Cuticle wax consists of very-long-chain fatty acids (VLCFAs) and their derivatives. β-Ketoacyl-CoA synthase (<i>KCS</i>) is a key enzyme in the synthesis of VLCFAs and provides a precursor for the synthesis of cuticle wax, but the <i>KCS</i> gene family was yet to be reported in the passion fruit (<i>Passiflora edulis</i>). In this study, thirty-two <i>KCS</i> genes were identified in the passion fruit genome and phylogenetically grouped as <i>KCS1</i>-like, <i>FAE1</i>-like, <i>FDH</i>-like, and <i>CER6</i>-like. Furthermore, thirty-one <i>PeKCS</i> genes were positioned on seven chromosomes, while one <i>PeKCS</i> was localized to the unassembled genomic scaffold.
