title: [Parental genomic imprinting in plants: significance for reproduction].
abstract: Parental genomic imprinting is an epigenetic phenomenon causing the expression of a gene from one of the two parental alleles. Imprinting has been identified in plants and mammals. Recent evidence shows that DNA methylation and histone modifications are responsible for this parent-of-origin dependent expression of imprinted genes. We review the mechanisms and functions of imprinting in plants. We further describe the significance of imprinting for reproduction and discuss potential models for its evolution.
