Scientists have discovered how cells in the stems of seedlings use blue light to grow towards the light. During earlier research the discovery was made that the cells in the seedling stems responded to blue light used in the microscope. The scientists have now discovered how the blue light causes small structures in the cell, the microtubules, to grow perpendicular to their normal growth direction.
