CC   -!- FUNCTION: Probable xyloglucan xylosyltransferase involved in the
CC       biosynthesis of xyloglucan in roots. {ECO:0000250|UniProtKB:Q10MQ0}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Transfers an alpha-D-xylosyl residue from UDP-D-xylose to a
CC         glucose residue in xyloglucan, forming an alpha-(1->6)-D-xylosyl-D-
CC         glucose linkage.; EC=2.4.2.39; Evidence={ECO:0000305};
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000305}; Single-
CC       pass type II membrane protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 34 family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=EAY89653.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
