Phenotypes, total chlorophyll, Na⁺, malondialdehyde (MDA) content and conductivity of silenced plants after 3 days of salt stress. (A) Phenotypes of CaSBP12-silenced and control plants after 3 days of treatment with 400 mM NaCl. The red line is used as a scale bar (length 2 cm). (B) The total chlorophyll content of CaSBP12-silenced and control plants after 3 days of treatment with 400 mM NaCl. (C) The Na⁺, MDA content, and conductivity of CaSBP12-silenced and control plants after 3 days of treatment with 400 mM NaCl. d: days. Bars with different letters indicate significant differences at p ≤ 0.05. Mean values and SDs for three biological replicates are shown.
