Methods for producing anthocyanin by expression in a microorganism are disclosed including culturing of the microorganism under anthocyanin producing conditions, wherein the microorganism has an operative metabolic pathway including at least one heterologous enzyme activity, the pathway producing anthocyanin from simple sugars or other simple carbon sources.

The invention is directed to methods involved in the production of flavonoids, anthocyanins and other organic compounds. The invention provides cells engineered for the production of flavonoids, anthocyanins and other organic compounds, where the engineered cells include one or more genetic modifications that increase flavonoid production by increasing metabolic flux to flavonoid precursors and/or reducing carbon losses resulting from the production of byproducts.

Disclosed herein are novel microbial polycultures of two or more cell strains, capable of producinges, flavonoids, and anthocyanidin-3-O-glucosides, and methods of use thereof. Also disclosed is a microbial cell capable of producing phenylpropanoic acids, and methods of use thereof.

Disclosed herein are novel microbial polycultures of two or more cell strains, capable of producing flavanones, flavonoids, and anthocyanidin-3-O-glucosides, and methods of use thereof. Also disclosed is a microbial cell capable of producing phenylpropanoic acids, and methods of use thereof.

Provided are transgenic organisms, such as plants and plant parts, cells, and related compositions and methods for producing and monitoring the genotype for enhanced production of montbretin A and/or its precursors. For example, provided is a transgenic organism comprising at least one heterologous nucleic acid operatively linked to a promoter, wherein the heterologous nucleic acid encodes at least one enzyme in a montbretin A (MbA) metabolic pathway. The organisms can be a plant, plant part, or plant cell, or a microorganism such as a yeast. Also provided is a method for producing at least one montbretin A (MbA) precursor and/or MbA, comprising permitting the expression of the at least one heterologous nucleic acid in the transgenic organism. The disclosure also provides isolated nucleic acid molecules that comprise sequence encoding at least one enzyme in a montbretin A (MbA) metabolic pathway and vectors comprising the nucleic acids.
