The impact of global warming is increasing and thus exacerbating environmental stresses that affect plant yield and distribution, including the <i>Eriobotrya japonica</i> Lindl (Loquat tree). <i>Eriobotrya japonica</i>, a member of the Rosaceae family, is valued not only for its nutritious fruit but also for its medicinal purposes, landscape uses, and other pharmacological benefits. Nonetheless, the productivity of <i>Eriobotrya japonica</i> has raised a lot of concern in the wake of adverse environmental conditions. Understanding the characteristics of the <i>LRR-RLK</i> gene family in loquat is crucial, as these genes play vital roles in plant stress responses. In this study, 283 <i>LRR-RLK</i> genes were identified in the genome of <i>E. japonica</i> that were randomly positioned on 17 chromosomes and 24 contigs. The 283 EjLRR-RLK proteins clustered into 21 classes and subclasses in the phylogenetic analysis based on domain and protein arrangements. Further explorations in the promoter regions of the <i>EjLRR-RLK</i> genes showed an abundance of cis-regulatory elements that functioned in growth and development, phytohormone, and biotic and abiotic responses. Most cis-elements were present in the biotic and abiotic responses suggesting that the <i>EjLRR-RLK</i> genes are invested in regulating both biotic and abiotic stresses. Additional investigations into the responses of <i>EjLRR-RLK</i> genes to abiotic stress using the RT-qPCR revealed that <i>EjLRR-RLK</i> genes respond to abiotic stress, especially heat and salt stresses. Particularly, <i>EjapXI-1.6</i> and <i>EjapI-2.5</i> exhibited constant upregulation in all stresses analyzed, indicating that these may take an active role in regulating abiotic stresses. Our findings suggest the pivotal functions of <i>EjLRR-RLK</i> genes although additional research is still required. This research aims to provide useful information relating to the characterization of <i>EjLRR-RLK</i> genes and their responses to environmental stresses, establishing a concrete base for the following research.
