Journal ArticleDOI
Maternal Control of Embryogenesis by MEDEA, a Polycomb Group Gene in Arabidopsis
TL;DR: The gametophytic maternal effect mutant medea (mea) shows aberrant growth regulation during embryogenesis in Arabidopsis thaliana, consistent with the parental conflict theory for the evolution of parent-of-origin-specific effects.
Journal ArticleDOI
The Arabidopsis Somatic Embryogenesis Receptor Kinase 1 Gene Is Expressed in Developing Ovules and Embryos and Enhances Embryogenic Competence in Culture
Valérie Hecht,Jean-Philippe Vielle-Calzada,Marijke Hartog,Eduard Daniel Leendert Schmidt,K. Boutilier,Ueli Grossniklaus,Ueli Grossniklaus,S. de Vries +7 more
TL;DR: An increased AtSERK1 level is sufficient to confer embryogenic competence in culture and demonstrate its role during establishment of somatic embryogenesis in culture.
Journal ArticleDOI
Control of female gamete formation by a small RNA pathway in Arabidopsis
Vianey Olmedo-Monfil,Noé V. Durán-Figueroa,Mario A. Arteaga-Vazquez,Mario A. Arteaga-Vazquez,Edgar Demesa-Arevalo,Daphné Autran,Daniel Grimanelli,R. Keith Slotkin,R. Keith Slotkin,Robert A. Martienssen,Jean-Philippe Vielle-Calzada +10 more
TL;DR: The results show that AGO9-dependent sRNA silencing is crucial to specify cell fate in the Arabidopsis ovule, and that epigenetic reprogramming in companion cells is necessary for sRNA–dependent silencing in plant gametes.
Journal ArticleDOI
Maintenance of genomic imprinting at the Arabidopsis medea locus requires zygotic DDM1 activity
Jean-Philippe Vielle-Calzada,Julie Thomas,Charles Spillane,Alison Coluccio,Marilu A. Hoeppner,Ueli Grossniklaus +5 more
TL;DR: The results indicate that the maintenance of the genomic imprint at the mea locus requires zygotic DDM1 activity, and chromatin structure is likely to be interrelated with genomic imprinting in Arabidopsis.
Journal ArticleDOI
Delayed activation of the paternal genome during seed development
Jean-Philippe Vielle-Calzada,Ramamurthy Baskar,Ramamurthy Baskar,Ueli Grossniklaus,Ueli Grossniklaus +4 more
TL;DR: It is shown that none of the paternally inherited alleles of 20 loci that the authors tested is expressed during early seed development in Arabidopsis, contrary to previous interpretations, early embryo and endosperm development are mainly under maternal control.
