Journal ArticleDOI
A novel aux/IAA28 signaling cascade activates GATA23-dependent specification of lateral root founder cell identity.

Overvoorde,Leentje Jansen,Steffen Vanneste,Barbara Möller,Michael Wilson,Tara J. Holman,Gert Van Isterdael,Géraldine Brunoud,Géraldine Brunoud,Marnik Vuylsteke,Teva Vernoux,Teva Vernoux,Lieven De Veylder,Dirk Inzé,Dolf Weijers,Malcolm J. Bennett,Tom Beeckman +24 more
TL;DR: The first molecular components that control lateral root founder cell identity in the Arabidopsis root are identified, including an IAA28-dependent auxin signaling module in the basal meristem region that regulates GATA23 expression and thereby lateral rootfounder cell specification and root branching patterns.
Journal ArticleDOI
Chemical Inhibition of a Subset of Arabidopsis thaliana GSK3-like Kinases Activates Brassinosteroid Signaling
Bert De Rybel,Dominique Audenaert,Grégory Vert,Wilfried Rozhon,Juliane Mayerhofer,Frank Peelman,Silvie Coutuer,Tinneke Denayer,Leentje Jansen,Long Nguyen,Isabelle Vanhoutte,Gerrit T.S. Beemster,Gerrit T.S. Beemster,Kris Vleminckx,Claudia Jonak,Joanne Chory,Dirk Inzé,Eugenia Russinova,Tom Beeckman +18 more
TL;DR: The data suggest that GSK3 inhibition is the sole activation mode of BR signaling and argues against GSK2-independent BR responses in Arabidopsis, and bikinin represents a useful tool to further unravel regulatory mechanisms.
Journal ArticleDOI
Transcription factor WRKY23 assists auxin distribution patterns during Arabidopsis root development through local control on flavonol biosynthesis
Wim Grunewald,Ive De Smet,Daniel R. Lewis,Christian Löfke,Leentje Jansen,Geert Goeminne,Robin Vanden Bossche,Mansour Karimi,Bert De Rybel,Bartel Vanholme,Thomas Teichmann,Wout Boerjan,Marc Van Montagu,Godelieve Gheysen,Gloria K. Muday,Jiří Friml,Tom Beeckman +16 more
TL;DR: Using reduction-of-function and overexpression approaches in parallel, it is demonstrated that the WRKY23 transcription factor is needed for proper root growth and development by stimulating the local biosynthesis of flavonols.
Journal ArticleDOI
A role for the root cap in root branching revealed by the non-auxin probe naxillin
Bert De Rybel,Dominique Audenaert,Wei Xuan,Paul J. Overvoorde,Lucia C. Strader,Lucia C. Strader,Stefan Kepinski,Rebecca C. Hoye,Ronald G. Brisbois,Boris Parizot,Steffen Vanneste,Xing Liu,Xing Liu,Alison D. Gilday,Ian A. Graham,Long Nguyen,Leentje Jansen,Maria Fransiska Njo,Dirk Inzé,Bonnie Bartel,Tom Beeckman +20 more
TL;DR: A small-molecule screen in Arabidopsis thaliana is described that identified naxillin as what is to the authors' knowledge the first non-auxin-like molecule that promotes root branching and uncovered the involvement of the root cap in root branching.
Journal ArticleDOI
Auxin Influx Activity Is Associated with Frankia Infection during Actinorhizal Nodule Formation in Casuarina glauca
Benjamin Péret,Ranjan Swarup,Leentje Jansen,Gaëlle Devos,Florence Auguy,Myriam Collin,Carole Santi,Valérie Hocher,Claudine Franche,Didier Bogusz,Malcolm J. Bennett,Laurent Laplaze +11 more
TL;DR: The data suggest that auxin plays an important role during plant cell infection in actinorhizal symbioses and homologs of the auxin influx carrier (AUX1-LAX) genes in Casuarina glauca are isolated and characterized.
