1969 WANG Ling-shuang et al. Journal of Integrative Agriculture 2018, 17(9): 1959–1971 reported that overexpression of GmCBL1 in Arabidopsis enhances tolerances to both salt and drought stresses in transgenic plants. Thus, GmCBL1 , like AtCBL1 , may function as a positive regulator in salt and drought stress signaling pathways (Li et al. 2012). As shown in Fig. 7-D, transgenic lines showed high GmCBL1 mRNA levels under salt and drought stresses, indicating that GmBIN2 may be involved in the induction of the GmCBL1 gene in the stress- signaling pathways in response to salt and drought stresses. 5. Conclusion Here, we characterized the soybean GmBIN2 gene, a member of the GSK3/SHAGGY-like kinase family. The GmBIN2 transcripts were able to be induced by salt and drought stresses. Our data clearly demonstrated that GmBIN2 could enhance salt and drought tolerance in Arabidopsis and soybean hairy roots. At present, research regarding GmBIN2 is at an elementary stage and additional investigations are needed to elucidate its exact mechanism during stress response. Further study may focus on the molecular level including probable cross-talk among various signaling pathways to clarify its involvement in environmental abiotic stress response.
