Abstract
Intercellular communication of plant cells is held by plasmodesmata (PD). PD form cytoplasmic continuity and some macromolecules move through them. PD components and mechanism of macromolecule transport are still unclear. On the other hand, plant viruses utilize PD as paths to invade cells. Movement protein (MP) of tobamovirus is localized in branched PD in leaves and increases the size exclusion limit.
It is likely that MP interacts with PD proteins, which are involved in macromolecule transport. To identify such proteins, we analyzed cell wall proteins co-extracted with MP using leaves of transgenic tobacco expresssing MP. Out of these proteins, 24K germin like protein and 42K polygalacturonase β-subunit homolog protein were analyzed further. This time, we report about the detail localization of these proteins.
