The WOX (WUSCHEL-related homeobox) gene family plays pivotal roles in plant growth, development, and responses to biotic/abiotic stresses. Flax (Linum usitatissimum L.), a globally important oilseed fiber crop, lacks comprehensive characterization of its family. Here, 18 LuWOX genes were systematically identified the flax genome through bioinformatics analyses. Phylogenetic classification grouped these into three clades: Ancient, Intermediate, WUS Clades, with members within same clade exhibiting conserved exon–intron structures motif compositions. Promoter analysis revealed abundant cis-acting elements associated hormone (MeJA, abscisic acid) abiotic stress adaptation (anaerobic induction, drought, low temperature). Segmental duplication events (nine pairs) contributed significantly expansion. Protein–protein interaction networks implicated several proteins stress-responsive pathways. Expression profiling demonstrated that most highly expressed 5-day-post-anthesis (DPA) flowers embryonic tissues. qRT-PCR validation further uncovered distinct expression patterns under cold, salt This study established foundational framework for leveraging enhance tolerance breeding functional genomics.

Abstract Barley ( Hordeum vulgare ) has a wide range of seed dormancy. Seed dormancy is crucial trait for plant survival and crop production. To explore genes functions associated with the difference in barley dormancy, we performed differentially expressed gene ontology (GO) enrichment analyses on embryos from wild accession H602 strong cultivated malting Kanto Nakate Gold (KNG) weak reciprocal crosses between two × KNG H602. RNA was extracted seeds harvested at physiological maturity dried 1 week. We also assessed expression levels known quantitative locus linked to In KNG, 417 showed significantly higher than H602, 14 GO terms enriched, including stress response sugar metabolism. Genes involved DNA repair were enriched highly KNG. 198 60 development auxin transport. translation Our findings indicated that abiotic response, metabolism, would be whereas barley.
