Clean-gene technology has promise for safe genetically-modified crops. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Summary for Project titles: R7548: Development of clean gene technology for rice transformation, and mapping of natural resistance to rice yellow mottle virus and nematodes in rice interspecific crosses and R8031: Genetic transformation of rice, potato and cooking bananas for nematode resistance.

An easy and efficient way to develop genetically-modified crops that are 'biosafe' is now available. People worldwide are reluctant to accept genetically-modified foods. They are afraid that they might contain genes, such as those resistant to antibiotics or herbicides, which could be harmful. The clean-gene technology has great potential for Asian and African research programmes that aim to improve rice by genetic methods. It can also be readily used to improve crops grown by poor farmers in China, India and South Africa. Not only important staples, such as maize and wheat, but also orphan crops, such as millet, cowpea, sorghum and many fruits, nuts and vegetables could be improved by this technology. Laboratories in Asia, Africa, the USA and the UK are already using this process.
