The prt6 mutation induced mRNA accumulation of genes associated with salinity tolerance. (A) Relative mRNA levels of transcription factors involved in ABA-dependent (AREB/ABFs) and independent (DREB2s) pathways of salinity/osmotic stress tolerance and their downstream genes, dehydrins. (B) Relative mRNA levels of sodium transporter genes. Ten-day-old seedlings were treated with 150 mM NaCl for up to 3 d and subjected to qRT-PCR analysis. Data represent means ± SE (n = 3). Asterisks indicate significant difference between WT and prt6 (* p < 0.05; ** p < 0.01, *** p < 0.001).
