Phenotypic analysis of OsOTS-RNAi and OsOTS1-overexpressing lines under salt stress. Images of 10-d-old rice seedlings of various genotype in MS medium without salt (−NaCl; A) and MS medium with 150 mm NaCl (+NaCl; B). Shoot length (C) and shoot fresh weight (D) of 10-d-old plants grown in liquid MS medium (with or without 150 mm NaCl). Each column represents an average of three individual biological replicates with 20 seedlings in each experiment. Error bars indicate sd. P values for differences between empty vector only and the transgenic lines: *P < 0.05 and ***P < 0.0001 (two-way ANOVA test).
