Various abiotic stress factors provoke protein denaturation and oxidative stress in plants, which might lead to the production of certain osmolytes including different amino acids. Amino acids act as precursors and constituents of proteins playing a paramount role in plant metabolism and development. Proline amino acid is among the chief organic osmolyte accumulating in different plant species in response to stress. Although, its definite role in plant tolerance remain debatable, it is thought to have a positive effect on cell integrity along with adaptive function in mediating osmotic adjustment in plants during stress conditions. In this study, the changes in proline accumulation in response to different stress regimes (6h, 24h and 48 h) followed by re-watering were investigated in the embryo and endosperms of different wheat cultivars. The results indicated an enhancement of proline accumulation at moderate (24h) and severe (48h) stress conditions in a genotype independent manner. Based upon our results, biochemical significance of the proline accumulating during different stress intensities and recovery is discussed.
