A majority of soil carbon (C) is either directly or indirectly derived from fine roots, yet roots remain the least understood component of the terrestrial carbon cycle. The decomposability of fine roots and their potential to contribute to soil C is partly regulated by their tissue chemical composition. Roots rely heavily on heteropolymers such as suberins, lignins and tannins to adapt to various environmental pressures and to maximize their resource uptake functions. Since the chemical construction of roots is partly shaped by their immediate biotic/abiotic soil environments, global changes that perturb soil resource availability and plant growth could potentially alter …

The Summer Undergraduate Research Fellowship (SURF) Symposium
The shikimate pathway is a metabolic pathway that produces the three aromatic amino acids—phenylalanine, tryptophan, and tyrosine—which are essential to human diets and necessary for many plant functions. Consequently, the shikimate pathway is commonly targeted for antibiotic and herbicide strategies as well as genetic engineering in several fields. This pathway is known to be localized in the plastids, or double membrane-bound organelles, of plant cells; however, there is enzymatic evidence of another shikimate pathway in the cell fluid, or cytosol. To determine whether a complete cytosolic shikimate pathway exists, we used a modified gene for the first enzyme of the …
