Immunoblot analysis of reaction center proteins of PSI (PsaA, a) and PSII (PsbA, b) in the leaves of Glycine max (GM) and Glycine soja (GS) after 9 days of salt stress with 300 mM NaCl. Total performance index (PItotal, c), PSII performance index (PIabs, d), the maximal photochemical efficiency of PSII (Fv/Fm, e) and PSI (△MR/MR0, f), primary quinone reducing reaction centers per PSII antenna chlorophyll (RC/ABS, g), variable fluorescence intensity at K step (Vk, h), probability that an electron moves beyond primary quinone (ETo/TRo, i) and probability with which an electron from the intersystem electron carriers is transferred to reduce end electron acceptors at the PSI acceptor side (REo/ETo, j) in the leaves of Glycine max (circles) and Glycine soja (triangles) exposed to 0 (closed symbols) and 300 mM (open symbols) NaCl. Data in the figure indicate the mean of five replicates (±SD). Different letters indicate significant difference among GS, GM, GS + NaCl and GM + NaCl at P < 0.05. The blot signals are cropped from the full-length blot images in Additional file 2: Figure S2 and Additional file 3: Figure S3
