Task: Answer Verification
Input (English): Question: Do pollen tube cell walls of wild and domesticated tomatoes contain arabinosylated and fucosylated xyloglucan?
Answer: The results clearly indicate that the male gametophyte (pollen tube) and the sporophyte have structurally different XyG. This suggests that fucosylated XyG may have an important role in the tip growth of pollen tubes, and that they must have a specific set of functional XyG fucosyltransferases, which are yet to be characterized.
Output (English): yes
