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

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