Genetically Modified Crops

Plant molecular biology came to the fore in the early 1980s and there has been tremendous growth in the subject since then. The study of plant genes and genomes and the development of techniques for the incorporation of novel or modified genes into plants eventually led to the commercialization of genetically modified (GM) crops in the mid-1990s. This was seen as the start of a biotechnological revolution in plant breeding. However, plant biotechnology has become one of the hottest debates of the age and, in Europe at least, one of the greatest challenges that plant scientists have ever faced. This is a description of the history and development of the science and techniques that underpin plant biotechnology, GM crops that are grown commercially around the world and the new varieties that are being developed. It covers failures as well as successes. The safety record of GM crops is reviewed together with the legislation that has been adopted to cover their use. The author also deals with the concerns of consumers, the GM crop debate and the prospects for the technology.
