Metaphase Configurations in Drosophila: A Comparison of Endemic Hawaiian Species and Non-Endemic Species [PDF]

, 1976
The metaphase configurations of 400 strains from 63 species of Hawaiian Drosophila were determined from squash preparations of larval brain tissue or spermatogenic cells from adult testes.

PWO proteins are associated with PRC2 since their emergence in vascular plants

New Phytologist, EarlyView.
Summary The Polycomb repressive complex 2 (PRC2), a conserved histone methyltransferase complex, plays a central role in transcriptional silencing across eukaryotes. Here, we investigate the evolution of PWWP‐DOMAIN INTERACTORS OF POLYCOMBS (PWOs), which interact with PRC2, and examine the conservation of the PWOs‐PRC2 interaction across plant ...

A Natural LTR Retrotransposon Insertion in the Promoter of GhNAC140‐Dt Boosts Cotton Lint Yield

Plant Biotechnology Journal, EarlyView.
ABSTRACT Transposable elements (TEs) are fundamental drivers of crop evolution and domestication. Whereas the underlying mechanisms of TE‐mediated gene activation remain poorly understood. Lint percentage is an important yield component in cotton. Here, we report a retrotransposon insertion in the promoter of GhNAC140‐Dt, a secondary wall NAC encoding ...

A stage‐dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean

Plant, Cell &Environment, EarlyView.
Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

CHAMP1 complex directs heterochromatin assembly and promotes homology-directed DNA repair

Nature Communications
The CHAMP1 complex, a little-known but highly conserved protein complex consisting of CHAMP1, POGZ, and HP1α, is enriched in heterochromatin though its cellular function in these regions of the genome remain unknown.

DNA Hypomethylation Is One of the Epigenetic Mechanisms Involved in Salt‐Stress Priming in Soybean Seedlings

Plant, Cell &Environment, EarlyView.
ABSTRACT Salt‐stress priming enhances the tolerance of plants against subsequent exposure to a similar stress. Priming‐induced transcriptomic reprogramming is mediated by multiple epigenetic mechanisms, the best known of which is histone modifications. However, not much is known about other epigenetic responses.

A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

Experimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this

Reorganization of H3K9me heterochromatin leads to neuronal impairment via the cascading destruction of the KDM3B-centered epigenomic network

iScience
Summary: Histone H3K9 methylated heterochromatin silences repetitive non-coding sequences and lineage-specific genes during development, but how tissue-specific genes escape from heterochromatin in differentiated cells is unclear.

Senolytics and exercise: Dual modalities for rejuvenating muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

Technologies for engineering repetitive DNA

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.
