The qRT-PCR-assisted transcriptional characterization of the amino acid permease (AAP) genes in Brassica napus under cadmium (Cd) toxicity. Differential expression of the BnaAAP1 (a), BnaAAP2 (b), BnaAAP3 (c), BnaAAP4 (d), BnaAAP5 (e), BnaAAP6 (f), BnaAAP7 (g) and BnaAAP8 (h) genes under NaCl-free (−NaCl) and salt (+NaCl, 200 mM NaCl) treatments. For the transcriptional analysis, the 7-d-old uniform B. napus seedlings after seed germination were hydroponically cultivated in a NaCl-free solution for 10 d, and then were transferred to 200 mM NaCl for 12 h. The shoots and roots were individually sampled, and each sample includes three independent biological replicates. The significance level of P < 0.05 is used as the threshold to identify the differential BnaAAP expression under cadmium-free and cadmium treatments. The differentially expressed genes with higher expression between different treatments in the shoots or roots are indicated with asterisks
