Phenotypes of transgenic Arabidopsis plants overexpressing bolTLP1 under drought stress. (A,B): Phenotypes of 35S::bolTLP1 Arabidopsis at 0 day and 15 days after the water deficit. (C): Phenotypes of 35S::bolTLP1 Arabidopsis at 5 days after rewatering. (D,E): Phenotypes of 14-day-old 35S::bolTLP1 Arabidopsis seedlings growing in 1/2 MS medium with 200 mM and 300 mM mannitol, respectively. (F): Primary root length of 35S::bolTLP1 transgenic Arabidopsis at 14 days after growing in 1/2 MS medium with 200 mM and 300 mM mannitol. (G): Survival rate of 35S::bolTLP1 Arabidopsis at 5 days after rewatering. (Student’s t-test, ** p < 0.01; data are means ± SD (n ≥ 20).) The top row of A, B and C showed the vector controls (CK), and the middle and bottom rows showed the independent 35S::bolTLP1 Arabidopsis lines (L2, L5 and L8).
