Root elongation reached 20 mm day−1 in certain roots. No significant differences were found in elongation between day and night over an interval of 10 days measured using a time-lapse camera. The red color represents root elongation during the day (data above the 0 on y axis) and the blue color represents root elongation during the night (data below the 0 on y axis). If no bars are present, roots did not grow during that period (even though they were still alive). The date above the first data point indicates when root growth started
