Isolating Bacteriophage For Potential Treatment Of Chronic Multi-Drug Resistant Escherichia Coli Infections, Leila Oswalt Jan 2022

Isolating Bacteriophage For Potential Treatment Of Chronic Multi-Drug Resistant Escherichia Coli Infections, Leila Oswalt

Honors Projects

The misuse and overuse of antibiotics has led to the intense rise in antibiotic resistance. As society transitions into the post antibiotic era, there will be a great need for new therapeutic strategies to address multiple drug resistant bacterial infections. One such method, called bacteriophage therapy, allows for specific targeting of certain pathogenic bacteria through the use of viruses that attack bacteria; termed “bacteriophage” or simply “phage”. Urinary tract infections are among the most common pathological human infections that rely heavily on the use of antibiotics, the major cause of which is the bacterium Escherichia coli. During the Spring 2021-Spring …


The Role Of Elmo5 In Arabidopsis Thaliana Cell Adhesion, Isabel Kristina Ball Jan 2022

The Role Of Elmo5 In Arabidopsis Thaliana Cell Adhesion, Isabel Kristina Ball

Honors Projects

Plant cell growth and development relies on proper cellular adhesion. As the extracellular matrix serves as the area of connection between two cells, its synthesis and maintenance are essential for cellular adhesion. The middle lamella region, the layer of the extracellular matrix between two adjacent cell walls, is diffuse with the polysaccharide pectin due to its delivery by Golgi vesicles early during cell division. A Ruthenium Red screen for cellular adhesion mutants identified the family of 5 ELMO proteins that are critical for proper cellular adhesion. To further our understanding of plant cellular adhesion and pathways of pectin synthesis and …


Characterization Of The Elmo2 Protein That Mediates Cell Adhesion In Arabidopsis Thaliana, Devaki Rajiv Jan 2022

Characterization Of The Elmo2 Protein That Mediates Cell Adhesion In Arabidopsis Thaliana, Devaki Rajiv

The binding of adjacent cells to one another, or cell adhesion, is critical for the growth and development of multicellular organisms. In plant cells, much evidence suggests that the amount and modification of pectin in the cell wall largely determines how well cell adhesion occurs. ELMO1 is a Golgi protein involved in pectin-mediated cellular adhesion, and mutations in ELMO1 lead to disrupted cell organization in Arabidopsis. ELMO1 is predicted to be a scaffold for pectin biosynthesis enzymes, and thus its absence leads to the adhesion-defective phenotype of elmo1-/- plants. There are four other ELMO homologues (ELMO2,3,4 and 5) which remain …


Genetic Analysis Of Adhesion Protein Elmo3 In Arabidopsis Thaliana, Garrison Asper Jan 2022

Genetic Analysis Of Adhesion Protein Elmo3 In Arabidopsis Thaliana, Garrison Asper

Honors Projects

The Extracellular Matrix (ECM) between plant cells is vital for structure, development, and intercellular adhesion. A pectin rich layer in between cells, the middle lamella, is largely responsible for regulating the adhesive properties of adjacent plant cells. Homogalacturonan (HG) pectin, the most common, is synthesized in the Golgi and secreted into the ECM where it undergoes calcium crosslinking, increasing its adhesive properties. Mutations in proteins essential for HG synthesis can reveal a severe adhesion defective phenotype, where the hypocotyls of dark grown Arabidopsis exhibit cell sloughing, curling, and general disorganization. A family of five ELMO proteins are suspected to act …


Mitigation Of Negative Effects Of Ocean Change On Oysters By Eelgrass And Its Implications For Aquaculture In Midcoast Maine, Fiona G. Ralph Jan 2022

Mitigation Of Negative Effects Of Ocean Change On Oysters By Eelgrass And Its Implications For Aquaculture In Midcoast Maine, Fiona G. Ralph

Species interactions are important to organisms and to the ecosystems they inhabit. These interactions, sometimes facilitations, can result in increased resiliency for both species. When facilitation occurs, organisms co-assist with physiological and environmental stressors. As anthropogenic impacts become more stressful for modern organisms, these interactions could offer a solution for many species. Ocean acidification has been shown to be detrimental to many calcifying organisms including oysters. More acidic conditions can slow the process of shell calcification, which can slow growth rates. This effect could directly impact the robust oyster farming business in Midcoast Maine. Because of its possible importance to …
