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

    Virtual Internships: A COVID Side effect should Keep

    Author Name(s) Damaris Juarez Faculty Advisor(s) Elizabeth Blackwood Abstract For students at California State University Channel Islands (CSUCI) and the library that serves them, the pivot to online learning for the entirety of the 2020-2021 academic year disrupted the normal educational experience in myriad ways. CSUCI is a Hispanic Serving Institution, which serves many first-generation, non-traditional, and underserved students. Remote instruction separated many librarians from the needs of these students,… Read More »Virtual Internships: A COVID Side effect should Keep

    Range and conservation status of harlequin frogs and glass frogs

    Author Name(s) Siomara ZendejasJonathan AlvaradoJenny Juarez Faculty Advisor(s) Rudolf von May Abstract Given growing concern about worldwide amphibian population declines, it is critical to conduct continuous conservation status assessments to assist in species and habitat protection programs. In the study, we review the current data on geographic distribution, elevational range, and threat status of harlequin grogs (Atelopus) and glass frogs, two groups of Neotropical amphibians facing similar threats.Our main goal… Read More »Range and conservation status of harlequin frogs and glass frogs
