Excised 20-d-old sunflower roots (Helianthus annuus L. cv. Sun-Gro 393) were used to study the effect of different sugars on rubidium and water fluxes. The roots sensed and absorbed glucose from the external medium inducing the activation of rubidium accumulated in the root (Rb(+) root), the flux of exuded rubidium (J(Rb)) and, to a lesser degree, the exudation rate (J(v)). These effects were also triggered by fructose, but not by 6-deoxyglucose (6-dG), a glucose analogue which is not a… CONTINUE READING
