At TSPO accumulation and chloroplast localization upon salt stress. (A) Immunoblot analysis of OxAtTSPO:eGFP (OxM1TSPO:eGFP, OxM21TSPO:eGFP and OxM42TSPO:eGFP) fusion proteins detected in plants with an antibody to GFP. Plants were untreated, or treated with 150 mM NaCl. As a control wild-type plants and plants over-expressing GFP (OxeGFP) seedlings were used. (B) Anti-GFP immunoblot of trypsinized chloroplasts from Arabidopsis plants either untreated or treated with 150 mM NaCl. Control immunoblots were probed with antibodies chloroplast proteins RuBisCo and D1; and to cytosolic UGPase. Each lane represents equal amounts of chloroplasts.
