Light control of three‐dimensional chromatin organization in soybean

Plant Biotechnology Journal, Volume 22, Issue 9, Page 2596-2611, September 2024.
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.

Spatial point patterns within the nucleus and distance functions.

, 2013
Centromere/chromocenter positions are represented as dots within nuclear contours. (A) Various types of spatial distribution. Positions can be uniformly and independently distributed (completely random pattern), or exhibit mutual attraction (aggregated ...

Sexual dimorphism in somatic interphase nuclei of snakes

, 1970
Somatic interphase nuclei of different tissues of heterogametic females of various species of snakes with a differentiated W chromosome possess a distinct, darkly stained chromocenter comparable to the characteristic mammalian sex chromatin.

Structure and Arrangement of Salivary Gland Chromosomes in Drosophila Species [PDF]

, 1936
The salivary gland nuclei in Drosophila contain two different chromosome derivatives, the long chromosome strands which correspond to the euchromatic parts of prophase chromosomes, and the chromocenter which arises from the heterochromatic regions (Heitz

CHD5 is enriched in pericentromeric chromatin of round spermatids.

, 2014
(A, B) Spread nuclei of spermatids immunostained for CHD5 and counterstained with DAPI. An example of a round spermatid nucleus that is positive for CHD5 expression and displays the high intensity focus in the chromocenter is shown in A and such an ...

Distinguishing individual photobodies using Oligopaints reveals thermo-sensitive and -insensitive phytochrome B condensation at distinct subnuclear locations

Nature Communications
Photobodies (PBs) are membraneless subnuclear organelles that self-assemble via concentration-dependent liquid-liquid phase separation (LLPS) of the plant photoreceptor and thermosensor phytochrome B (PHYB).

Mutations in peo affect DNA replication in brain cell nuclei.

, 2015
(A) Analysis of EdU-treated brain cell nuclei reveal 3 gross incorporation patterns: S1 nuclei incorporate EdU in most of the nucleus but not in the DAPI stained chromocenter and are presumably in early S; S2 nuclei incorporate EdU in both the ...

The role of RNA in the maintenance of chromatin domains as revealed by antibody-mediated proximity labelling coupled to mass spectrometry

eLife
Eukaryotic chromatin is organized into functional domains, that are characterized by distinct proteomic compositions and specific nuclear positions. In contrast to cellular organelles surrounded by lipid membranes, the composition of distinct chromatin ...
