Fig 3. Abiotic stress responses of the qs-2 mutant.

Fig 3

(A) Phenotype of the qs-2 mutant under exogenous ABA treatment. Five-day-old seedlings of Col-0, qs-2 and two complementation lines grown on 1/2 MS supplemented with 0, 5 or 10 μM ABA for 8 days. (B) The fresh weight of the seedlings shown in (A). Values are the means ± SD of 3 replicates, and each replicate included 9 plants per genotype. The letters a and b above the columns indicate significant difference relative to Col-0 and qs-2 mutant, respectively (P < 0.05, Student’s t-test). (C) Salt sensitivity of the qs-2 mutant. Five-day-old seedlings of Col-0 wild-type, qs-2 and two complementation lines grown on 1/2 MS medium containing 0, 60 or 120 mM NaCl for 8 days. (D) The fresh weight of the seedlings after salt treatment for 8 days. Values are means ± SD (n = 3, each replicate contained 9 plants per genotype). The letters a and b above the columns indicate significant difference relative to Col-0 and qs-2 mutant, respectively (P < 0.05, Student’s t-test). (E) The survival rate of Col-0, qs-2, Com-1, and Com-2 plants shown in (F). Values indicate means ± SD (n = 3 biological replicates, 16 plants per genotype for each replicate). *** P < 0.001, Student’s t-test. (F) Drought resistance assay of Col-0, qs-2, Com-1, and Com-2 plants. Twenty-one-day-old plants were subjected to drought stress for 10 days, and then watered for 3 days for recovery.
