abstract = {The sugar alcohol sorbitol is a major translocatory product
in most commercially important species in the Rosaceae
family. Sugar alcohols are thought to play a variety of
roles in plant tissue, including protecting metabolism
during stress. Sorbitol has been found in high
concentrations in 1-year-old apple (Malus domestica) shoots,
however studies have shown that not all tissue throughout a
tree has the ability to metabolise sorbitol. In this study,
we looked at sorbitol metabolism in 1-year-old apple shoots
using a variety of methods including carbohydrate depletion,
metabolism of C-14-sorbitol, and extraction of sorbitol
dehydrogenase (SDH), the enzyme necessary to convert
sorbitol to fructose. Although starch stores were able to be
depleted in the shoot, sorbitol levels increased,
corresponding to the decrease in starch, resulting in little
net loss of carbohydrate. 14C-sorbitol was not metabolised
and no SDH was found in shoot tissue, suggesting that
sorbitol has limited metabolism in 1-year-old apple shoots.
Sorbitol may thus be ideal for translocation in apple shoot
tissue because of its ready movement into the transport
pathway, but its restricted utilisation there.},
