LONELY GUY (LOG) is a pivotal cytokinin-activating enzyme that plays an important role in plant growth, development, and stress responses. Walnut (<i>Juglans regia</i>), an important woody oilseed species, has not yet undergone systematic identification of its <i>LOG</i> gene family. In this study, we identified 17 <i>JrLOG</i> genes in the walnut genome, which are unevenly distributed across 11 chromosomes. <i>JrLOG</i> gene expansion was primarily driven by gene duplication, along with purifying selection. Members of the JrLOG family were categorized into five groups, each exhibiting analogous gene structures, featured motifs, and conserved domains. Transcriptome and quantitative real-time PCR analyses revealed that <i>JrLOG</i> gene expression was tissue-specific, developmentally regulated, and responsive to stress situations. Notably, <i>JrLOG3</i>, which localizes to the cell membrane, exhibited high expression levels in leaves and responded to both cold and pathogen infection treatments. This study represents the first comprehensive identification of the <i>LOG</i> gene family in walnut, offering essential data for further functional studies of this gene family.
