Serotonin N-acetyltransferase (SNAT) is a crucial enzyme in the melatonin synthesis pathway, playing an essential role both biosynthesis and plant resistance to abiotic stress. A bioinformatics approach was employed identify members of citrus SNAT gene family analyze their physicochemical properties, structure, conserved domains, phylogenetic relationships, promoter cis-acting elements. Additionally, tissue-specific expression trifoliate orange patterns under stress conditions were examined. This study identified 21 across five genomes, distributed over chromosomes, with majority predicted localize within chloroplasts. These genes characterized by having between 1 8 exons, 0 7 introns, 2 5 motifs. Phylogenetic analysis classified into four subgroups, demonstrating significant collinearity rice. Analysis regions revealed 32 elements, those responsive light, abscisic acid, drought being most common. Expression indicated tissue specificity, highest levels detected leaves. Quantitative real-time PCR showed that PtrSNAT1 notably upregulated various conditions, suggesting its response. Overall, these findings provide critical insights for further functional studies relation responses. Moreover, represents potential target developing rootstocks enhanced
