Comparison of root biomasses of DT2008 and W82 plants under drought stress. Five-day-old DT2008 and W82 plants grown in pots were exposed to 15 or 20 days of water withholding. (a) Comparison of dry weights of root biomasses of DT2008 and W82 plants after 15 days of drought stress. (b) Representative root samples of DT2008 and W82 plants grown under well-watered control or drought stress (15 days of stress) conditions. (c) Comparison of dry weights of root biomasses of DT2008 and W82 plants after 20 days of drought stress. (d) Representative root samples of DT2008 and W82 plants grown under well-watered control or drought stress (20 days of stress) conditions. Error bars represent standard errors (n = 10 plants/genotype). Asterisks indicate significant differences as determined by a Student's t test (*P < 0.05).
