(A–F) Growth parameters of the proximal meristem and transition zone in Arabidopsis primary roots, ± salt treatments. (A) Root length after varying periods of treatment with NaCl (50–150 mM). (B) Intact 3-day-old control root tip. (C) Intact tip from root treated 3 days with 100 mM NaCl. Note the shortening of the PM in the salt-treated root (scale bar = 20 μm). (D–F) Comparison of cellular characteristics of the PM and TZ in roots treated with 100 mM salt for 3 days: D, overall lengths; E, number of cells; F, cell length. PM, proximal meristem, TZ, transition zone, n = 6; *indicates a statistical significance of p < 0.05.
