    Western blot using anti-GNSOR antibody
    2 µg of total protein from (1) Arabidopsis thaliana WT and GSNOR null mutant were separated on 7.5%SDS-PAGE and blotted 1h to nitrocellulose (Biorad). Blots were incubatedanti-GSNOR antibodies at a dilution of 1: 1 000 for 1h at room temperature with agitation and secondary HRP-conjugated antibody (1: 10 000).

    AtCaM4 binds to GSNOR in response to salt stress.(A) In planta BiFC assay of the CaM4 interaction with GSNOR in tobacco leaves. The C-terminal half of YFP was fused to CAM4 (CaM4-YC) and GSNOR (GSNOR-YC), and the N-terminal half of YFP was fused to GSNOR (GSNOR-YN) and CAM4 (CaM4-YN). The expression of CaM4-YC/YN and CaM4-YN/YC was used as a control. Bar = 50 ?m. (B) Model of the GSNOR N- and C-terminal deletions for the overlay assay. (C) In vitro overlay assay of the CaM4 interaction with GSNOR. GST and GST-GSNOR fusion proteins were expressed in E. coli. Recombinant proteins were analyzed by Western blotting (WB) using anti-GST antibodies. The overlay assay was performed using CaM4-His in the presence of 0.1 mM CaCl2 or 0.1 mM EGTA. (D) Co-IP assays showing the interaction between CaM4 and GSNOR. CaM4-GFP was expressed from the native CaM4 promoter. Extracted proteins were incubated with anti-GFP agarose beads. Total and immunoprecipitated proteins were analyzed by immunoblotting using anti-GSNOR and -GFP antibodies.
