Genome-Wide Identification and Expression Analysis of the WOX Family Reveals Potential Roles in Stem Development of <i>Euphorbia hirta</i>.

ABSTRACT: The homeobox transcription factor (TF) superfamily includes the WUSCHEL-RELATED HOMEOBOX (WOX) family, which plays a critical role in adaptive plant growth. Specifically, WOX regulates stem growth in plants, with stems serving as the structural framework for laticifers in Euphorbia hirta. However, the number of WOX gene family members in the E. hirta genome has not been reported. In this study, we identified 14 EhWOX genes in E. hirta and characterized their physicochemical properties, chromosomal locations, phylogenetic relationships, conserved motifs, gene structures, promoter cis elements, gene ontology (GO) enrichment, tissue-specific expression patterns, and subcellular localization. Chromosomal mapping indicated their distribution across nine
