Research Description

1. Investigation of Rubisco biogenesis and functionality. Genetic engineering of more active Rubisco in crops and trees to sequester more carbon dioxide (CO2) to biomass
2. DNA-based biotechnology to generate value-added plants that produce medicines and more nutrients, or become more tolerate to environmental stresses such as drought
3. Application of CRISPR technology for more precise gene editing and targeted metabolic engineering for new traits in plants
4. Application of nanotechnology for more efficient delivery of DNA, RNA or proteins to plant cells
5. Molecular ecology study of genetic variation and mechanisms for invasive plants and habitat shift in the Florida Everglades wetland
6. Detection and monitor of the citrus green disease causing bacterium CLas
