The populations of Artemia (or brine shrimp) from the Americas exhibit a wide variation in the amount of interphase heterochromatin. There is interest in understanding how this variation affects different parameters, from the cellular to the organismal ...

Significance Statement We ask here how diurnal changes impact chromatin modifications and gene expression. We have found that H3K27me1 is preferentially deposited during the night along the bodies of cell cycle and DNA damage response genes. Our study highlights the relevance of the diurnal control of the chromatin landscape of genes involved in genome

Significance Statement The H3 histone chaperones ANTI‐SILENCING FUNCTION 1 (ASF1) and HISTONE REGULATOR A (HIRA) are crucial for telomere length homeostasis, 45S rRNA gene silencing, and determination of 45S rDNA copy number. ASF1 affects heterochromatin organization, and its function is linked to the telomere protective complex through possible ...

Cytogenetic study on Artemia from Urmiyah lake
To determine the chromosome numbers of artemia brine-shrimp in Urmiyah Lake (Azarbaijan-e- Gharhi province), cytogenetic studies were carried out on artemia cysts.

HHV-8 encoded LANA-1 alters the higher organization of the cell nucleus
The latency-associated nuclear antigen (LANA-1) of Human Herpes Virus 8 (HHV-8), alternatively called Kaposi Sarcoma Herpes Virus (KSHV) is constitutively expressed in all HHV-8 infected cells.

Hop stunt viroid infection induces heterochromatin reorganization
Summary Viroids are pathogenic noncoding RNAs that completely rely on their host molecular machinery to accomplish their life cycle. Several interactions between viroids and their host molecular machinery have been identified, including interference with epigenetic mechanisms such as DNA methylation.

Light control of three‐dimensional chromatin organization in soybean
Summary Higher‐order chromatin structure is critical for regulation of gene expression. In plants, light profoundly affects the morphogenesis of emerging seedlings as well as global gene expression to ensure optimal adaptation to environmental conditions.

SUMMARY DNA–protein crosslinks (DPCs) are highly toxic DNA lesions represented by proteins covalently bound to the DNA. Persisting DPCs interfere with fundamental genetic processes such as DNA replication and transcription. Cytidine analog zebularine (ZEB) has been shown to crosslink DNA METHYLTRANSFERASE1 (MET1). Recently, we uncovered a critical role
