Image Number D2847-1

This scanning electron micrograph of grapevine xylem highlights the tubes that carry water and nutrients throughout the plant. The middle yellow section is a bridge that connects the two larger xylem vessels. These bridges increase the connectivity of the xylem transport system, differ in number and structure between grapevine species, and may play an important role in the spread of disease-causing pathogens.
