Mentha longifolia is a valuable medicinal plant rich in bioactive compounds such as flavonoids, phenolic acids, terpenes, and sesquiterpenes, widely used in pharmaceutical and food industries. WRKY transcription factors (TFs) form one of the largest gene regulatory families in plants and are involved in key biological processes, including stress responses, secondary metabolism, and development. In this study, we performed a genome-wide analysis of the M. longifolia proteome using WRKY Hidden Markov Model (HMM) profile to identify and classify WRKY transcription factors. A total of 53 WRKY genes were identified and categorized into Groups I (10 genes), II (34), III (3), and an unknown group (6). Group II was further divided into five subgroups (IIa–IIe), with subgroup IIc being the largest. Phylogenetic analysis grouped the WRKY proteins into seven clades (A–G), showing close evolutionary relationships with corresponding WRKYs in Arabidopsis thaliana, suggesting possible functional conservation. This study provides a foundation for future research on the functional roles of WRKY genes in M. longifolia.
