Global trends in plant transgenic science and technology (1973-2003)

Transgenic science and technology are fundamental to state-of-the-art plant molecular genetics and GM crop improvement. Monitoring the scale and growth of this area of science is important to scientists, national and international research organizations, funding bodies, policy makers and, because of the GM debate, to society as a whole. Literature statistics covering the past 30 years reveal a dramatic increase in plant transgenic science in Asia during the past decade, a sustained expansion in North America and, recently, a slow down in the rest of the world. With the exception of the output of China and India, publications focusing on the development of transgenic technology have been slowing down, worldwide, since the early mid-1990s, a trend that contrasts with the increase in GM croprelated studies.
