1 tomato = 50 bottles of wine: Scientists produce Resveratrol in tomatoes

27 October 2015  •  Author(s): Victoria White

Scientists at the John Innes Centre have found a way to produce industrial quantities of useful natural compounds by growing them in tomatoes.


The compounds are phenylpropanoids like Resveratrol, the compound found in wine which has been reported to extend lifespan in animal studies, and Genistein, the compound found in soybean which has been suggested to play a role in prevention of steroid-hormone related cancers such as breast cancer. 

As a result of the research led by Dr Yang Zhang and Dr Eugenio Butelli, one tomato can produce the same quantity of Resveratrol as exists in 50 bottles of red wine. One tomato has also produced the amount of Genistein found in 2.5kg of tofu.

The scientists have been studying the effect of a protein called AtMYB12 which is found in Arabidopsis thaliana. The protein AtMYB12 activates a broad set of genes involved in metabolic pathways responsible for producing natural compounds of use to the plant. The protein acts a bit like a tap to increase or reduce the production of natural compounds depending on how much of the protein is present. 

What was interesting about the effect of introducing this protein into a tomato plant was how it acted to both increase the capacity of the plant to produce natural compounds and to influence the amount of energy and carbon the plant dedicated to producing these natural compounds. In response to the influence of the AtMYB12 protein, tomato plants began to create more phenylpropanoids and flavanoids and to devote more energy to doing this in fruit.

Tomatoes could be used for industrial scale production of Resveratrol

Introducing both AtMYB12 and genes from plants encoding enzymes specific for making Resveratrol in grape and Genistein in legumes, resulted in tomatoes that could produce as much as 80mg of novel compound per gram of dry weight –demonstrating that industrial scale up is possible. 

Tomatoes are a high yielding crop. Production of valuable compounds like Resveratrol or Genistein in tomatoes could be a more economical way of producing them than relying on artificial synthesis in a lab or extracting them in tiny quantities from traditional plant sources. The tomatoes can be harvested and juiced and the valuable compounds can be extracted from the juice. The tomatoes themselves could potentially become the source of increased nutritional or medicinal benefit. 

Professor Cathie Martin said, “Our study provides a general tool for producing valuable phenylpropanoid compounds on an industrial scale in plants, and potentially production of other products derived from aromatic amino acids. Our work will be of interest to different research areas including fundamental research on plants, plant/microbe engineering, medicinal plant natural products, as well as diet and health research.”

Dr Yang Zhang, said, “Medicinal plants with high value are often difficult to grow and manage, and need very long cultivation times to produce the desired compounds. Our research provides a fantastic platform to quickly produce these valuable medicinal compounds in tomatoes. Target compounds could be purified directly from tomato juice. We believe our design idea could also be applied to other compounds such as terpenoids and alkaloids, which are the major groups of medicinal compounds from plants.”

    I take Resveratrol every day. This is so healthy and helps battle almost any disease you can think of and helps you to live longer.
