One of the environmental stresses is drought that harm the production of many cereals and every year due to low rainfall and frequent droughts, the need to produce plants resistant to this stress is felt. Therefore, identification and evaluation of the genes involved in the production of this resistance in plants are of great importance. By identifying these genes and changing their expression, it is possible to produce resistant plants that can tolerate dehydration and drought, with at least a qualitative and quantitative reduction in yield.</div></div><div id="abs0010" style="margin: 0px; padding: 0px; color: rgb(31, 31, 31); font-family: ElsevierGulliver, Georgia, "Times New Roman", Times, STIXGeneral, "Cambria Math", "Lucida Sans Unicode", "Microsoft Sans Serif", "Segoe UI Symbol", "Arial Unicode MS", serif, sans-serif; font-size: 16px;"><h3 class="u-h4 u-margin-m-top u-margin-xs-bottom" id="sect0015" style="margin-right: 0px; margin-left: 0px; padding: 0px; margin-top: 24px !important; margin-bottom: 8px !important; font-size: 20px !important; line-height: 30px !important;">Results</h3><div class="u-margin-s-bottom" id="sp0095" style="margin-top: 0px; margin-right: 0px; margin-left: 0px; padding: 0px; margin-bottom: 16px !important;">Based on the meta-analysis results obtained in this study, in resistant cultivars ~ 4% (2394/61290) of the probe IDs decreased and ~ 4.5% (2670/61290) increased expression, furthermore in susceptible cultivars ~ 7% (4183/61290) of probe IDs decreased and ~ 6% (3591/61290) increased expression (<em style="margin: 0px; padding: 0px;">P</em><span style="margin: 0px; padding: 0px;"> value ≤ 0.05). List of up- and downregulated genes was revealed, among the expressed genes of transcription factors Myb3, ethylene-responsive 5a, MIKC-type MADS-box WM24B, and salinity inducible ERF4 in resistant cultivars and transcription factors WRKY15, MADS-box TaAGL8, WRKY39, and Myb in susceptible cultivars, they showed a significant increase in expression, these transcription factors are of great importance in drought stress. Among them, ethylene responsive 5a in resistant cultivars by 3 times and Myb in susceptible cultivars by 2.6 times have shown the highest expression change.

These genes can distinguish between different susceptible and resistant wheat cultivars.</div></div>
