Induction of gynogenesis by heterogenous sperm and cold shock treatment in Epinephelus fuscoguttatus
Reproduction and Breeding, 2021 Gynogenesis is a chromosome set manipulation technique to accelerate inbred lines used for genomics analysis and genetic breeding. Groupers are hermaphroditic fish whereby they sexually mature as females and subsequently change sex to male. Production of

Caspase 2 in mitotic catastrophe: The terminator of aneuploid and tetraploid cells
Molecular & Cellular Oncology, 2017 Mitotic catastrophe is an oncosuppressive mechanism that targets cells experiencing defective mitoses via the activation of specific cell cycle checkpoints, regulated cell death pathways and/or cell senescence.

Ploidy analysis among Citrus mutants using leaf meristematic tissue
Journal of Horticultural Sciences, 2022 A promising method for preparing metaphase spread for counting the number of chromosomes from the emerging shoot tissue is described in this report. In the present study, we adopted enzymatic digestion of shoot tips to analyse the chromosome number. The

Nature Communications, 2023 Whole genome duplication (WGD) is a dramatic evolutionary event generating many new genes and which may play a role in survival through mass extinctions. Paddlefish and sturgeon are sister lineages that both show genomic evidence for ancient WGD.

Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate
Limnology and Oceanography, Volume 71, Issue 6, June 2026.Abstract Sexual reproduction is fundamental to the ecology and evolution of eukaryotes, yet its dynamics in microbial eukaryotes are often cryptic. Dinophysis are specialist mixotrophs that must balance prey capture, cell division, and sexual recombination during blooms, but relatively little is known about the occurrence and role of sex in their ...

TOP1α, UPF1, and TTG2 regulate seed size in a parental dosage-dependent manner.
PLoS Biology, 2020 Cues of maternal and paternal origins interact to control seed development, and the underlying molecular mechanisms are still far from clear. Here, we show that TOPOISOMERASE Iα (TOP1α), UP-FRAMESHIFT SUPPRESSOR 1 (UPF1), and TRANSPARENT TESTA GLABRA2 ...

Tetraploidy accelerates adaptation under drug selection in a fungal pathogen
Frontiers in Fungal Biology, 2022 Baseline ploidy significantly impacts evolutionary trajectories and, specifically, tetraploidy is associated with higher rates of adaptation relative to haploidy and diploidy.

A New Species of Arthropteris From Samoa
New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly < 3 cm wide vs.

Introgression and Divergence in a Young Species Group
Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT The process of speciation concerns often multiple diverging and interacting taxa, not only taxon pairs. Understanding the evolution of species' diversity and their persistence therefore requires insight into how gene flow and evolution of reproductive isolation shape groups of closely related species.

Plant Direct, Volume 10, Issue 4, April 2026.ABSTRACT Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and evaluated the cross‐resistance patterns conferred by each mutation to various ALS‐inhibiting ...
