Organizer-Derived WOX5 Signal Maintains Root Columella Stem Cells through Chromatin-Mediated Repression of CDF4 Expression
Limin Pi,Ernst Aichinger,Eric van der Graaff,Cristina I. Llavata-Peris,Dolf Weijers,Lars Hennig,Edwin P. Groot,Thomas Laux +7 more
TL;DR: This work shows that in the Arabidopsis root meristem, the WOX5 protein moves from the root niche organizer, the quiescent center, into the columella stem cells, where it directly represses the transcription factor gene CDF4.

Plant Stem Cell Niches
TL;DR: This review focuses on current models in plant stem cell research elaborated during the past two decades, mainly in the model plant Arabidopsis thaliana, and addresses the roles of mobile signals on transcriptional modules involved in balancing cell fates.

WOX5 Suppresses CYCLIN D Activity to Establish Quiescence at the Center of the Root Stem Cell Niche
Celine Forzani,Ernst Aichinger,Emily Sornay,Viola Willemsen,Thomas Laux,Walter Dewitte,James A. H. Murray +6 more
TL;DR: A new role for WOX5 is revealed in restraining cell division in the cells of the QC, thereby establishing quiescence and excluding CYCD activity from the QC.

CHD3 Proteins and Polycomb Group Proteins Antagonistically Determine Cell Identity in Arabidopsis
TL;DR: It is reported that the chromodomain/helicase/DNA–binding domain CHD3 proteins PICKLE (PKL) and PICKle RELATED2 (PKR2) have trxG-like functions in plants and are required for the expression of many genes that are repressed by PcG proteins.
The CHD3 Chromatin Remodeler PICKLE and Polycomb Group Proteins Antagonistically Regulate Meristem Activity in the Arabidopsis Root
Ernst Aichinger,Ernst Aichinger,Corina B. R. Villar,Riccardo Di Mambro,Sabrina Sabatini,Claudia Köhler,Claudia Köhler +6 more
TL;DR: It is reported that the chromatin remodeling factor PICKLE (PKL) and the PcG protein CURLY LEAF (CLF) antagonistically determineRoot meristem activity is largely controlled by the antagonistic activity of P cG proteins and PKL.
