Expression levels of StNAC262 gene under 20% PEG6000 stress treatment. Relative expressional levels of StNAC262 in response to osmotic stress treatment for 0, 4, 8, 16, and 32 h. (A) qRT-PCR analysis of potato “Gannongshu 2.” CK1: non-transgenic potato “Gannongshu 2” as negative control; T1–T2: the transgenic potato plant transformed with the vector pCPB121-miR164. (B) qRT-PCR analysis of potato “Kexin 3.” CK2: non-transgenic potato “Kexin 3” as negative control; T3–T4: the transgenic potato plant transformed with the vector pCPB-NAC262. Data presented as a mean ± SD (three biological replicates), different letters above the columns indicate significant differences at p ≤ 0.05 levels with corresponding CK.
