Cytogenetics and cytotaxonomy of some Brazilian species of Cymbidioid orchids
The Cymbidioid phylad presents the widest chromosome number variation among orchids, with records varying from 2n = 10 in Psygmorchis pusilla to 2n = 168 in two species of Oncidium.

Fruit Flies Provide New Insights in Low-Radiation Background Biology at the INFN Underground Gran Sasso National Laboratory (LNGS) [PDF]
Deep underground laboratories (DULs) were originally created to host particle, astroparticle or nuclear physics experiments requiring a low-background environment with vastly reduced levels of cosmic-ray particle interference. More recently, the range of

ATRX: From Chromatin Remodeling to Disease
ABSTRACT Chromatin remodeling proteins are evolutionarily conserved factors involved in a wide range of biological processes. In this review, we describe ATRX, a chromatin remodeling protein belonging to the SWI/SNF2 family. Its association with different protein complexes, and its roles in embryonic development, sexual differentiation, as well as ...

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 -

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

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.

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 ...

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.

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.
