Production of citronellal and citronellol in recombinant hosts

A recombinant host cell capable of producing a citronellal and/or a citronellol, comprising:

• (a) a gene encoding a geranyl diphosphate synthase (Ag_GPPS) polypeptide comprising a polypeptide having the amino acid sequence set forth in SEQ ID NO:
• 17;
• (b) a gene encoding a geraniol synthase (Cr_GES) polypeptide comprising a polypeptide having the amino acid sequence set forth in SEQ ID NO:
• 18;
• (c) a gene encoding an ene reductase (KI_KYE1) polypeptide comprising a polypeptide having the amino acid sequence set forth in SEQ ID NO:
• 7;
• and
• (d) a gene encoding a geraniol dehydrogenase (Rs_GeDH) polypeptide comprising a polypeptide having the amino acid sequence set forth in SEQ ID NO:
• 2 or SEQ ID NO:
• 20,
• wherein the recombinant host cell is an Escherichia coli cell.
