Expression of <i>VInv</i> in the bud end and stem end of tubers from <i>VInv</i>-silencing lines of Russet Burbank (RBKx) relative to expression of <i>VInv</i> in untransformed Russet Burbank at harvest and after one, three and five months of storage.

Note: §Asterisks indicate overall differences of least squares means between RBKx and Russet Burbank controls at the same tuber end across sampling times of harvest and one, three and five months of storage. *, p<0.05; **, p<0.01; ***, p<0.001. VInv expression was determined using actin97 as a reference gene and results are presented as a percentage of the level in Russet Burbank controls.
