TEM and SEM-based anatomical analysis of WT and OsHBP1b over-expressing plants under control and salinity stress. a Structure of complete cell of WT (1st row) and OsHBP1b over-expressing plants (2nd row) under control (1st column) and after 200 mM NaCl treatment (2nd column) as observed under TEM. Third and fourth column are showing the structure of a single chloroplast and organisation of thylakoid under control and salinity conditions in WT and over-expressing plants. b SEM picture showing the structure of stomata in WT and OsHBP1b over-expressing plants under control and salinity stress. Note that under salinity, the stomata of OsHBP1b over-expressing plants are protected. Cp, chloroplast; N, nucleus; T, thylakoid. Green and red arrows indicate stomata and silica cell respectively
