Abstract: NAC is a plant-specific transcription factor that plays an important role in regulating the development and response of abiotic and biotic stresses. In order to explore the function of soybean-related genes, a NAC gene GmNAC23 was cloned from soybean by PCR. The full length of GmNAC23 cDNA was 1 077 bp, including an ORF of 1 053 bp. This cDNA sequence encoded a polypepide of 350 amino acid residues with a predicted molecular mass of 39.483 ku and a basic isoelectric point of 7.08. Sequence analysis showed that the GmNAC23 genome contained three exons and two introns. Multiple sequence alignments showed that the GmNAC23 protein contained a highly conserved NAM domain. Phylogenetic analysis showed that the protein had the homology with the NAC protein of VrNAC, CaNAC and CarNAC. Transcriptional activation ability assay showed that the GmNAC23 could grow on SD (Trp-/His-/Ade-) deficient medium, indicating that the gene has transcriptional activation function in yeast. Tissue-specific expression profiles showed that GmNAC23 expressed almost in all detected tissues, and its expression level was relatively high in root and low in sam.The results indicated that the soybean GmNAC23 gene had a transcriptional activation function and was abundantly expressed in root, which laid a foundation for further study of the biological function of GmNAC23.
