Imprinting and seed development.
Imprinted genes are expressed predominantly from one allele in a parent-of-origin–specific manner. The endosperm, a seed tissue that mediates the transfer of nutrients from the maternal parent to the embryo, is an important site of imprinting in flowering plants. Imprinted genes have been identified in maize and Arabidopsis thaliana, but crosses in a variety of species suggest that the effect o...
متن کاملRegulation and Flexibility of Genomic Imprinting during Seed Development W
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 decade, studies in the model systems Arabidopsis thaliana and maize (Zea mays) have shown a strong correlation between silent or active states with epigenetic marks, such as DNA methylation and histone modifica...

متن کاملlgf2 imprinting 145 Igf2 imprinting in development and disease
Igf2 is one of the first imprinted genes discovered and occupies a centre stage in the study of imprinting. This is because it has dramatic effects on the control of fetal growth, it is involved in growth disorders and in cancer, it interacts with products of other imprinted genes, and its imprinting status is under complex regulation in a cluster of tightly linked imprinted genes. Here we revi...
