pat10 Mutants Are Hypersensitive to Salt Stresses.
(A) Seedlings growing either on MS medium, on MS medium supplemented with 10 mM LiCl, or on MS medium supplemented with 130 mM NaCl. Col-0, Columbia-0.
(B) and (C) Fresh weight (B) and rosette diameter (C) of seedlings (aerial parts only) grown on either MS medium, MS medium supplemented with 10 mM LiCl, or MS medium supplemented with 130 mM NaCl. All seedlings were grown on MS for 4 d before being transferred to MS medium or MS supplemented with salts for an additional 14 d. Data were collected from three independent experiments in which at least 30 seedlings were included in each experiment. Results are given as means ± se. Asterisks indicate significant differences (Student’s t test, P < 0.01).
(D) Induction of salt responsive genes RD29A, RD20, ERD10, and RAB18 in the wild type or pat10. Asterisks indicate significant differences (Student’s t test, P < 0.01).
