Building synthetic plants

Date: 25.6.2014 

A movement is under way that will fast-forward the design of new plant traits. It takes inspiration from engineering and the software industry, and is being underpinned in Cambridge and Norwich by an initiative called OpenPlant.

Humans have been modifying plants for millennia, domesticating wild species and creating a bewildering array of crops. Modern agriculture allows global cultivation of plants at extremely low cost, with production on the gigatonne scale of a wide range of biostuffs – from fibres, wood, oils and sugar, to fine chemicals, drugs and food.

But, in the 21st century, we face both ever-increasing demand and the need to shift towards more sustainable production systems. Can we build new plants that make better materials, act as miniature 'factories' for food and fuel, and minimise the human impact on the environment?

With this in mind, synthetic biologists are beginning to build new organisms – or at least reprogramme existing organisms – by turning the biology lab into an engineering foundry.

Synthetic biologists choose a 'chassis' and then bolt on standard parts – such as genes, the promoters that activate them and the systems they drive – to build something that's tailor-made. And, like open-source software programmers, they have been looking to open-access and the sharing of code – in this case the DNA that codes for each part – as a practical means of speeding up innovation.

Earlier this year, the University of Cambridge and the John Innes Centre in Norwich received ?12 million in funding for a new UK synthetic biology centre – OpenPlant – to focus on the development of open technologies in plant synthetic biology and their application in engineering new crop traits.

It's one of three new UK centres for synthetic biology that, over the next five years, will receive more than ?40 million in funding from the Biotechnology and Biological Sciences Research Council and the Engineering and Physical Sciences Research Council.
