Method for using hexenol glycosyl transferase

A method for producing a hexenol glycoside, comprising:

• providing a cell comprising a polynucleotide encoding a protein, wherein said cell expresses said protein, and said cell is a microorganism or a transgenic plant cell, and
• contacting within or outside of the cell said protein with a UDP-sugar and a hexenol molecule to cause glycosylation of the hexenol molecule and to thereby produce a hexenol glycoside,
• wherein said polynucleotide comprises a nucleotide sequence encoding said protein and an expression control region that controls expression of said nucleotide sequence and wherein the nucleotide sequence encoding said protein and/or the expression control region is heterologous to said cell,
• wherein said protein has glycosylation activity on the hexenol molecule and is selected from the group consisting of:
• (a) a protein consisting of the amino acid sequence of SEQ ID NO:
• 2 or 4;
• (b) a protein consisting of the amino acid sequence of SEQ ID NO:
• 2 or 4, except that no more than 1 to 24 amino acids are deleted, substituted, inserted, and/or added;
• and
• (c) a protein comprising an amino acid sequence that has 95% or more sequence identity with the amino acid sequence of SEQ ID NO:
• 2 or 4.
