..., occasionally leading to formation of two embryos per seed. Furthermore, seed coat, and putatively also endosperm development, frequently initiated autonomously. Such induction of several features phenocopying distinct elements of apomixis by a single mutation is unusual and suggests that RH17 acts...

...Léna Beauzamy; Chloé Fourquin; Nelly Dubrulle; Yann Boursiac; Arezki Boudaoud; Gwyneth Ingram In Arabidopsis , rapid expansion of the coenocytic endosperm after fertilisation has been proposed to drive early seed growth, which is in turn constrained by the seed coat. This hypothesis implies...

.... However, genome-wide studies suggested other DNA methylation-dependent imprinting mechanisms. Here, we show that de novo RNA-directed DNA methylation (RdDM) regulates imprinting at specific loci expressed in endosperm. RdDM in somatic tissues is required to silence expression of the paternal allele...

...Elisabeth Hehenberger; David Kradolfer; Claudia Köhler The endosperm is a terminal seed tissue that is destined to support embryo development. In most angiosperms, the endosperm develops initially as a syncytium to facilitate rapid seed growth. The transition from the syncytial to the cellularized...

AtLIG1 expression is not imprinted and has a limited impact on imprinted gene expression. Genetic interaction analyses further...
