Developmentally regulated expression of a cyclic nucleotide-gated ion channel from Arabidopsis indicates its involvement in programmed cell deathC Kohler
Institut fur Botanik, Zurich, Switzerland
Planta 213:327-32. 2001..Furthermore, expression of AtCNGC2 was transiently induced during leaf and cell culture senescence. These results indicate a potential function for AtCNGC2 in the initiation of developmentally regulated cell death programs...

Institute of Plant Biology, University of Zurich, Zollikerstrasse 107, CH 8008, Zurich, Switzerland
Curr Biol 12:R129-31. 2002..Recent findings shed light on this phenomenon by showing that a gene responsible for keeping this memory encodes a member of the Polycomb group of proteins...
Epigenetic inheritance of expression states in plant development: the role of Polycomb group proteinsClaudia Kohler
Institute of Plant Biology, University of Zurich, Zollikerstrasse 107, CH 8008, Zurich, Switzerland
Curr Opin Cell Biol 14:773-9. 2002..This may be related to the absence of PcG proteins thought to be involved in long-term maintenance of PcG repression, suggesting that the mechanisms underlying PcG-mediated repression differ between plants and animals...
The Polycomb-group protein MEDEA regulates seed development by controlling expression of the MADS-box gene PHERES1Claudia Kohler
Institute of Plant Biology and Zurich Basel Plant Science Center, University of Zurich, Ch 8008 Zurich, Switzerland
Genes Dev 17:1540-53. 2003..In summary, our results demonstrate that seed abortion in the medea mutant is largely mediated by deregulated expression of the type I MADS-box gene PHE1...
The Arabidopsis thaliana MEDEA Polycomb group protein controls expression of PHERES1 by parental imprintingClaudia Kohler
Institute of Plant Biology and Zurich Basel Plant Science Center, University of Zurich, Zollikerstrasse 107, Ch 8008 Zurich, Switzerland
Nat Genet 37:28-30. 2005..Because Polycomb group proteins control parental imprinting in mammals as well, the independent recruitment of similar protein machineries for the imprinting of genes is a notable example of convergent evolution...
Imprinting of the polycomb group gene MEDEA serves as a ploidy sensor in ArabidopsisAleksandra Erilova
Department of Biology and Zurich Basel Plant Science Center, Swiss Federal Institute of Technology, Zurich, Switzerland
PLoS Genet 5:e1000663. 2009..We propose that imprinted expression of PcG genes is an evolutionary conserved mechanism to balance parental genome contributions in embryo nourishing tissues...
The chromodomain of LIKE HETEROCHROMATIN PROTEIN 1 is essential for H3K27me3 binding and function during Arabidopsis developmentVivien Exner
Department of Biology and Zurich Basel Plant Science Center, ETH Zurich, Zurich, Switzerland
PLoS ONE 4:e5335. 2009..Therefore, binding to H3K27me3 is essential for LHP1 protein function...
Seed development and genomic imprinting in plantsClaudia Kohler
Institute of Plant Biology and Zurich Basel Plant Science Center, University of Zurich, Zollikerstrasse 107, 8008 Zurich, Switzerland
Prog Mol Subcell Biol 38:237-62. 2005..Thus, although imprinting evolved independently in mammals and plants, there are striking similarities at the phenotypic and possibly also mechanistic level...
Antagonizing Polycomb group-mediated gene repression by chromatin remodelersClaudia Kohler
Department of Biology and Zurich Basel Plant Science Center, Swiss Federal Institute of Technology, ETH Centre, Zurich, Switzerland
Epigenetics 5:20-3. 2010..Here we will discuss the implications of these findings that point towards an evolutionary conservation of PcG/trxG mediated gene regulation in higher eukaryotes...
High-resolution analysis of parent-of-origin allelic expression in the Arabidopsis EndospermPhilip Wolff
Department of Biology and Zurich Basel Plant Science Center, Swiss Federal Institute of Technology, Zurich, Switzerland
PLoS Genet 7:e1002126. 2011....
Genetic interaction of an origin recognition complex subunit and the Polycomb group gene MEDEA during seed developmentMargaret A Collinge
Institute of Plant Biology, University of Zurich, 8008 Zurich, Switzerland
Plant Cell 16:1035-46. 2004..Either alterations in chromatin structure or the release of cell cycle checkpoints by the mea mutation may allow more cell and nuclear divisions to occur in orc2 homozygous seeds...
Arabidopsis MSI1 is a component of the MEA/FIE Polycomb group complex and required for seed developmentClaudia Kohler
Institute of Plant Biology and Zurich Basel Plant Science Centre, University of Zurich, Zollikerstrasse 107, CH 8050 Zurich, Switzerland
EMBO J 22:4804-14. 2003..Our results establish that MSI1 has an essential function in the correct initiation and progression of seed development...
CHD3 proteins and polycomb group proteins antagonistically determine cell identity in ArabidopsisErnst Aichinger
Department of Biology and Zurich Basel Plant Science Center, Swiss Federal Institute of Technology, ETH Centre, Zurich, Switzerland
PLoS Genet 5:e1000605. 2009..Thus, in contrast to mammals, where PcG proteins are required to maintain pluripotency and to prevent cell differentiation, in plants PcG proteins are required to promote cell differentiation by suppressing embryonic development...
Bisulphite sequencing of plant genomic DNAErnst Aichinger
Department of Biology, Swiss Federal Institute of Technology ETH, Zurich, Switzerland
Methods Mol Biol 655:433-43. 2010..Here, a detailed protocol for bisulphite conversion, primer design, and optimization of PCR conditions is given. Specific requirements for plant DNA are discussed...

Department of Biology and Zurich Basel Plant Science Center, Swiss Federal Institute of Technology, ETH Centre, Zurich, Switzerland
J Exp Bot 62:1659-68. 2011..The potential to use the knowledge gained from Arabidopsis mutants to design tools and develop techniques to engineer unreduced gamete production in important crop species for use in plant breeding is also discussed...
