摘要: PLETHORA 1 (PLT1) and PLT2 are two key transcription factors that regulate the root apical meristem. It is found that AUXIN RESPONSE FACTOR2 (ARF2) negatively mediates stability of PLT2 protein. Conditional overexpression of PLT2 largely promotes cell division and completely inhibits cell differentiation in root meristems of the arf2 mutant.
