I am a biochemist and molecular biologist currently dedicated to researching proteins within the bacterium Xanthomonas citri subsp. citri (X. citri). This bacterium is the primary cause of citrus canker—a disease, which affects citrus plants. The proteins in X. citri, which I am studying, are intriguing because their functions remain unknown; yet, they play a significant role in the interaction between this bacterium and citrus plants. My research approach involves the generation of mutants through site-directed mutagenesis. These mutants are then subjected to comprehensive analysis using a combination of genetic, biochemical and morphological techniques. Through these investigations, I aim to uncover the precise functions and mechanisms of these proteins, shedding light on their role in the complex interaction between X. citri and citrus plants.
