Inhibitory effects of ACS2/6 activation and ACC treatment on SDD1 expression and protein accumulation. (A) RT-qPCR-based relative levels of SDD1 mRNA transcripts in immature leaves of WT, acs2-1, acs6-1, acs2-1acs6-1, ACS2-OE(#1), ACS2-OE(#3), ACS6-OE(#1), and ACS6-OE(#3) seedlings. The experiment was repeated three times with consistent results. Values are means ± SD (Student’s t-test; *P < 0.05; **P < 0.01). (B) Evaluation of SDD1 protein levels by western blotting. The fusion protein GFP-SDD1 was collected from immature leaves of pSDD1::SDD1-GFP-expressing WT or acs2-1acs6-1 lines with or without drought treatment. Levels of GFP-SDD1 fusion protein were determined using GFP antibody. GAPDH protein was used as a loading control. The experiment was repeated three times with consistent results.
