"Study identified a nitrogen-responsive signaling module that comprises both xyloglucan endotransglucosylase 9 (XTH9) and the Dof transcription factor OBP4 and controls lateral root (LR) development in Arabidopsis. OBP4 bound to the promoter of XTH9 to suppress XTH9 expression to antagonistically control XTH9 expression. OBP4-XTH9 module elaborately sustains LR development in response to nitrate treatment."xsd:string
