Fig 5. Germination rates of TaCRT1-overexpressing tobacco plants and WT plants under salt stress and activities of antioxidant enzymes in the roots of transgenic and non-transgenic tobacco.

(A) Germination at 25°C ambient temperature of seeds sown on filter papers saturated with water or with 150 mM NaCl. Photographs were taken 6 d after sowing. (B) Germination rate from day 0 to day 6 after sowing. WT represents non-transgenic tobacco; T6 and T10 represent transgenic tobacco lines. Error bars represent the standard deviation of results obtained for three replicate experiments. (C) Activities of antioxidant enzymes SOD, POD and CAT in the roots from potted WT and transgenic (T6) tobacco under normal growth conditions.
