Journal ArticleDOI
Cellular organisation of the Arabidopsis thaliana root
Liam Dolan,Kees Janmaat,Viola Willemsen,Paul Linstead,Scott Poethig,Keith Roberts,Ben Scheres +6 more
TL;DR: The anatomy of the developing root of Arabidopsis is described using conventional histological techniques, scanning and transmission electron microscopy and a model of meristem activity is proposed, which underpins future work on the developmental genetics of root morphogenesis.
Journal ArticleDOI
Clonal relationships and cell patterning in the root epidermis of Arabidopsis
Liam Dolan,Catherine M. Duckett,Claire S. Grierson,Paul Linstead,Katharina Schneider,Emily Lawson,Caroline Dean,Scott Poethig,Keith Roberts +8 more
TL;DR: Ectopic hairs are present in the ctr1 root epidermis suggesting that a Raf protein kinase may play a role in pattern formation/differentiation in theroot epider Mis and that ethylene may be a diffusible signal involved in specifying pattern in the root epidersmis.
Journal ArticleDOI
Trans-acting siRNA-mediated repression of ETTIN and ARF4 regulates heteroblasty in Arabidopsis
Christine Hunter,Matthew R. Willmann,Gang Wu,Manabu Yoshikawa,María de la Luz Gutiérrez-Nava,Scott Poethig +5 more
TL;DR: It is concluded that the precocious phenotype of zip is attributable to the absence of tasiR-ARF-mediated repression of ETT and ARF4, a ta-siRNA that targets both ETT/ARF3 and ARf4.
Journal ArticleDOI
Genetic mosaics and cell lineage analysis in plants.
TL;DR: The use of genetic mosaics for cell lineage analysis has revealed several important features of plant development, including polyclonal organs in higher plants, and cell fate appears to be determined by the final location of a cell rather than by its history.
Journal ArticleDOI
Transformation of shoots into roots in Arabidopsis embryos mutant at the TOPLESS locus.
Jeff A. Long,Scott T. Woody,Scott T. Woody,Scott Poethig,Scott Poethig,Elliot M. Meyerowitz,Elliot M. Meyerowitz,M. Kathryn Barton,M. Kathryn Barton +8 more
TL;DR: A novel phenotype in Arabidopsis embryos homozygous for the temperature-sensitive topless-1 mutation causes the transformation of the shoot pole into a root, demonstrating that the topless 1 mutation is capable of causing structures specified as shoot to be respecified as root.
