A phloem- sap feeder mixes phloem and xylem sap to regulate osmotic potential. J. Insect Physiol. 57, 1317-1322.Pompon J, Quiring D, Goyer C, Giordanengo P, Pelletier Y (2011) A phloem-sap feeder mixes phloem and xylem sap to regulate osmotic potential. J Insect Physiol 57:1317-...
Phloem-sap feeders (Hemiptera) occasionally consume the dilute sap of xylem, a behaviour that has previously been associated with replenishing water balance following dehydration. However, a recent study reported that non-dehydrated aphids ingested xylem sap. Here, we tested the hypothesis that the co...

Unlike the xylem, which is composed primarily of dead cells, thephloemconsists of live cells that transport sap both up and down through the plant body. The sap is a water-based solution but rich in sugars synthesized by the photosynthetic regions. The sugars are transported to non-photosynthet...
