Our research interests involve the material transports through the plant vascular system within a whole plant body. Our works have been on investigating the molecular pathways of protein and RNA transports through the phloem translocation stream and has provided significant insights into the role played by the plant vascular system regarding the long-distance transport of information macromolecules.

We utilize functional genomics, cell biology, physiological, molecular biological, and protein chemistry approaches to validate the role of these systemic signals that function to integrate root and shoot growth, under control and nutrient-stress conditions.
