Abstract:   (204 Views)
This syudy was performed to study the variation in proteome pattern in leaves of  maize B73 and MO17 inbred lines under 200 mM sodium chloride salinity stress and also non stress conditions. The experiment carried out as factorial arrangements in randomized block design in hydroponic systems at the faculty of agriculture, University of Tabriz, Tabriz, Iran, in 2017. Biological yield in both lines decreased under salinity stress compared to the control. Proteome analysis of leaf tissue showed that 28 from 78 repeatable protein spots in B73 and 20 from 123 repeatable protein spots in MO17 had significant frequency variation under stress. Identification of proteins was done by pI and molecular weight. Candidate proteins involved in the pathways of metabolism and energy production, messenger and channel, cell protection and defense and proteins involved in the folding of other proteins. The highest number of stress response proteins in B73 and MO17 lines related to the pathways of metabolism and energy production, messenger and channel, and proteins involved in the folding of other proteins. In both B73 and MO17 lines, all channel and messenger proteins decreased and increased, under salinity stress, respectively. One of the most important proteins with significant frequency variation was observed for calmodulin-binding transcription activator 4 protein, which plays an important role in plant growth and responses to environmental stimuli. This protein decreased in B73 line and increased significantly in MO17 line. Development of the vascular system is prevented by reducing the channel and messenger proteins as well as the transfer of ions and toxic substances to the shoot. All proteins involved in metabolism and energy production decreased under salinity stress in B73, and in contrast, most of these proteins increased in MO17. In other words, the relative increase in these proteins lead to an increase in plant metabolism and then the plant fuels more energy to cope with stress. These results can explain, to some extents, the relative susceptibility of MO17 in comparison with B73 under salinity stress conditions.
