Imprinting

Imprinting

Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Summary

Genomic imprinting, where genes are expressed unequally from parents, is observed in the liverwort Marchantia polymorpha. The paternal genome is repressed by H3K27me3, an epigenetic mark reset during meiosis.

Background:

Genomic imprinting is an epigenetic phenomenon where parental genomes are expressed unequally.
Recent studies reveal paternal genome repression in the liverwort Marchantia polymorpha during its diploid phase.

Purpose of the Study:

To analyze genomic imprinting in Marchantia polymorpha.
To discuss imprinting mechanisms and evolutionary causes in bryophytes.

Main Methods:

Epigenetic mark analysis (H3K27me3 deposition).
Life cycle stage analysis (diploid phase, meiosis).

Main Results:

The entire paternal genome is repressed in Marchantia polymorpha.
H3K27me3 is deposited on the male pronucleus, causing imprinting.
Imprinted state is reset by the end of meiosis.

Conclusions:

Paternal genome repression via H3K27me3 is a key feature of imprinting in Marchantia polymorpha.
Understanding imprinting in bryophytes offers insights into its evolution and mechanisms.
