Semaphorin-Induced Plasticity In The Nervous System Of The Cricket, Gryllus Bimaculatus, Alicia G. Edwards
Semaphorin-Induced Plasticity In The Nervous System Of The Cricket, Gryllus Bimaculatus, Alicia G. Edwards
Honors Projects
The adult auditory system of the cricket, Gryllus bimaculatus, exhibits a rare example of neuronal plasticity. Upon deafferentation, we observe medial dendrites that normally respect the midline of the PTG in the central nervous system sprouting across the boundary and forming synaptic connections with the contralateral auditory afferents. The Horch Lab has investigated key molecular factors that might play a causal role in this paradigm. Specifically, the protein Sema1a.2 comes from a guidance molecule family and has a role in developmental neuronal plasticity in other organisms. In this study, I explored the role of Sema1a.2 in the neuronal plasticity of …
Genetic Analysis Of Cellular Adhesion In Arabidopsis Thaliana, Andrew Close Bolender
Genetic Analysis Of Cellular Adhesion In Arabidopsis Thaliana, Andrew Close Bolender
Honors Projects
Plant cell adhesion is mediated by the extracellular matrix (ECM) or cell wall and plays an important role in plant morphogenesis and development. The amount, modification, and cleavage of pectin in the cell wall are major contributors to the adhesive properties of the ECM. To gain a more complete picture of plant cell adhesion processes, Arabidopsis thaliana seedlings were previously mutagenized and screened for hypocotyl adhesion defects. Genomic sequencing of one plant exhibiting an adhesion defect, isolate 242, showed that two mutations, one in cellulose synthase (CesA1) and another in a sugar transporter, are candidates for the causative mutation. This …
