The Effects Of Jasmonic Acid And Chemicals In The Ja Pathway On The Defense Systems And Gene Expression In Moss, Physcomitrella Patens And Amblystegium Serpens, Allison Shanks
Undergraduate Honors Thesis Collection
Systemic acquired resistance (SAR) is a defense system used by plants that results in increased resistance to future pathogen infection following an initial pathogen exposure. SAR in vascular plants has been well documented; however, a similar defense system has only recently been documented in non-vascular plants. It is believed that chemicals in the jasmonic acid (JA) pathway are able to activate the SAR response in vascular plants. The non-vascular plant, Amb/ystegium serpens, will be used as a model to test if SAR is triggered by JA and two other molecules in the JA pathway, 12-oxo-phytodieonic acid, and methyl jasmonate. To …

euronal communication (synaptic transmission) is critical for nervous system function. This communication occurs at specialized junctions called synapses where chemical neurotransmitters signal from presynaptic to postsynaptic cells. Additional signaling via neuropeptide activated G protein-coupled receptors (GPCRs) fine-tunes synaptic communication. GPCRs are a large family of transmembrane receptor proteins that bind extracellular neurotransmitters and neuropeptides to activate intracellular signaling pathways. My project investigated the function of FSHR-l, a GPCR and potential neuropeptide receptor, in regulating synaptic transmission at the neuromuscular junction (NMJ) in Caenorhabditis elegans roundworms, which share conservation of nervous system structure and function with humans. Worms lacking the fshr-I …
