Compromised stability of DNA methylation and transposon immobilization in mosaic Arabidopsis epigenomes
Jon Reinders,Brande B. H. Wulff,Marie Mirouze,Arturo Marí-Ordóñez,Mélanie Dapp,Wilfried Rozhon,Etienne Bucher,Grégory Theiler,Jerzy Paszkowski +8 more
TL;DR: Although analysis after eight generations of inbreeding, supported by genome-wide DNA methylation profiling, identified recombined parental chromosomal segments, these were interspersed with unexpectedly high frequencies of nonparental methylation polymorphism, which complicate linkage-based epigenomic mapping.
DNA sequence properties that predict susceptibility to epiallelic switching
Marco Catoni,Jayne Griffiths,Claude Becker,Nicolae Radu Zabet,Carlos Bayon,Mélanie Dapp,Michal Lieberman-Lazarovich,Detlef Weigel,Jerzy Paszkowski +8 more
TL;DR: Examination of genome-wide DNA methylation in partial and complete loss-of-function met1 mutants provides evidence that DNA sequence features such as density of CpGs and genomic repetitiveness can be used to predict susceptibility to epiallelic switching.

Heterosis and inbreeding depression of epigenetic Arabidopsis hybrids
Mélanie Dapp,Jon Reinders,Alexis Bédiée,Crispulo Balsera,Etienne Bucher,Grégory Theiler,Christine Granier,Jerzy Paszkowski,Jerzy Paszkowski +8 more
TL;DR: The results strongly suggest that epigenetic diversity and epigenetic regulation of transcription play a role in hybrid vigour and inbreeding depression, and also in the absence of parental genetic diversity.
DNA sequence properties that predict susceptibility to epiallelic switching
Marco Catoni,Jayne Griffiths,Claude Becker,Nicolae Radu Zabet,Carlos Bayon,Mélanie Dapp,Michal Lieberman-Lazarovich,Detlef Weigel,Jerzy Paszkowski,Jerzy Paszkowski +9 more
TL;DR: Evidence that DNA sequence features such as density of CpGs and genomic repetitiveness of the loci predispose their susceptibility to epiallelic switching is provided, confirming the importance and predictive power of these genetic features.
Phenotyping the kinematics of leaf development in flowering plants: recommendations and pitfalls
Maryline Lièvre,Nathalie Wuyts,Sarah Jane Cookson,Justine Bresson,Mélanie Dapp,François Vasseur,Catherine Massonnet,Sébastien Tisné,Mathilde Bettembourg,Crispulo Balsera,Alexis Bédiée,Frédéric Bouvery,Myriam Dauzat,Gaëlle Rolland,Denis Vile,Christine Granier +15 more
TL;DR: Concrete examples presented here indicate that simplification of the dynamic leaf system, without consideration of its spatial and temporal context, can lead to important misinterpretations of the growth phenotype.
