摘      要：Plant AT-rich sequence and zinc binding(PLATZ)transcription factors are a class of plant specific zincdependent DNA-binding proteins that function in abiotic stress response and plant *** this study,31 GmPLATZ genes were identified in ***17 was down-regulated by drought and exogenous abscisic *** Arabidopsis and soybean hairy roots overexpressing GmPLATZ17 showed drought sensitivity and inhibition of stress-associated gene *** contrast,suppressed expression of GmPLATZ17 led to increased drought tolerance in transgenic soybean hairy *** GmPLATZ17 protein was verified to interact physically with the GmDREB5 transcription factor,and overexpression of GmDREB5 increased drought tolerance in soybean hairy *** of GmPLATZ17 with GmDREB5 was shown to interfere with the DRE-binding activity of GmDREB5,suppressing downstream stress-associated gene *** results show that GmPLATZ17 inhibits drought tolerance by interacting with *** study sheds light on PLATZ transcription factors and the function of GmPLATZ17 in regulating drought sensitivity.
