Webb1. INTRODUCTION. For plant viruses, the vascular phloem represents a key obstacle in establishing an infection. It serves as both a mechanical and physiological barrier, creating a unique environment that functions in the transport of a diverse set of molecules that includes sugars, lipids, amino acids, nucleic acids, proteins, and phytohormones (1–4). Phloem is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant.
