Revolution Bioengineering
Revolution Bioengineering is a biotech company in Fort Collins, Colorado, United States that is working to create a plant that changes color throughout the day on its own using synthetic biology techniques to harness genes involved in the color and internal clock systems in petunias.〔Yaakoba-Zohar Noa (November 26, 2014). ("Beautiful Biotechnology: Color-Changing Flowers" ). GetSynBio.〕 The company started as part of the inaugural class of Ireland-based SynBio Axlr8r, a three month business accelerator program awarding $60,000 and mentoring to biotech start-ups using synthetic biology.〔Colm Gorey (May 26, 2014). (“An idea blossoming: Revolution Bioengineering” ). The Silicon Republic.〕 One of the company's goals is to embrace the current GMO controversy and work to show capabilities of synthetic biology through their project.〔Koebler Jason (September 18, 2014). ("Will People Actually Buy Color Changing, Biohacked Flowers?" ). Motherboard.〕

To create the plants the project will utilize the existing anthocyanins in petunia. Anthocyanins color many flowers and fruits. They absorb light in the visible spectrum and may appear red, purple or blue depending on the pH, the presence or absence of metal ions, and other molecular interactions.〔Andersen, Øyvind M.; Jordheim, Monica (2008). "Anthocyanins- food applications". 5th Pigments in Food congress- for quality and health. University of Helsinki.ISBN 978-952-10-4846-3〕
The color of the anthocyanins will be controlled using circadian rhythms, an internal clock system found in many organisms that works to control gene expression over time.〔Webb AAR (June 2003). "The physiology of circadian rhythms in plants". New Phytologist 160 (160): 281–303.doi:10.1046/j.1469-8137.2003.00895.x.JSTOR 1514280.〕 Using the principles of synthetic biology, the company will control the expression of a gene that modifies pH.〔 Mukherji Shankar. (December 2009). "Synthetic biology: understanding biological design from synthetic circuits". Nature Reviews Genetics 10, 859-871. doi:10.1038/nrg2697.〕 Connecting these systems genetically can potentially create plants that change color throughout the day.〔(May 23, 2014).
