The present invention relates to resveratrol-enriched transgenic rice for biosynthesizing resveratrol at high concentration, in which resveratrol synthase genes are expressibly inserted into the 12.sup.th chromosome of natural rice, and seed of rice produced therefrom. Further, the present invention relates to a health functional food composition, an animal feed composition, and a pharmaceutical composition for preventing and improving a metabolic disease, including seed of rice produced from the resveratrol-enriched transgenic rice for biosynthesizing resveratrol, in which resveratrol synthase genes are expressibly inserted into the 12.sup.th chromosome of natural rice. The seed of rice produced from resveratrol-enriched transgenic rice into which resveratrol synthase genes are inserted, containing high a concentration of resveratrol of the present invention exhibits remarkably superior effects compared to when the same amount of resveratrol is simply ingested. Further, since rice is produced in the form to be used directly as food without an additional process of separating or extracting resveratrol, it may be widely used as food, feed, and medical supplies for preventing and improving a metabolic disease.

The present invention relates, at least in part, to the production of resveratrol from 4-coumaric acid. The production can be mediated in a transgenic Saccharomyces cell.

Provided herein are methods and compositions for producing phenylpropanoid derivatives, such as chalcones and stilbenes, and dihydrophenylpropanoid derivatives, such as dihydrochalcones and dihydrostilbenes, in microorganisms. In particular, the disclosure provides recombinant microorganisms and methods of use thereof for producing phenylpropanoid derivative compounds and dihydrophenylpropanoid derivative compounds.

A biosynthetic method of making pterostilbene including expressing a 4-coumaratexoenzyme A ligase (4CL) in a cellular system, expressing a stilbene synthase (STS) in the cellular system, expressing a resveratrol O-methyltransferase (ROMT) in the cellular system, feeding p-coumaric acid to the cellular system, growing the cellular system in a medium, and producing pterostilbene.

Provided herein are recombinant hosts and methods for producing phenylpropanoid and phenylpropanoid derivative compounds. It was found that tyrosine ammonia lyase from Aeromonas salmonicida A449 provides improved coumaric acid production.

The present invention relates to a recombinant microbial host cell producing a tetraketide or derivatives thereof from one or more substrates selected from cinnamoyl-CoA, p-Coumaroyl-CoA, Caffeoyl-CoA, Feruloyl-CoA, malonyl-CoA, sinapoyl-CoA and dihydro derivatives thereof, comprising an operative biosynthetic metabolic pathway for the tetraketide or derivatives thereof comprising a chalcone isomerase-like (CHIL) polypeptide heterologous to the host cell and a Type 3 polyketide synthase (PKS).

Provided herein are recombinant hosts and methods for producing phenylpropanoid and phenylpropanoid derivative compounds. It was found that tyrosine ammonia lyase from Aeromonas salmonicida A449 provides improved coumaric acid production.

Provided herein are methods and compositions for producing phenylpropanoid derivatives, such as chalcones and stilbenes, and dihydrophenylpropanoid derivatives, such as dihydrochalcones and dihydrostilbenes, in microorganisms. In particular, the disclosure provides recombinant microorganisms and methods of use thereof for producing phenylpropanoid derivative compounds and dihydrophenylpropanoid derivative compounds.
