New Tool Offers Unprecedented Access for Root Studies

Stanford, CA — 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. The findings will be published in the large-scale biology section of the December issue of The Plant Cell. (more…)

Scientists Watch Cell-Shape Process for First Time

Palo Alto, CA — Researchers at the Carnegie Institution for Science, with colleagues at the Nara Institute of Science and Technology, observed for the first time a fundamental process of cellular organization in living plant cells: the birth of microtubules by studying recruitment and activity of individual protein complexes that create the cellular protein network known as the microtubule cytoskeleton—the scaffolding that provides structure and ultimately form and shape to the cell. These fundamental results could be important to agricultural research and are published in the October 10, 2010, early on-line edition of Nature Cell Biology. (more…)
