摘　　要：Dear Editor Soybean is an important crop for oil and protein resources but its growth and development may e6counter various abiotic stresses, including high salinity, that can hinder soybean production. Manipulation of soybean stress tolerance requires a thorough understanding of the mechanisms underlying plant response to stresses. Evolutionarily, plants have developed multiple gene regulatory mechanisms to adjust cellular activities for better survival under stress conditions, and one of these is microRNA （miRNA）-medi- ated gene silencing （Zhang, 2015）. Many conserved and novel miRNAs have been identified in different organs of soybean and in different processes during soybean development （Song et al., 2011）. However, these soybean miRNAs were seldom studied in stress response. Previously, we have identified multiple stressresponsive transcription factor genes from soybean and analyzed their functions in stress response （Wei et al., 2009; Wang et al., 2015）. Now we intend to explore the role of miRNAs in the regulation of soybean response to stresses. Among our previously identified miRNAs from soybean （Song et al., 2011）, the gma-miR172a can be induced by salt and other stresses, and so was selected for further investigation.Dear Editor Soybean is an important crop for oil and protein resources but its growth and development may e6counter various abiotic stresses, including high salinity, that can hinder soybean production.
