WRKY transcription factors (TFs) act in regulating plant growth and development as well as in response to different stress. Some earlier studies done by individual researchers reported different wheat WRKY TFs. Although, the recently released wheat genome has opened an avenue to investigate wheat WRKYs (TaWRKY) TFs. Prime objective of this study to performed genome-wide classifications of TaWRKYs and their functional annotation. The classification of 107 individual identified characterized sequences of TaWRKY (IICS-TaWRKY) and 160 uncharacterized draft sequences of TaWRKY (UDS-TaWRKY), along with their gene structures and motifs analysis was performed. Along with comparative sequence analysis and microarray analysis was performed to mimic out TaWRKYs functions in response to different abiotic stresses, accompanied by in-vitro validation. The comparative phylogenetic analysis and estimation of Ka/Ks ratio with Triticum urartu, illustrate group based clasifications of TaWRKYs and evolutionary divergences. Furthermore, motif-based and protein-DNA interaction analysis of TaWRKYs helps to identify, their putative function in target DNA recognition sites. Subsequently, results of microarray and comparative sequence analysis provides the evidence of TaWRKYs involved in heat and/or drought stress. Further, in-vitro results validates that TaWRKY014, TaWRKY090 are found to participate in response of drought stress, whereas TaWRKY008, TaWRKY122, and WRKY45 are involved in response of heat and drought stress. These findings can be utilized in developing novel heat and drought-tolerant wheat cultivars using marker-assisted breeding and transgenic development.
