miRNA164-directed cleavage of ZmNAC1 confers lateral root development in maize (Zea maysL.)

Abstract

Our results indicate one possible pathway in maize by which differences in miR164b promoter activity resulted in a different expression pattern for mature miR164 which negatively regulates ZmNAC1 expression in 87-1 and Zong3, thereby contributing to a significantly different lateral root phenotype.
