Professor Kentaro Shimizu (45), of the University of Zurich in Switzerland, is trying to uncover the secrets to plant diversity by decoding plant genes while conducting field work in the Swiss Alps. Most organisms including animals have only about 20,000 to 30,000 genes, and Shimizu is hoping to understand why there are so many different species of organisms living on the earth. Through his research, he's learned that the numbers of chromosomes inherited from parents play a significant role in the evolution and diversification of living organisms. Shimizu is also applying his research findings to creating an improved wheat variety that will survive the changing global environment. We'll follow Professor Shimizu as he explores the mystery of plant diversity.
