Journal ArticleDOI
Cytokinin-Deficient Transgenic Arabidopsis Plants Show Multiple Developmental Alterations Indicating Opposite Functions of Cytokinins in the Regulation of Shoot and Root Meristem Activity
TL;DR: The results are consistent with the hypothesis that cytokinins have central, but opposite, regulatory functions in root and shoot meristems and indicate that a fine-tuned control of catabolism plays an important role in ensuring the proper regulation of cytokinin functions.
Journal ArticleDOI
The Role of Auxin, pH, and Stress in the Activation of Embryogenic Cell Division in Leaf Protoplast-Derived Cells of Alfalfa
Taras Pasternak,Els Prinsen,Ferhan Ayaydin,Pál Miskolczi,Geert Potters,Han Asard,Harry Van Onckelen,Dénes Dudits,Attila Fehér +8 more
TL;DR: The involvement of stress responses, endogenous auxin synthesis, and the establishment of cellular pH gradients in the formation of the embryogenic cell type is proposed.
Journal ArticleDOI
Targeted interactomics reveals a complex core cell cycle machinery in Arabidopsis thaliana
Jelle Van Leene,Jens Hollunder,Dominique Eeckhout,Geert Persiau,Eveline Van De Slijke,Hilde Stals,Gert Van Isterdael,Aurine Verkest,Sandy Neirynck,Yelle Buffel,Stefanie De Bodt,Steven Maere,Kris Laukens,Anne Pharazyn,Paulo Cg Ferreira,Nubia Barbosa Eloy,Nubia Barbosa Eloy,Charlotte Renne,Christian Meyer,Jean-Denis Faure,Jens Steinbrenner,Jim Beynon,John C. Larkin,Yves Van de Peer,Pierre Hilson,Martin Kuiper,Lieven De Veylder,Harry Van Onckelen,Dirk Inzé,Erwin Witters,Erwin Witters,Geert De Jaeger +31 more
TL;DR: Plants have evolved a combinatorial toolkit consisting of at least 92 different CDK–cyclin complex variants, which strongly underscores the functional diversification among the large family of cyclins and reflects the pivotal role of cell cycle regulation in the developmental plasticity of plants.
Journal ArticleDOI
A Role for Auxin Redistribution in the Responses of the Root System Architecture to Phosphate Starvation in Arabidopsis
Philippe Nacry,Geneviève Canivenc,Bertrand Muller,Abdelkrim Azmi,Harry Van Onckelen,Michel Rossignol,Patrick Doumas +6 more
TL;DR: Both the strong effect of 2,3,5-triiodobenzoic acid and the phenotype of the auxin-transport mutants suggest that low P availability modifies local auxin concentrations within the root system through changes in auxin transport rather than auxin synthesis.
Journal ArticleDOI
A Tandem Affinity Purification-based Technology Platform to Study the Cell Cycle Interactome in Arabidopsis thaliana
Jelle Van Leene,Jelle Van Leene,Hilde Stals,Hilde Stals,Dominique Eeckhout,Dominique Eeckhout,Geert Persiau,Geert Persiau,Eveline Van De Slijke,Eveline Van De Slijke,Gert Van Isterdael,Gert Van Isterdael,Annelies De Clercq,Annelies De Clercq,Eric Bonnet,Eric Bonnet,Kris Laukens,Noor Remmerie,Kim Henderickx,Thomas De Vijlder,Azmi Abdelkrim,Anne Pharazyn,Harry Van Onckelen,Dirk Inzé,Dirk Inzé,Erwin Witters,Geert De Jaeger,Geert De Jaeger +27 more
TL;DR: The development and application of a high throughput tandem affinity purification/mass spectrometry platform for cell suspension cultures to analyze cell cycle-related protein complexes in Arabidopsis thaliana is described and 28 new molecular associations are identified and confirmed.
