Sucrose Hydrolysis in Relation to Phloem Translocation in Beta vulgaris1

PMCID: PMC542612  PMID: 16660089

Abstract

Asymmetrically labeled sucrose, 14C(fructosyl)sucrose, was used to determine whether sucrose undergoes extracellular hydrolysis during phloem translocation in the sugar beet, Beta vulgaris. In addition, the metabolism of various sugars accumulated and translocated was determined in various regious of the plant. These processes were studied in detached regions as well as in the intact, translocating plant in the source leaf, along the translocation path, and in a rapidly growing sink leaf and storage beet. The data show that, unlike sucrose accumulation into the sink tissue of sugarcane, sucrose is neither hydrolzyed prior to phloem loading or during transit, nor is it extracellularly hydrolyzed during accumulation into sink leaves or the storage beet.
