Journal ArticleDOI
The Polycomb-group protein MEDEA regulates seed development by controlling expression of the MADS-box gene PHERES1.
Claudia Köhler,Lars Hennig,Charles Spillane,Stéphane Pien,Wilhelm Gruissem,Ueli Grossniklaus +5 more
TL;DR: The results demonstrate that seed abortion in the medea mutant is largely mediated by deregulated expression of the type I MADS-box gene PHE1, consistent with the proposed function of the FIS genes as transcriptional repressors.
Journal ArticleDOI
Arabidopsis MSI1 is a component of the MEA/FIE Polycomb group complex and required for seed development
Claudia Köhler,Lars Hennig,Romaric Bouveret,Jacqueline Gheyselinck,Ueli Grossniklaus,Wilhelm Gruissem +5 more
TL;DR: It is established that msi1 mutant gametophytes initiate endosperm development in the absence of fertilization at a high penetrance and that MSI1 has an essential function in the correct initiation and progression of seed development.
Journal ArticleDOI
HLM1, an Essential Signaling Component in the Hypersensitive Response, Is a Member of the Cyclic Nucleotide–Gated Channel Ion Channel Family
Claudine Balagué,Baiqing Lin,Carine Alcon,Guylaine Flottes,Susanna Malmström,Claudia Köhler,Gunther Neuhaus,Georges Pelletier,Frédéric Gaymard,Dominique Roby +9 more
TL;DR: A novel mutation in Arabidopsis, hlm1, which causes aberrant regulation of cell death, manifested by a lesion-mimic phenotype and an altered HR, segregated as a single recessive allele exhibited increased resistance to a virulent strain of Pseudomonas syringae pv tomato.
Journal ArticleDOI
The Arabidopsis thaliana MEDEA Polycomb group protein controls expression of PHERES1 by parental imprinting
TL;DR: The maternally expressed Arabidopsis thaliana Polycomb group protein MEDEA (MEA) controls expression of the MADS-box gene PHE1, and it is shown that this maternal repression ofPHE1 breaks down in seeds lacking maternal MEA activity.
Journal ArticleDOI
Different Polycomb group complexes regulate common target genes in Arabidopsis.
Grigory Makarevich,Grigory Makarevich,Olivier Leroy,Olivier Leroy,Umut Akinci,Daniel Schubert,Oliver Clarenz,Justin Goodrich,Ueli Grossniklaus,Claudia Köhler,Claudia Köhler +10 more
TL;DR: It is proposed that different PcG complexes regulate a common set of target genes during the different stages of plant development.
