GmSULTR1;2b-overexpressing tobacco plants grown under 200 mM mannitol treatment. (a) Phenotypes of GmSULTR1;2b-overexpressing tobacco seedlings grown under 200 mM mannitol treatment for 4 weeks. (b) Fresh weight of GmSULTR1;2b-overexpressing tobacco seedlings grown under 200 mM mannitol treatment. (c) Root length of GmSULTR1;2b-overexpressing tobacco seedlings grown under 200 mM mannitol treatment. (d) Number of lateral roots of GmSULTR1;2b-overexpressing tobacco seedlings grown under 200 mM mannitol treatment. Ten biological replicates were performed. Error bars represent the standard deviation. Asterisks (*) indicate significant differences at P < 0.05 (Student’s t-test), and double asterisks (**) indicate significant differences at P < 0.01 (Student’s t-test). CK, tobacco plant transformed with the pMDC83 empty vector as a control; S22, S26 and S29, tobacco plants transformed with GmSULTR1;2b. Scale bar = 1 cm
