Human Bone Marrow Mesenchymal Stem Cells Regulate Biased DNA Segregation in Response to Cell Adhesion Asymmetry

Cell Reports, 2013
Biased DNA segregation is a mitotic event in which the chromatids carrying the original template DNA strands and those carrying the template copies are not segregated randomly into the two daughter cells.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

A novel, PCP‐dependent tissue organising principle coordinating morphogenesis between embryonic skin epidermal layers

Journal of Anatomy, EarlyView.
‘Outside‐in’ expression of Fz6 across multiple layers of mouse embryo epidermis is connected to Fz6 asymmetry in the basal layer plane. Fz6 loss‐of‐function correlated with failure to: coordinate axial bias of cell long axis orientation across epidermal layers, switch axial cell long axis orientation during suprabasal layer development and establish ...

Supernumerary B chromosomes of Aegilops speltoides undergo precise elimination in roots early in embryo development

Nature Communications, 2020
B chromosomes are supernumerary chromosomes exhibiting dramatic differences between different organs in same species. Here, the authors show programmed B chromosome elimination in goatgrass starts at the onset of embryo differentiation by nondisjunction ...

The Rhus chinensis Genome Provides Insights Into Tannin, Flavonoid Biosynthesis, and Glandular Trichome Development

Plant Biotechnology Journal, EarlyView.
ABSTRACT The “salt tree”, Rhus chinensis, holds significant economic and medicinal value due to its ability to produce Galla chinensis (Chinese gall/gallnut), a plant‐derived medicinal material used in both traditional Chinese and modern medicine that is rich in tannins and flavonoids. It is also renowned for its remarkable stress tolerance.

Myosin efflux promotes cell elongation to coordinate chromosome segregation with cell cleavage

Nature Communications, 2017
Chromatid segregation must be coordinated with cytokinesis to preserve genomic stability. Here the authors show that cells clear trailing chromatids from the cleavage site in a two-step cell elongation and demonstrate the role of myosin efflux in the ...

Cell‐Type‐Specific and Variety‐Specific Responses to Salt Stress in Wheat Root Revealed by Single‐Cell Transcriptomics

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinization threatens the yield and quality of wheat. Roots are critical for the salt stress response, yet their cell‐type‐specific mechanisms remain unclear. We conducted the first single‐nucleus RNA sequencing analysis of wheat root tips from salt‐sensitive (CS) and ‐tolerant (DK) varieties under salt stress, profiling 188 270 high ...

Induction of Synthetic Apomixis in Two Sorghum Hybrids Enables Seed Yield and Genotype Preservation Over Multiple Generations

Plant Biotechnology Journal, EarlyView.
ABSTRACT Induction of apomixis, or clonal reproduction through seed, could economise commercial hybrid seed production and enable smallholder farmers to save and sow hybrid seed. Here, we demonstrate the synthetic induction of apomixis in two sorghum hybrids and show that the clonal hybrid seed can be maintained across multiple seed generations.

The PagDMG6341–PagWD40–PagPOLD4 Module Coordinates Base Excision Repair in ‘84K’ Poplar (Populus alba × P. glandulosa)

Plant Biotechnology Journal, EarlyView.
ABSTRACT Base excision repair (BER) is a critical pathway for repairing damaged DNA bases in cells; however, the mechanisms of protein recruitment and interaction in this pathway remain largely unexplored in higher plants. In this study, we used ‘84K’ poplar (Populus alba × P.

An In Vitro and In Vivo Assessment of the Genotoxic Potential of Maizinol (UP165), a Zea mays Leaf Extract

Journal of Applied Toxicology, Volume 46, Issue 3, Page 950-960, March 2026.
ABSTRACT Benzoxazinoids are secondary metabolites produced in monocotyledons and some dicotyledons from the Acanthaceae, Ranunculaceae, Scrophulariaceae, Plantaginaceae, and Lamiaceae families. Benzoxazinoids are commonly consumed in bread and cereal products that have been ingested for decades, which supports the safe use of benzoxazinoids as food ...
