Description:
Tissue patterns are dynamically maintained. Continuous formation of plant tissues during postembryonic growth requires asymmetric divisions and the specification of cell lineages. We show that the BIRDs and SCARECROW regulate lineage identity, positional signals, patterning, and formative divisions throughout Arabidopsis root growth. These transcription factors are postembryonic determinants of the ground tissue stem cells and their lineage. Upon further activation by the positional signal SHORT-ROOT (a mobile transcription factor), they direct asymmetric cell divisions and patterning of cell types. The BIRDs and SCARECROW with SHORT-ROOT organize tissue patterns at all formative steps during growth, ensuring developmental plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moreno-Risueno, Miguel A -- Sozzani, Rosangela -- Yardimci, Galip Gurkan -- Petricka, Jalean J -- Vernoux, Teva -- Blilou, Ikram -- Alonso, Jose -- Winter, Cara M -- Ohler, Uwe -- Scheres, Ben -- Benfey, Philip N -- F32 GM086976/GM/NIGMS NIH HHS/ -- F32 GM106690-01/GM/NIGMS NIH HHS/ -- R01-GM043778/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 23;350(6259):426-30. doi: 10.1126/science.aad1171.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biotechnology, Center for Plant Genomics and Biotechnology, Universidad Politecnica de Madrid, 28223 Pozuelo de Alarcon (Madrid), Spain. ; Department of Biology and Howard Hughes Medical Institute, Duke University, Durham, NC 27708, USA. ; Laboratoire de Reproduction et Developpement des Plantes, CNRS, INRA, ENS Lyon, UCBL, Universite de Lyon, 69364 Lyon, France. ; Department of Plant Biology, Wageningen University Research, Wageningen, Netherlands. ; Department of Plant and Microbial Biology, North Carolina State University, Raleigh, NC 27695, USA. ; Berlin Institute for Medical Systems Biology, Max Delbruck Center for Molecular Medicine, 13125 Berlin, Germany. ; Department of Biology and Howard Hughes Medical Institute, Duke University, Durham, NC 27708, USA. philip.benfey@duke.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26494755" target="_blank"〉PubMed〈/a〉
