Salt-induced inhibition of primary root elongation in galt3, galt4, and galt6 mutants. Five-day-old WT, galt1, galt3, galt4, and galt6 seedlings germinated on MS medium were transferred onto media containing 100 mM NaCl and grown vertically. Root elongation (i.e., increase in length after transfer) was measured after 7, 14, and 21 days of growth in the non-permissive media. Data are the means ± SE of measurements from five independent experiments (total n = 100). Asterisks indicate mean values significantly different from the WT (Dunnett’s test, *P <0.05; **P <0.01)
