The capacity for 1-kestose uptake into the vacuole of fructan storing Jerusalem artichoke tubers was investigated. 1-kestose serves both as building block for fructan initiation and as a fructose donor for chain elongation. Tonoplast vesicles were isolated from actively storing tubers, and their vesicles were capable of transporting sucrose in a manner indicative of a sucrose/H(+) antiport. Under similar conditions, 1-kestose was not taken up by vesicles energized by either a pH jump or in the presence of ATP. When added together at 2 mM, sucrose uptake was not affected by the presence of 1-kestose. The data argues against the possible synthesis of 1-kestose in the cytosol and subsequent transport to the vacuole. The data also presents definite evidence for the existence a mechanism for sucrose accumulation in fructan storing vacuoles.
