Abstract:

Proline accumulation is a striking feature of drought sensitive wheat cultivar HD2428 under control and salt stress conditions. HD2428 combats reactive oxygen species (ROS) using proline accumulation capacity under normal conditions for growth and development. This accumulation was enhanced by oxidative stresses (H2O2 and NaCl treatments) in flag leaves of HD2428. Proline contents were lowered under combination of the oxidative treatments in both wheats. Proline contents were low in drought tolerant wheat cultivar C306. Drought tolerant wheat cultivar C306 utilized Ascorbate-glutathione reductase (GR) located at chloroplast to prevent oxidative damage under normal growth conditions. Oxidative stress under sodium chloride salt (NaCl) treatment induced mitochondrial and cytoplasmic GR in flag leaves of HD2428; chloroplast and cytoplasmic GR in C306 flag leaves to combat excess of ROS. Stimulation of Ribulose bisphosphate carboxylase/oxygenase large subunit (Rubisco LSU) in drought tolerant wheat cultivar C306 in root and shoot indicated transcriptional changes under salt stress. Alterations in proline levels and GR isoforms were correlated and suggested changes in GR at translational levels in chloroplast, mitochondria and cytosol.
