Team Biofuels with Ingo Potrykus.

Ingo Potrykus was full Professor of Plant Sciences, specifically of Biotechnology of Plants, at the Institute of Plant Sciences of the ETH Zurich from June 1, 1987 until his retirement on April 1, 1999. His research group applied gene-technology to contribute to food security in developing countries. Together with Peter Beyer, he is one of the co-inventors of golden rice and currently serves as chairman of the Golden Rice Humanitarian Board.[1]

Background

Potrykus was born on December 5, 1933 in Hirschberg im Riesengebirge, Germany. He studied biology at the University of Cologne and earned his doctorate with a thesis at the Max-Planck Institute for Plant Breeding Research. After several years at the Institute of Plant Physiology, University of Hohenheim, he became research group leader at the Max-Planck Institute for Plant Genetics. In 1976 he transferred to Basel, Switzerland to establish the area of plant genetic engineering at the Friedrich Miescher Institute.[1]

Research

Motivated by the upcoming food crisis problem of malnutrition in developing countries and the potential of gene technology to contribute to food security, Potrykus and his research group dedicated their work to genetic engineering projects aimed at improving yield stability and food quality of rice, wheat, millets and manioc crops.[2] The most significant development so far has been the creation of golden rice, a new rice variety providing provitamin A. This strain of rice is widely seen as the model example of how to sustainably reduce malnutrition in developing countries. Potrykus began thinking about using genetic engineering to improve the nutritional qualities of rice in the late 1980s. He knew that of some 3 billion people who depend on rice as their staple crop, around 10% risk some level of vitamin-A deficiency. This problem interested Potrykus for numerous reasons, including the scientific challenge of transferring not just a single gene, but a group of genes that represented a key part of a biochemical pathway. In 1993, with funding from the Rockefeller Foundation, Potrykus teamed up with Peter Beyer and they launched what would become a 7 year, $2.6 million project to develop Golden Rice.[3]

Since his retirement, Ingo Potrykus - as president of the International Humanitarian Golden Rice Board - is devoting his energy to guiding Golden Rice towards subsistence farmers across the many hurdles of a GMO-crop. To this end collaboration he has been established with 14 rice institutions in India, China, Vietnam, Bangladesh, Indonesia, and Philippines.
