Abstract: <p>The activities of phytohormones during the reproductive phase have been partially clarified in seed physiology while the biological role of plant hormones in oil accumulation during seed development has been investigated in part only. In this research, fatty acid (FA) contents and hormone profiles, including abscisic acid (ABA) and cytokinins (CKs) of seed samples in four different… more Full Text: THE INVOLVEMENT OF ENDOGENOUS PLANT HORMONES IN THE REGULATORY NETWORK OF FATTY ACID BIOSYNTHESIS IN SOYBEAN SEED A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in …

Abstract: <p>Based on an endogenous hormone study, three cytokinin type phytohormones; benzyladenine (BA), trans-zeatin (tZ) and methylthiol trans-zeatin (MeSZ), as well as abscisic acid (ABA) were exogenously added at three concentrations (10-7, 10-6 and 10-5 M) to cultures of Chlorella vulgaris in an attempt to alter growth rate, total lipid and fatty acid yields and fatty acid profile. Growth… more Full Text: HORMONAL ALGAE: A SOURCE OF FUNCTIONAL FATTY ACIDS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, …

Abstract: <p>This study assesses the ability of a unicellular protist, Euglena gracilis, to remove Cu and Ni from solution in mono- and bi-metallic systems. Living Euglena cells and non-living Euglena biomass were examined for their capacity to sorb metal ions. Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium characteristics of metal removal. In living systems… more Full Text: 1 Bioremoval of copper and nickel on living and non-living Euglena gracilis 2 3 4 5 A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master 6 of Science in the Faculty of Arts and Sciences 7 8 9 10 11 12 13 14 15 TRENT …

Abstract: <p>Arctic terrestrial ecosystems have experienced substantial structural and compositional changes in response to warming climate in recent decades, especially the expansion of shrub species in Arctic tundra. Climatic and vegetation changes could feedback to the global climate by changing the carbon balance of Arctic tundra. The objective of this thesis was to investigate the influence of… more Full Text: Carbon Exchange along a Natural Gradient of Deciduous Shrub Coverage in the Low-Arctic A dissertation submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Faculty of Arts …
