Abstract
Despite the undisputed importance of xylem in transporting water and solutes around the plant, the negative pressures in this tissue prevents sap collection from transpiring plants. This difficulty has restricted progress in many areas of plant physiology. This project will overcome this barrier by developing and rigorously testing a technique exploiting the xylem feeding insect Philaenus spumaris. We will use a recently developed xylem perfusion system to test the hypothesis that insect excreta composition and xylem sap composition are directly correlated by quantifying the effect of insect metabolism on extracted sap. We will then demonstrate the validity of the technique in in vivo by testing the hypothesis that concentration of xylem solutes are not regulated independently but are a passive consequence of water flux.
