AtPPRT1 affects the elongation of hypocotyl in etiolated seedlings under salt stress. (a) Col-0, atpprt1, OE2, and OE10 were grown for 2 days on 1/2 MS medium plates and then transferred to 1/2 MS supplemented with 120 mM NaCl and grown for 5 days. All the seedlings were grown in the dark; (b) the hypocotyl lengths of samples used in (a) were measured. These experiments were repeated three times with similar results. Error bars represent ± SD (n = 21, * p < .05 and ** p < .01, t-test); (c) qRT-PCR analysis of the transcriptional expression levels of AtMAP18 and AtBSK1 in Col-0, atpprt1, OE2, and OE10 in 120 mM NaCl. These experiments were repeated three times with similar results. Error bars represent ± SD (n = 3, *p < .05, **p < .01, t-test).
