The Effect Of Kalanchoe Pinnata On The Cell Migration Of Astrocytomas, Jorge Rosa Jun 2018

The Effect Of Kalanchoe Pinnata On The Cell Migration Of Astrocytomas, Jorge Rosa

The International Student Science Fair 2018

Astrocytomas, from cell line 1321N1,are cancerous astrocytes. These are a type of glial cell in the brain which is responsible for maintaining synaptic contact and the signaling capacities among neurons. They also represent a fundamental element in controlling blood flow and defining brain micro structure. Due to the fact that this variant is cancerous, a condition commonly described as an abnormal cell cycle and uncontrolled reproduction of cells, they have the ability to metastasize.

In the metastatic process of cancer cells the initial phase is know as tumor invasion. This stage consists mainly of the cells migrating away from the …

Plant Biodiversity In The Face Of Climate Change: What Will Become Of Coastal Endemic Species?, Nila Le Apr 2018

Plant Biodiversity In The Face Of Climate Change: What Will Become Of Coastal Endemic Species?, Nila Le

Creative Activity and Research Day - CARD

How will longitudinally constrained coastal flora fare in the face of rapid anthropogenic climate change and disturbance? Coastal communities pose a unique problem for climate change and its associated risks. Species that are concentrated along the coast are naturally vulnerable to the influence of harsh abiotic ecology, such as coastal erosion and high salt concentrations. In addition, analogous to montane species-habitat interactions, coastal communities may be “pushed” off the coast edge as a result of tracking preferred climate in the face of climate variability and sea level rise. This can be problematic for species that cannot disperse quickly enough to …


Constitutive Expression Of Thioglucoside Glucohydrolase 1 (Tgg1) Decreases Intercellular Trafficking In Arabidopsis Thaliana, Alessandro Francesco Sarno Apr 2018

Constitutive Expression Of Thioglucoside Glucohydrolase 1 (Tgg1) Decreases Intercellular Trafficking In Arabidopsis Thaliana, Alessandro Francesco Sarno

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Plasmodesmata (PD) are pores that traverse plant cell walls, providing a route for intercellular trafficking of essential metabolites, nutrients, and signaling molecules between adjacent plant cells, thereby aiding communication. The increased size exclusion limit 2 (ise2) mutant of Arabidopsis thaliana has an increased abundance of branched PD, as well as a greater flux of intercellular trafficking. A search for proteins that interact with ISE2 identified THIOGLUCOSIDE GLUCOHYDROLASE 2 (a myrosinase). A. thaliana also encodes a second, closely-related myrosinase, TGG1. Myrosinases are enzymes that catalyze the hydrolysis of glucosinolates, a type of secondary metabolite that are amino acid derivatives. The breakdown …


Evaluating Effects Of Gene Mutation And Light Intensity On Arabidopsis Thaliana Development, Carolanne Bekus Apr 2018

Evaluating Effects Of Gene Mutation And Light Intensity On Arabidopsis Thaliana Development, Carolanne Bekus

Student Scholar Showcase

The completion of sequencing Arabidopsis thaliana’s genome has led to the next crucial challenge of determining gene function in these plants. A. thaliana is a model organism often compared to commercial crops. The discovery of gene function within these plants will aid in giving insight on how gene function can affect commercial crop production. Presented here is an analysis comparing wild-type Columbia (Col-O), to single gene mutants when knocking-out transcriptional factors VPI/ABI3-like 1 (val1) and basic region/leucine zipper motif (bZIP). These single gene mutations may affect several traits that in turn can result in morphological changes and/or …


Does The Fungal Pathogen (Botryosphaeria Dothidea) Exceed The Dehydration Tolerance Of Its Chaparral Host?, Cristian M. Garcia Mar 2018

Does The Fungal Pathogen (Botryosphaeria Dothidea) Exceed The Dehydration Tolerance Of Its Chaparral Host?, Cristian M. Garcia

Seaver College Research And Scholarly Achievement Symposium

We tested the hypothesis that an opportunistic endophytic fungus Botryosphaeria dothidea that frequently infects and causes dieback in several different species of chaparral shrubs in the Santa Monica Mountains continues to elongate and grow in host tissues at dehydration levels that exceed host survival. This was done by collecting several large branches from the field from three dominant species of co-occurring chaparral shrubs, Malosma laurina, Ceanothus spinosus, and Ceanothus megacarpus. We allowed branches to dehydrate at increasing lengths of time, from a few days to one week, in an air-conditioned laboratory, then sealed in plastic bags to allow tissuewater equilibration, …


Testing For The Presence Of Botryosphaeria Dothidea In Branches Of Ceanothus Spinosus Undergoing Dieback, Katarina Carter Mar 2018

Testing For The Presence Of Botryosphaeria Dothidea In Branches Of Ceanothus Spinosus Undergoing Dieback, Katarina Carter

Seaver College Research And Scholarly Achievement Symposium

Botryosphaeria dothidea is an opportunistic pathogen found in some of the cavitated branches of the chaparral vegetation in the Santa Monica Mountains. In this study, we focused on investigating the presence of Botryosphaeria dothidea in Ceanothus spinosus located on Pepperdine University’s campus. We wanted to test this hypothesis because we had observed a large amount of dieback in the Ceanothus spinosus population and wanted to identify a possible contributor. Because of the large number of cavitated branches in the Ceanothus spinosus we tested, we hypothesized that they contained fungus. To test this, we took twenty samples of twenty different Ceanothus …
