Decreased salinity tolerance of RcMYB8-silenced rose plants. A Relative expression of RcMYB8 in TRV and TRV-RcMYB8. RcUBI2 was used as an internal control of three biological replicates. B Performance of TRV and TRV-RcMYB8 in rose seedlings under normal and salinity stress conditions. Nine-week-old rose plants were subjected to 0 and 200 mM NaCl for 3 days. Scale bar: 1 cm. C to F Ca2+ content (C), K+ content (D), Na+ content (E), and Na+/K+ ratio (F) in TRV and TRV-RcMYB8 plants after 200 mM NaCl treatment. Data are the mean ± SD (n = 3)
