Abstract:	Phosphoenolpyruvate carboxylase (PEPC) plays an important role in assimilating atmospheric CO2during C4and crassulacean acid metabolism photosynthesis, and also participates in various non-photosynthetic processes, including fruit ripening, stomatal opening, supporting carbonnitrogen interactions, seed formation and germination, and regulation of plant tolerance to stresses. However, a comprehensive analysis of PEPC family inGlycine maxhas not been reported. Here, a total of tenPEPCgenes were identified in soybean and denominated asGmPEPC1-GmPEPC10. Based on the phylogenetic analysis of the PEPC proteins from 13 higher plant species including soybean, PEPC family could be classified into two subfamilies, which was further supported by analyses of their conserved motifs and gene structures. Nineteencis-regulatory elements related to phytohormones, abiotic and biotic stresses were identified in the promoter regions ofGmPEPCgenes, indicating their roles in soybean development and stress responses.GmPEPCgenes were expressed in various soybean tissues and most of them responded to the exogenously applied phytohormones.GmPEPC6,GmPEPC8andGmPEPC9were significantly induced by aluminum toxicity, cold, osmotic and salt stresses. In addition, the enzyme activities of soybean PEPCs were also up-regulated by these treatments, suggesting their potential roles in soybean response to abiotic stresses.
