Bee-less honey

A kit comprising:

• i. a first expression vector polynucleotide comprising at least one first promoter operatively linked to a first open reading frame, wherein said first open reading frame encodes a signal peptide and an invertase enzyme, wherein said invertase enzyme is encoded by a sequence comprising SEQ ID NO:
• 4 or SEQ ID NO:
• 5 or a sequence homologous thereto that converts one molecule of sucrose into one molecule of glucose and one molecule of fructose;
• and
• ii. a second expression vector polynucleotide comprising a repressible promoter operatively linked to a second open reading frame, wherein said second open reading frame encodes a signal peptide and a glucose oxidase enzyme, wherein said glucose oxidase enzyme is encoded by a sequence comprising SEQ ID NO:
• 6 or 7 or a sequence homologous thereto that converts one glucose molecule into one molecule of glucono-1,5-lactone and one molecule of hydrogen peroxide, and wherein said repressible regulatory element inhibits transcription of said second open reading frame in response to hydrogen peroxide.
