ABSTRACT In ungulates, the development of the trophoblast lineage follows a peculiar process, as implantation is preceded by a relatively long period of trophoblast elongation, the molecular control of which is still not well known. Here, we have established novel bovine trophoblast stem cells (b2iTSCs) growing in a completely defined medium containing

SCaMC-1 like a member of the mitochondrial carrier (MC) family preferentially expressed in testis and localized in mitochondria and chromatoid body [PDF]
Mitochondrial carriers (MC) form a highly conserved family involved in solute transport across the inner mitochondrial membrane in eukaryotes. In mammals, ATP-Mg/Pi carriers, SCaMCs, form the most complex subgroup with four paralogs, SCaMC-1, -2, -3 and -

Pericentromeric heterochromatin is hierarchically organized and spatially contacts H3K9me2 islands in euchromatin. [PDF]
Membraneless pericentromeric heterochromatin (PCH) domains play vital roles in chromosome dynamics and genome stability. However, our current understanding of 3D genome organization does not include PCH domains because of technical challenges associated ...

Aggregation of the Constitutively Active K296E Rhodopsin Mutant Contributes to Retinal Degeneration
The K296E rhodopsin mutation causes autosomal dominant retinitis pigmentosa. The pathogenic effect of the mutation has typically been attributed to effects related to the constitutive activity detected in the mutant in some studies. We demonstrate here that the K296E rhodopsin mutant aggregates.

Phase Separation: A New Dimension to Understanding Tumor Biology and Therapy
Liquid–liquid phase separation (LLPS) facilitates the assembly of biomolecular condensates by leveraging weak multivalent interactions. The low‐complexity domains, foldable domains of proteins, and nucleic acids provide multivalent interaction sites among different molecules and contribute to the formation of condensates.

Nuclear fusions contribute to polyploidization of the gigantic nuclei in the chalazal endosperm of Arabidopsis [PDF]
Somatic polyploidization is recognized as a means to increase gene expression levels in highly active metabolic cells. The most common mechanisms are endoreplication, endomitosis and cell fusion.

Chromatin Topological Domains Associate With the Rapid Formation of Tandem Duplicates in Plants
A collection of Hi‐C matrices across the plant kingdom confirms the interrelation between large‐scale chromosome conformation and species genome size. At a finer level, tandem duplicate gene clusters preferentially fold into topologically associating domains (TADs) in an evolutionarily conserved manner.

Characterization of radiations‐induced genomic structural variations in Arabidopsis thaliana
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

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
