Genome-Wide Identification and Functional Characterization of New Serotonin N-Acetyltransferases in Soybean.

ABSTRACT: Melatonin is recognized as a crucial plant hormone due to its significant role in plant development, growth promotion, enhancing antioxidant activity, and stress resistance. Soybean is one of the most important crops globally. To date, three SNAT genes have been cloned in Arabidopsis and rice; however, only one gene, GmSNAT1, has been characterized in soybeans. In this study, members of the GmGNAT family were identified through genome-wide analysis. Two candidate GmSNAT genes (GmSNAT3.1 and GmSNAT3.2) were selected based on phylogenetic tree analysis and exhibited highly similar protein tertiary structures to ZmSNAT3. Furthermore, the functionality of these two GmSNAT genes was confirmed for synthesizing N-acetylserotonin or melatonin using serotonin or 5-methoxytrypta
