Journal ArticleDOI
Pluripotency of Arabidopsis xylem pericycle underlies shoot regeneration from root and hypocotyl explants grown in vitro
Ramzy Atta,Lieve M.L. Laurens,Elodie Boucheron-Dubuisson,Anne Guivarc'h,Eugénie Carnero,Véronique Giraudat-Pautot,Philippe Rech,Dominique Chriqui +7 more
TL;DR: It appeared that the xylem pericycle is more pluripotent than previously thought, and was accompanied by the ability of pericycle derivatives to retain diploidy, even after several rounds of cell division, while the phloem pericycle did not display such developmental plasticity.
Journal ArticleDOI
Induction of male sterility in plants by metabolic engineering of the carbohydrate supply.
TL;DR: A critical role of extracellular invertase in pollen development is demonstrated and this result strongly supports the essential function ofextracellular sucrose cleavage for supplying carbohydrates to sink tissues via the apoplast.
Journal ArticleDOI
Cytokinin deficiency causes distinct changes of sink and source parameters in tobacco shoots and roots.
Tomáš Werner,Kerstin Holst,Yvonne Pörs,Anne Guivarc'h,Angelika Mustroph,Dominique Chriqui,Bernhard Grimm,Thomas Schmülling +7 more
TL;DR: Results strongly support a function of cytokinin in regulating shoot sink strength and its reduction may be a cause of the altered shoot phenotype.
Journal ArticleDOI
Local expression of the ipt gene in transgenic tobacco (Nicotiana tabacum L. cv. SR1) axillary buds establishes a role for cytokinins in tuberization and sink formation
Anne Guivarc'h,Jacques Rembur,Marc Goetz,Thomas Roitsch,Michèle Noin,Thomas Schmülling,Dominique Chriqui +6 more
TL;DR: The results underline the role of cytokinins in cell cycle regulation and in the creation of a sink--source effect and provide new information about cytokinin involvement in the process of tuberization and their overproduction in axillary buds giving rise to tuberized lateral branches in a naturally non-tuberizing species.
Journal ArticleDOI
TUMOROUS SHOOT DEVELOPMENT (TSD) genes are required for co-ordinated plant shoot development
Markus Frank,Anne Guivarc'h,Eva Krupková,Irina Lorenz-Meyer,Dominique Chriqui,Thomas Schmülling +5 more
TL;DR: It is hypothesize that the TSD gene products negatively regulate cytokinin-dependent meristematic activity during vegetative development of Arabidopsis thaliana.
