- •
Both UGE transgenes were expected to modify cell wall galactose levels.
- •
UGE 45-1 transgenic potato had elongated pectin galactan side chains.
- •
Part of the pectin populations from UGE 51-16 potato had short side chains.
- •
Pectin of UGE transgenic lines had low acetylation and high methyl-esterification.
- •
Ratio of xyloglucan building blocks differed for UGE transgenic lines and wild-type.
