen, a highly reactive oxygen species, when photo irradiated. Berberine utilizes singlet oxygen in its putative mechanism of action, wherein it forms an activated complex with DNA and photosensitizes triplet oxygen to singlet… Read More »Comparative singlet oxygen photosensitizer efficiency of berberine, rose bengal, and methylene blue by time course nuclear magnetic resonance (NMR) monitoring of a photochemical 4+2 cycloaddition endoperoxide formation
