Proline-rich extensin-like receptor protein kinases (PERKs) are known for their roles in the developmental processes and stress responses of many plants. We have identified 30 <i>TaPERK</i> genes in the genome of <i>T. aestivum</i>, exploring their evolutionary and syntenic relationship and analyzing their gene and protein structures, various cis-regulatory elements, expression profiling, and interacting miRNAs. The <i>TaPERK</i> genes formed 12 homeologous groups and clustered into four phylogenetic clades. All the proteins exhibited a typical domain organization of PERK and consisted of conserved proline residue repeats and serine-proline and proline-serine repeats. Further, the tyrosine-x-tyrosine (YXY) motif was also found conserved in thirteen TaPERKs. The <i>cis</i>-regulatory elements and expression profiling under tissue developmental stages suggested their role in plant growth processes. Further, the differential expression of certain <i>TaPERK</i> genes under biotic and abiotic stress conditions suggested their involvement in defense responses as well. The interaction of <i>TaPERK</i> genes with different miRNAs further strengthened evidence for their diverse biological roles. In this study, a comprehensive analysis of obtained <i>TaPERK</i> genes was performed, enriching our knowledge of <i>TaPERK</i> genes and providing a foundation for further possible functional analyses in future studies.
