文章摘要：

Nuclear factor Y (NF-Y) is a heterotrimeric transcription factor composed of NF-YA, NF-YB and NFYC proteins. In this study, we identified and characterized a gene, GmNFYA3, which encodes the NF-YA subunit of the NF-Y complex in soybeans (Glycine max L.). Real time RT-PCR analysis indicated that GmNFYA3 was induced by abscisic acid (ABA) and abiotic stresses, such as polyethylene glycol, NaCl and cold. Subcellular localization analysis suggested that GmNFYA3 may activate its specific targets in the nucleus. Histochemical b-glucuronidase (GUS) staining revealed that the expression of the GUS gene driven by the GmNFYA3 promoter occurred in various transgenic Arabidopsis tissues. Coexpression in
