Root growth in response to salt, osmotic, and ABA treatment in HSFA6s mutants. A and B, Three-day-old seedlings grown on half-strength Murashige and Skoog medium were transferred to plates containing NaCl, mannitol, or ABA, as indicated. Root length (cm) and relative root elongation (%) were measured at day 9. C, Seeds were planted in half-strength Murashige and Skoog medium (control), and medium containing 100 mm NaCl or 150 mm mannitol, and then photographed at day 9. Data are means ± sd of three biological replicates. *Significant at P < 0.05 compared with the Col.
