Bookmarking Target Genes in Mitosis: A Shared

... role in bookmarking genes during mitosis has been well studied (1). Additional evidence for a role of histone modifications in mitotic gene bookmarking is suggested by observations at the level of a higher-order chromosome architecture (35). In this study, Terrenoire and colleagues have found a strik ...

In 1790, Johann Wolfgang von Goethe published his seminal essay Metamorphosis of Plants in which he proposed that the above-ground organs of a plant are derived (‘metamorphosed’) from leaves (von Goethe, 1790).

Genomic imprinting

Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed. If the allele from the mother is imprinted, then only the allele from the father is expressed. Forms of genomic imprinting have been demonstrated in fungi, plants and animals. Genomic imprinting is a fairly rare phenomenon in mammals; most genes are not imprinted.In insects, imprinting affects entire chromosomes. In some insects the entire paternal genome is silenced in male offspring, and thus is involved in sex determination. The imprinting produces effects similar to the mechanisms in other insects that eliminate paternally inherited chromosomes in male offspring, including arrhenotoky.Genomic imprinting is an inheritance process independent of the classical Mendelian inheritance. It is an epigenetic process that involves DNA methylation and histone methylation without altering the genetic sequence. These epigenetic marks are established (""imprinted"") in the germline (sperm or egg cells) of the parents and are maintained through mitotic cell divisions in the somatic cells of an organism.Appropriate imprinting of certain genes is important for normal development. Human diseases involving genomic imprinting include Angelman syndrome and Prader–Willi syndrome.
