Quantitative reverse transcription‐polymerase chain reaction (qRT‐PCR) analysis of GmSIZ1a and GmSIZ1b expression level in response to salicylic acid (SA), heat, drought, cold, abscisic acid (ABA) and NaCl treatments Fourteen‐day‐old soybean seedlings were treated with 2 mM SA (A), 45 °C heat stress (B), drought (C), 4 °C cold stress (D), 200 μM ABA (E), and 250 mM NaCl (F) for the indicated periods. GmPR1, GmDREB2, and GmHSF12 were used as stress‐ or hormone‐responsive positive controls. Relative expression was normalized to that of GmUBI3, and data represent the mean ± SD, n = 3.
