NF-YA transcription factors function in modulating tolerance to abiotic stresses that are serious threats to crop yields. In this study, GmNFYA13, an NF-YA gene in soybean, was strongly induced by salt, drought, ABA, and H₂O₂, and suppressed by tungstate, an ABA synthesis inhibitor. The GmNFYA13 transcripts were detected in different tissues in seedling and flowering stages, and the expression levels in roots were highest. GmNFYA13 is a nuclear localization protein with self-activating activity. Transgenic Arabidopsis plants overexpressing GmNFYA13 with higher transcript levels of stress-related genes showed ABA hypersensitivity and enhanced tolerance to salt and drought stresses compared with WT plants. Moreover, overexpression of GmNFYA13 resulted in higher salt and drought tolerance in OE soybean plants, while suppressing it produced the opposite results. In addition, GmNFYA13 could bind to the promoters of GmSALT3, GmMYB84, GmNCED3, and GmRbohB to regulate their expression abundance in vivo. The data in this study suggested that GmNFYA13 enhanced salt and drought tolerance in soybean plants.

NF-YA转录因子在调节对非生物胁迫的耐受性中，非生物胁迫对作物的产量构成严重威胁。在这个研究中，GmNFYA13大豆中的NF-YA基因NF-YA被盐，干旱，ABA和H ₂ O ₂强烈诱导，并被ABA合成抑制剂钨酸盐抑制。的GmNFYA13在苗期和开花期不同组织中检测到转录本，根中的表达水平最高。GmNFYA13是具有自激活活性的核定位蛋白。转基因拟南芥 植物过表达 GmNFYA13与野生型植物相比，胁迫相关基因转录水平较高的植物表现出ABA超敏性，对盐和干旱胁迫的耐受性增强。此外，GmNFYA13的过表达导致OE大豆植物具有更高的盐分和干旱耐受性，而抑制它会产生相反的结果。此外，GmNFYA13可以结合到的启动子GmSALT3， GmMYB84， GmNCED3和 GmRbohB 调节他们的表情丰富度 体内。这项研究的数据表明GmNFYA13 增强大豆植物的耐盐和干旱能力。
