David Domozych is a plant cell biologist who studies the evolution of cell walls and their biosynthesis in plants. He is interested in the biochemistry and cell biology of cell wall polymers and other components of the extracellular matrix of the basal Streptophyta or charophytes, i.e., the extant group of green algae whose ancestors are the basal stock from which land plants evolved. Dr. Domozych's primary research tools include light, microscopy, confocal laser scanning microscopy and electron microscopy, immunocytochemistry, and multiple biochemical methodologies. His main subject of study is the model unicellular streptophyte, Penium margaritaceum. Currently, his research work is involved in answering questions such as:
- How do different cell wall polymers function during cell development? How do pectins and arabinogalactan proteins of the cell wall interact during cell expansion?
- How are various wall polymers processed in the plant Golgi Apparatus, packaged in specific vesicle types and transported to the cell surface? What are the molecular controls and signal transduction components of plant cell wall synthesis and secretion?
- What are the extracellular polymeric substances (EPS) of streptophyte algae? How are they produced and what are their functions?
He is also interested in the structural architecture and biosynthesis of the extracellular matrix of tomatoes, the development of root hairs in Arabidopsis and the molecular components/dynamics of the endomembrane system and secretory apparatus of plants.
Dr. Domozych's work has recently been sponsored by grants from the National Science Foundation's (NSF) Molecular and Cell Biology Program, NSF Integrated Organismal Systems and NSF Major Instrumentation Programs. Many students participate in his research program both during the academic year and summer.
