Plant roots are fascinating plant organs – they not only anchor the plant, but are also the world’s most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant’s brain. Due to the difficulty of accessing root tissue in intact live plants, research of these hidden parts has always lagged behind research on the more visible parts of plants. But now: a new technology--developed jointly by Carnegie and Stanford University--could revolutionize root research.
