ABSTRACT = {Plant U-box (PUB) E3 ubiquitin ligases play important roles in hormone signaling pathways and in response to different abiotic stresses, but little is known about <i>U-box</i> genes in Danshen (root of <i>Salvia miltiorrhiza</i> Bunge). Here, we identified and characterized 70 <i>SmPUB</i> genes based on its genome sequence. Phylogenetic analysis of U-box genes from <i>S. miltiorrhiza</i> and <i>Arabidopsis</i> suggested that they can be clustered into seven subgroups (I–VII). Typical <i>U-box</i> domains were found in all identified <i>SmPUB</i> genes through the analysis of conserved motifs. Moreover, qRT-PCR was applied to analyze the relative expression levels of <i>U-box</i> genes in <i>S. miltiorrhiza</i> roots and leaves under PEG-induced water deficit and salt stresses. Results revealed that the <i>SmPUB</i> genes exhibited stronger response to drought than to salt stress. To the best of our knowledge, this report is the first to perform genome-wide identification and analysis of the <i>U-box</i> gene family in <i>S. miltiorrhiza</i>, and the results provide valuable information for better understanding of the function of <i>U-box</i> in <i>S. miltiorrhiza</i>.},
