Comparison of tissue-specific expression of OsNCED3 and OsNCED4 promoters in transgenic rice plants under salt stress. a PCR analysis of OsNCED3::GUS or OsNCED4::GUS constructs in N3P or N4P transgenic rice plants, respectively. b GUS staining in roots of 7-day-old, solution-grown transgenic rice seedlings treated with (+ NaCl) or without (− NaCl) 150 mM NaCl. c GUS staining in leaf blade and leaf sheath of 7-day-old, transgenic rice seedlings grown in solution with or without 150 mM NaCl. d GUS staining in root segments of 7-day-old transgenic rice seedlings grown in solution with or without 150 mM NaCl
