Genome-wide mapping and cryo-EM structural analyses of the overlapping tri-nucleosome composed of hexasome-hexasome-octasome moieties

open access: yesCommunications Biology
The nucleosome is a fundamental unit of chromatin in which about 150 base pairs of DNA are wrapped around a histone octamer. The overlapping di-nucleosome has been proposed as a product of chromatin remodeling around the transcription start site, and ...

Divergence of nucleosome positioning between two closely related yeast species: genetic basis and functional consequences

open access: yesMolecular Systems Biology, 2010
Gene regulation differs greatly between related species, constituting a major source of phenotypic diversity. Recent studies characterized extensive differences in the gene expression programs of closely related species. In contrast, virtually nothing is

Recovery From Anorexia Nervosa: A Concept Analysis

open access: yesJournal of Advanced Nursing, EarlyView.
ABSTRACT Aim Despite decades of research, we still know surprisingly little about how best to bring about lasting recovery from anorexia nervosa (AN). Furthermore, there is a lack of consensus in the research and treatment communities about what constitutes recovery from AN, or whether “recovery” is even an appropriate term to use in this context.

Transcriptional adapter ADA2 regulates yield and end‐use quality through liquid–liquid phase separation in wheat

open access: yesJournal of Integrative Plant Biology, EarlyView.
The transcriptional adapter ADA2 interacts with the histone acetyltransferase GCN5 to regulate starch and storage protein content in wheat grains through histone acetylation. ADA2 undergoes phase separation and is modulated by GCN5, affecting histone acetyltransferase activity and gene transcription.

Epigenetic Regulation in the Pathogenesis of Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
The aim of this narrative literature review was to identify epigenetic marks associated with periodontitis and to place them in a biological context. The literature was reviewed based on pre‐defined criteria. Cell type specific chromatin and mRNA modifications were included.

Epigenetic regulation of mycorrhizal symbioses: from plastic responses to transgenerational legacies

open access: yesNew Phytologist, EarlyView.
Summary Mycorrhizal symbioses represent one of the most widespread and ecologically significant plant–microbe interactions, shaping plant nutrition, stress resilience, and ecosystem functioning. Beyond their role in nutrient exchange and systemic defense, growing evidence suggests that these symbioses also influence plant plasticity within and across ...

Fascinating single‐cell red algae: models for evolution and adaptation

open access: yesNew Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Single‐Cell CRISPR: An Efficient Strategy for Decoding Plant Cis‐Regulatory Complexity

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The generation of complex traits involves the coordinated interplay of multiple gene networks. Elucidating the function of transcriptional cis‐regulatory elements (CREs) in regulating gene expression is crucial for understanding complex regulatory pathways and improving our ability to modify macro‐phenotypes.

Nucleosomes and Cisplatin

open access: yesChemistry & Biology, 2010
In order to form a covalent complex with DNA inside human cells, cisplatin has to overcome the protective environment of a nucleosome, where DNA is complexed with histone proteins. Todd and Lippard (2010) expand our understanding of this process by describing the structure of a nucleosome containing a Pt-DNA adduct, which has important implications for
