Journal ArticleDOI
DEMETER, a DNA Glycosylase Domain Protein, Is Required for Endosperm Gene Imprinting and Seed Viability in Arabidopsis
Yeonhee Choi,Mary Gehring,Lianna M. Johnson,Mike Hannon,John J. Harada,Robert B. Goldberg,Steven E. Jacobsen,Robert L. Fischer +7 more
TL;DR: The authors isolated mutations in Arabidopsis to understand how the female gametophyte controls embryo and endosperm development and identified the DEMETER (DME) gene, which is required for maternal allele expression of the imprinted MEDEA (MEA) Polycomb gene in the central cell andendosperm.
Journal ArticleDOI
DEMETER DNA Glycosylase Establishes MEDEA Polycomb Gene Self-Imprinting by Allele-Specific Demethylation
Mary Gehring,Jin Hoe Huh,Tzung-Fu Hsieh,Jon Penterman,Yeonhee Choi,John J. Harada,Robert B. Goldberg,Robert L. Fischer +7 more
TL;DR: DME is responsible for endosperm maternal-allele-specific hypomethylation at the MEA gene, which establishes MEA imprinting by removing 5-methylcytosine to activate the maternal allele and is subsequently maintained in theendosperm by maternal MEA silencing the paternal allele.
Journal ArticleDOI
One-way control of FWA imprinting in Arabidopsis endosperm by DNA methylation.
Tetsu Kinoshita,Asuka Miura,Yeonhee Choi,Yuki Kinoshita,Xiaofeng Cao,Steven E. Jacobsen,Robert L. Fischer,Tetsuji Kakutani +7 more
TL;DR: It is shown that wild-type FWA displays imprinted (maternal origin–specific) expression in endosperm, which enables plants to use such “one-way” control of imprinting and DNA methylation inendosperm.
Journal ArticleDOI
Mutations in the FIE and MEA Genes That Encode Interacting Polycomb Proteins Cause Parent-of-Origin Effects on Seed Development by Distinct Mechanisms
Ramin Yadegari,Tetsu Kinoshita,Ofra Lotan,Gal Cohen,Anat Katz,Yeonhee Choi,Aviva Katz,Kazuo Nakashima,John J. Harada,Robert B. Goldberg,Robert L. Fischer,Nir Ohad +11 more
TL;DR: It is shown that FIE and MEA polycomb proteins interact physically, suggesting that the molecular partnership of WD and SET domainpolycomb proteins has been conserved during the evolution of flowering plants.
Journal ArticleDOI
Imprinting of the MEA Polycomb Gene Is Controlled by Antagonism between MET1 Methyltransferase and DME Glycosylase
Wenyan Xiao,Mary Gehring,Yeonhee Choi,Linda Margossian,Hong Pu,John J. Harada,Robert B. Goldberg,Roger I. Pennell,Robert L. Fischer +8 more
TL;DR: The data suggest that imprinting is controlled in the female gametophyte by antagonism between the two DNA-modifying enzymes, MET1 methyltransferase and DME DNA glycosylase.
