In wounded sugar beet (Beta vulgaris l.) tap-root, hexose accumulation correlates with the induction of a vacuolar invertase isoform

Abstract

Wounding of sugar beet tap-root causes an induction of invertase activity, which contributes to postharvest sucrose losses. In this first comprehensive monitoring of wound-induced invertase mRNAs, proteins, enzyme activities, and tissue hexose concentrations, the VI isoform responsible for woundinduced hexose accummulation in mature tap-root could be identified.
