ABSTRACT = {<i>NAC </i>(NAM, ATAF, CUC) is a class of transcription factors involved in plant growth regulation, abiotic stress
responses, morphogenesis and metabolism. <i>Salvia miltiorrhiza</i> is an important Chinese medicinal herb, but the
characterization of <i>NAC</i> genes in this species is limited. In this study, based on the <i>Salvia miltiorrhiza</i> genomic
databases, 82 <i>NAC</i> transcription factors were identified, which were divided into 14 groups. Meanwhile, phylogenetic
analysis, gene structure, chromosomal localization and potential role of <i>SmNACs</i> in abiotic stress conditions were also
studied. The results revealed that some <i>SmNACs</i> had different structures than others, which advised that these genes
may have multiple/distinct functions. Real-time quantitative polymerase chain reaction (RT-qPCR) analysis showed
that <i>SmNACs</i> exhibited differential expression patterns under salt and drought stress. The NaCl induced salinity
treatments modulated the expression of several <i>SmNAC</i> genes more in roots compared with leaves. Conversely, under
drought stress conditions, more genes were upregulated in leaves compared with roots. These results will be useful for
the further study involved in the functional characteristics of <i>SmNAC</i> genes, especially in response to salt and drought
stresses, thereby may facilitate genetic breeding in <i>Salvia miltiorrhiza</i>.},
