Cellulose is a carbohydrate polymer that is composed of repeating glucose subunits. Being the most abundant organic compound in the biosphere and comprising a large percentage of all plant biomass, cellulose is extremely plentiful and has a significant role in nature. Cellulose is present in plant cell walls, in commercial products such as those made from wood or cotton, and is of interest to the biofuel industry as a potential alternative fuel source. Although indigestible by humans, cellulose is nutritionally valuable, serving as a dietary fiber. Because of its ubiquity and importance in many areas, studying cellulose will prove to …

Understanding the Importance of the zinc binding domain in the cellulose synthase complex: Some Assembly Required
Alfred Schupp
Sponsor: Alison Roberts, Biological Sciences
Cellulose microfibrils are vital components of the cell wall. A microfibril is made up of multiple strands of glucose chains, and these cellulose microfibrils are produced by protein complexes in the plasma membrane called cellulose synthase complexes, or CSCs for short. Each complex is made up of 36 subunits called Cellulose Synthase proteins, or CESAs. Each CESA produces a glucose polymer made from beta-1,4 glucan linkages. It is known that CESA proteins aggregate to form CSCs, and …

Plant cell walls are composed of a variety of carbohydrates, among them cellulose, pectin and hemicellulose. Cellulose is deposited in the cell wall as microfibrils via cellulose synthesis complexes (CSCs). These complexes contain the cellulose synthase proteins (CESAs) and come in two different morphological forms: rosettes and linear complexes. Rosette shaped cellulose synthesis complexes occur in land plants, whilst linear complexes are commonly found in red algae. However, some land plants, notably bryophytes (mosses) and seedless vascular plants, contain genes that encode both CESAs of the type that form rosette CSCs and also genes similar to those found in red …
The Herring River Estuary: Understanding Salt Marsh Restoration And How To Predict The Response Of Phragmites Australis To Increased Tidal Flow, Theresa Murphy
The Herring River Estuary: Understanding Salt Marsh Restoration And How To Predict The Response Of Phragmites Australis To Increased Tidal Flow, Theresa Murphy
Senior Honors Projects
My presentation invites you to learn about what is involved in planning a salt marsh restoration project. The Herring River Estuary is a disturbed salt marsh ecosystem at Cape Cod National Seashore which has been diked since 1909. The National Park Service (NPS), in cooperation with many partners, is engaged in efforts to restore the now impacted 1,100 acre estuary by re-introducing tidal flow. There is significant complexity involved in trying to restore such an intricate system- from the multitude of environmental factors to important social and economic consequences. There are also several benefits to restored tidal flow. My thesis …
