FLA4‐citrin supports normal root growth and salt tolerance in the sos5‐1 and sos5‐2 mutant background.
(a) Phenotype of 6‐day‐old seedlings growing on standard medium without (MS0) or with 100 mm NaCl (2 dpi)
(b) Root length and thickness on MS0 for 5–6 days and root width and elongation growth for 2 days on 100 mm NaCl containing medium. The F4C transgene driven by the FLA4 or the UBQ10 promoter expressed in sos5‐1 (Col gl) and the sos5‐2 (Col‐0/Col gl) mutant background show a wild‐type like growth phenotype. The transgenic lines (yellow bars) used for this figure were 1: FLA4:F4C(4) (sos5‐1), 2: FLA4:F4C(7) (sos5‐1), 3: UBQ10:F4C(5) (sos5‐1), 4: UBQ10:F4C(6) (sos5‐1), 5: FLA4:F4C(4) (sos5‐2), 6: FLA4:F4C(7) (sos5‐2), 7:UBQ10:F4C(3) (sos5‐2), 8:UBQ10:F4C(4) (sos5‐2). Error bars indicate the 5% confidence interval.
