MYB transcription factors TFs lt br gt which compose one of the largest TF families play an important role in abiotic stress responses. lt br gt Result We identified 139 soybean MYB-related genes these genes were divided into six groups based on their lt br gt conserved domain and were distributed among 20 chromosomes Chrs . Quantitative real-time PCR qRT-PCR lt br gt indicated that GmMYB118 highly responsive to drought salt and high temperature stress thus this gene was lt br gt selected for further analysis. Subcellular localization revealed that the GmMYB118 protein located in the nucleus. lt br gt Ectopic expression EX of GmMYB118 increased tolerance to drought and salt stress and regulated the expression lt br gt of several stress-associated genes in transgenic Arabidopsis plants. Similarly GmMYB118-overexpressing OE soybean lt br gt plants generated via Agrobacterium rhizogenes A. rhizogenes -mediated transformation of the hairy roots showed lt br gt improved drought and salt tolerance. Furthermore compared with the control CK plants the clustered regularly lt br gt interspaced short .
