Auxin Response Factors promote organogenesis by chromatin-mediated repression of the pluripotency gene SHOOTMERISTEMLESS

In our most recent investigation of how local auxin maxima are interpreted at the inflorescence shoot apex postdoc Yuhee Chung implicates a repressor complex comprised of YABBY and class B ARF transcription factors and the histone deacetylase HDA19 in organogenesis. FIL and ETT/ARF4 directly repress the pluripotency genes  STM and BP and silencing of these genes is required for initiation of flower primordia.
