Assessment of salinity and drought tolerance of <i>PgGPx</i> overexpressing T₁ transgenic seedlings.

<p>Growth of the transgenic as well as WT rice plants grown under control condition (A) or in the presence 200 mM NaCl (B) or 150 mM mannitol (C). Comparison of shoot length (D) and fresh weight (E) of transgenic vis-a-vis WT plants under salinity and drought stresses showed that transgenic plants had better physiological growth. Analysis of cellular damage in response to salinity and drought were measured by electrolytic leakage (F). Relative H₂O₂ and O^2- accumulation in the transgenic and WT plants under salinity and drought stresses were assessed by histochemical staining. Total H₂O₂ and O^2- levels were visualized by 3,3 0-diaminobenzidine (DAB) staining (G) and nitro blue tetrazolium (NBT) staining (H), respectively.
