Growth retardation of the Oshak8 mutants under K+-deficient conditions. (A) Growth retardation of the Oshak8 mutants under K+-deficient conditions. The seeds of the wild-type plants (WT) and Oshak8 mutants (Oshak8-1, Oshak8-2) germinated in water for 5 days, grown in hydroponic solutions containing 0, 1, or 10 mM of K+, and then photographed after 14 days. Oshak8 mutants (Oshak8-1, Oshak8-2) displayed growth retardation under the K+-deficient conditions. Bars = 4 cm. (B) Plant height of WT and Oshak8 mutants under various K+ concentrations. Root lengths of 14-day-old seedlings were measured. Growth conditions were as described in (A). (C) Root lengths of WT and Oshak8 mutants. Growth conditions were as described in (A). (D) Fresh weight of WT and Oshak8 mutants. Growth conditions were as described in (A). (E) Chlorophyll contents of WT and Oshak8 mutants. Growth conditions were as described in (A). Significant differences were found between WT and Oshak8 knockout plants (Oshak8-1, Oshak8-2) (*P < 0.01 by Student’s t-test). Data are means of three replicates of one experiment. The experiment was repeated three times with similar results. Error bars represent ± SD. Asterisks represent significant differences.
