The grass seed or caryopsis originates from a monocarpellary ovary with a single ovule and
contains the main storage tissue, the endosperm. For most grass crop species (ie cereals) …

Genomic imprinting results in monoallelic gene expression in a parent-of-origin–dependent
manner. It is achieved by the differential epigenetic marking of parental alleles. Over the past …

DNA methylation is known to play an important role in the regulation of gene expression in
eukaryotes. In this study, we assessed the extent and pattern of cytosine methylation in the …

Allopolyploid formation requires the adaptation of two nuclear genomes within a single
cytoplasm, which may involve programmed genetic and epigenetic changes during the …

In higher plants, seed development requires maternal gene activity in the haploid
(gametophytic) as well as diploid (sporophytic) tissues of the developing ovule. The …

Growth of the maize (Zea mays) endosperm is tightly regulated by maternal zygotic and
sporophytic genes, some of which are subject to a parent-of-origin effect. We report here a …

DNA methylation is known to play an important role in the regulation of gene expression in
eukaryotes. In this study, we assessed the extent and pattern of cytosine methylation during …

Winter dormancy is a well known mechanism adopted by temperate plants, to mitigate the
chilling temperature of winters. However, acquisition of sufficient chilling during winter …

DNA methylation in plants is related to a number of epigenetic (ie heritable, but potentially
reversible) phenomena. Heavy methylation of cytosine residues plays an important role in …

Background DNA demethylation occurs in many species and is involved in diverse
biological processes. However, the occurrence and role of DNA demethylation in maize …
