	Root Length
	Salt Cress Wild Type	Salt Cress let1
	mm
NaCl Concentration (mm)
0	18.20 ± 1.200	16.50 ± 1.10
250	8.63 ± 0.459	6.10 ± 0.77a
300	6.99 ± 0.626	4.98 ± 0.69b
KCl Concentration (mm)
0	18.20 ± 1.20	16.50 ± 1.10
250	1.33 ± 0.36	1.12 ± 0.32
300	1.95 ± 0.29	1.29 ± 0.21a

Six-day-old seedlings were transferred to agar plates containing MS medium or MS medium supplemented with NaCl or KCl. Root elongation occurring within the 10-d period after transfer is presented. Values are means ± se; n = 15.

^aSignificantly different from salt cress wild type (P < 0.05; Student's t test).

^bSignificantly different from salt cress wild type (P < 0.01; Student's t test).
