Understanding and regulation of xylem sap translocation between parasitic plants and host plants

Summary
Parasitic plants thrive by siphoning nutrients from host plants through vascular connections. Although these connections facilitate the bidirectional movement of various substances, the transport mechanisms are not well understood. This research investigates leaf transpiration to better grasp how parasitic plants extract xylem sap from host plants, to shed light on and possibly control this process.

Message

Parasitic plants, with their remarkable ability to connect their vascular systems to other plants, are fascinating. I am endlessly intrigued by their capabilities and eagerly anticipate conducting the planned experiments.

Outline of Research Achievments

I developed a monitoring system for leaf surface temperature by combining a single-board computer with a thermographic camera. Leaf surface temperature can be used as an indicator of transpiration rate. Using this system, I discovered that parasitically-connected <i>Phtheirospermum japonicum</i> exhibits higher transpiration rates during the daytime compared to non-parasitic individuals. These results suggest that facultative parasitic plants may possess mechanisms to increase transpiration rates when connected to host plants.
