Abstract

While exploring the root cause of trees' gravity sensing, the Morita lab stumbled upon proteins called ‘LAZY’ and dissected their association with the starch-filled packets in roots to dissolve a long-standing dilemma – is gravity sensed in terms of the force that the heavy starch-filled packets exert on the cell content or is it their position that send signals dictating where the Earth is?
