Biotechnology

Biotechnology is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity, Art. 2). Depending on the tools and applications, it often overlaps with the (related) fields of bioengineering and biomedical engineering.

For thousands of years, humankind has used biotechnology in agriculture, food production, and medicine. The term itself is largely believed to have been coined in 1919 by Hungarian engineer Károly Ereky. In the late 20th and early 21st century, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene technologies, applied immunology, and development of pharmaceutical therapies and diagnostic tests.

Carnations do not naturally produce the pigment delphinidin,thus a blue carnation cannot occur by natural selection or be created by traditional plant breeding.
Around 1996 a company (Florigene) used genetic manipulation to extract certain genes from petunia and snapdragon flowers to produce a blue-mauve carnation, which was commercialized as Moondust.
In 1998 a violet carnation called Moonshadow was commercialized. As of 2004 three additional blue-violet/purple varieties have been commercialized.
