Brazilian Journal of BiologyThe 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 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 ...

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.

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.

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.

Seipin deficiency increases chromocenter fragmentation and disrupts acrosome formation leading to male infertility [PDF]
Cell Death & Disease, 2015 AbstractThe Berardinelli–Seip congenital lipodystrophy type 2 (Bscl2, seipin) gene is involved in adipogenesis. Bscl2−/− males were infertile but had normal mating behavior. Both Bscl2−/− cauda epididymis sperm count and sperm motility were ~20 × less than control.

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.

Cytogenetic study on Artemia from Urmiyah lake
Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2001 To determine the chromosome numbers of artemia brine-shrimp in Urmiyah Lake (Azarbaijan-e- Gharhi province), cytogenetic studies were carried out on artemia cysts.

Relationship of chromocenter number, size, and density to plant biomass
Caryologia, 1996 SUMMARYA variety of plant species and cultivars were stained for chromocenters using the barium hydroxide, sodium saline citrate (SSC), Giemsa procedure (DNA denaturation, incubation-renaturation, staining), in order to test the hypothesis that larger (biomass) species have larger, more numerous, and more intensely-staining chromocenters.
