Intracellular protein transport in plants

Current Research

Although the major endomembranes of plant and animal cells are similar, there are three significant differences in the secretory pathway: a. plants do not possess a distinct ERGIC compartment, b. Golgi stacks in plants are dispersed throughout the cytoplasm, and do not disappear during mitosis,c. plants can have functionally distinct vacuoles e.g lytic (lysosome-like) and protein storage vacuoles. Our work centers on the mechanisms responsible for protein trafficking in plant cells. In particular we would like to learn how vacuolar storage proteins traverse the Golgi stack, and become sorted from other secretory proteins. We are also very interested in COP- and clathrin-coated vesicle- mediated events, especially in relation to endocytosis and vacuolar protein transport.
