Light-Related Photosynthetic Gene Expression And Enzyme Activity In The Heterokont Alga Vaucheria Litorea And Its Symbiotic Partner The Sacoglossan Mollusc Elysia Chlorotica, Kara M. Soule

Electronic Theses and Dissertations

Photosynthesis is comprised of tightly coupled reactions and therefore requires strict matrices of regulation, particularly involving alterations in gene expression and enzyme activity within the nucleus and plastid. Extensive research has been carried out on these light-regulated mechanisms in plants and green algae, however, much less is known in the red algal lineage, including heterokonts. The goal of this study was to investigate the influence of light on photosynthetic gene expression and select enzyme activity in the heterokont alga Vaucheria litorea and its symbiotic partner Elysia chlorotica, a photosynthetic sacoglossan mollusc (sea slug). Elysia chlorotica harbors V. litorea plastids …
