Chenopodium quinoa is an emerging halophyte plant that has gained signifcant attention from researchers in recent years due to its high nutritional value and resilience to environmental stress. This plant serves as an excellent substitute for rice and wheat. However, there has been limited research on it, leaving many of its genes still unidentifed. The objective of this research was to identify gene patterns and conduct a bioinformatics analysis across various felds. The expression sequence of the betaine aldehyde dehydrogenase (BADH) gene was predicted using bioinformatics software such as PlantCARE and PlantPan. The fndings indicated that diferent cultivars provide valuable information regarding resistance to the binding sites of MYB transcription factors, hormone response regions, and both promoter and enhancer regions, which contain 32 cisregulatory elements. This emphasized the role of the BADH gene in responding to abiotic stress. Additionally, the research revealed that the BADH gene activates oxidoreductase activity across diferent cultivars, infuencing NAD or NADP receptors that contribute to stress resistance. The protein lengths identifed were 454 and 500 amino acids, respectively. Chloroplast analysis revealed that the GC content for the BADH gene was 37%. From this analysis, it was determined that out of 128 distinct functional genes in the genome, approximately 84 are protein-coding genes. An examination of the domains and motifs in the target genes showed that they contain two conserved sequences: Aldedh and DUF1487. Furthermore, miRNA analysis and promoter investigations indicated that the BADH gene plays a vital role in activating processes related to arginase, protein kinases, superoxide dismutase, tubulins, and membrane proteins. The gene is also crucial for activating nuclear transcription factors through receptor activation. In conclusion, the results suggest that BADH genes contribute to the plant's resistance to salt stress through various mechanisms. Stress acts as a trigger for the activation of this gene, efectively safeguarding the plant against the detrimental efects of environmental stresses.
