Phenotypic Analysis of Medicago truncatula NPF1.7 Over-Expressing Plants Grown under Different Nitrate Conditions

Description: Plants have many nitrate transporters; in the model legume Medicago truncatula, MtNPF1.7 is among them. MtNPF1.7 is important for M. truncatula growth and it has been established that MtNPF1.7 is a high affinity nitrate transporter. M. truncatula plants with mutations in MtNPF1.7 gene show defects during plants growth, with striking abnormalities in nodule development and root architecture. Nitrogen fixation is an energy expensive process; when legumes have sufficient bioavailable nitrogen like… more

Evaluating the Role of UV Exposure and Recovery Regimes in PAH Photo-Induced Toxicity to Daphina Magna

Description: Polyaromatic hydrocarbons (PAHs) are contaminants synthesized through incomplete combustion of carbon based substances. PAHs are known to be photodynamic and toxicity increases exponentially when in contact with ultraviolet radiation (UV). The effect of UV absent recovery periods and potential for latent toxicity during photo-induced toxicity are previously unknown and are not included within the toxicity model. Results of equal interval tests further support the current reciprocity model as a … more

Neurological Responses to a Glucose Diet in Caenorhabditis elegans

Description: TRPV channels play a role in both mammalian insulin signaling, with TRPV1 expression in pancreatic beta-cells, and in C. elegans insulin-like signaling through expression of OSM-9, OCR-1, and OCR-2 in stress response pathways. In response to a glucose-supplemented diet, C. elegans are know to have sensitivity to anoxic stress, exhibit chemotaxis attraction, and display reduced egg-laying rate. Transcriptome analysis reveals that glucose stimulates nervous system activity with increased transcri… more

Generating Molecular Biology Tools to Investigate the Ca2+ Binding Ability of Arabidopsis TON2

Description: The position of the cell division plane in plants is determined by the position of the preprophase band. The pre prophase band (PPB) is a ring of microtubules centered around the nucleus on the inner side of plasma membrane that establishes the cortical division site. The PPB forms at the end of G2 and breaks down at the end of prophase leaving behind protein markers of its position that are collectively called the cortical division site. During cytokinesis the phragmoplast expands towards the … more

Delivery of CRISPR/Cas9 RNAs into Blood Cells of Zebrafish: Potential for Genome Editing in Somatic Cells

Description: Factor VIII is a clotting factor found on the intrinsic side of the coagulation cascade. A mutation in the factor VIII gene causes the disease Hemophilia A, for which there is no cure. The most common treatment is administration of recombinant factor VIII. However, this can cause an immune response that renders the treatment ineffective in certain hemophilia patients. For this reason a new treatment, or cure, needs to be developed. Gene editing is one solution to correcting the factor VIII muta… more

Investigating Human Gut Microbiome in Obesity with Machine Learning Methods

Description: Obesity is a common disease among all ages that has threatened human health and has become a global concern. Gut microbiota can affect human metabolism and thus may modulate obesity. Certain mixes of gut microbiota can protect the host to be healthy or predispose the host to obesity. Modern next-generation sequencing technique allows accessing huge amount of genetic information underlying microbiota and thus provides new insights into the functionality of these micro-organisms and their interac… more
