Characterization of radiations‐induced genomic structural variations in Arabidopsis thaliana

The Plant Journal, Volume 121, Issue 1, January 2025.
Significance Statement Exposure to genotoxic stress activates DNA damage response (DDR) and challenges genome integrity. Using third generation sequencing technology, we characterized alterations of the linear genome structure of Arabidopsis plants treated with non‐ionizing (UV‐B, UV‐C) and ionizing radiations (protons). We identified, in wild type and

Diurnal control of H3K27me1 deposition shapes expression of a subset of cell cycle and DNA damage response genes

The Plant Journal, Volume 120, Issue 6, Page 2325-2336, December 2024.
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

Variation of the interphase heterochromatin in Artemia (Crustacea, Anostraca) of the Americas is related to changes in nuclear size and ionic composition of hipersaline habitats

Brazilian Journal of Biology
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 ...

The histone chaperones ASF1 and HIRA are required for telomere length and 45S rDNA copy number homeostasis

The Plant Journal, Volume 120, Issue 3, Page 1125-1141, November 2024.
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 ...

Ectopic expression of Kip-related proteins restrains root-knot nematode-feeding site expansion [PDF]

, 2013
The development of nematode feeding sites induced by root-knot nematodes involves the synchronized activation of cell cycle processes such as acytokinetic mitoses and DNA amplification.

Hop stunt viroid infection induces heterochromatin reorganization

New Phytologist, Volume 243, Issue 6, Page 2351-2367, September 2024.
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.

Photodamage repair pathways contribute to the accurate maintenance of the DNA methylome landscape upon UV exposure.

PLoS Genetics, 2019
Plants are exposed to the damaging effect of sunlight that induces DNA photolesions. In order to maintain genome integrity, specific DNA repair pathways are mobilized.

HHV-8 encoded LANA-1 alters the higher organization of the cell nucleus

Molecular Cancer, 2007
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.
