The frequency and importance of polyploidy in tropical rainforest tree radiations
New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

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

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

Ecology and Evolution, Volume 16, Issue 1, January 2026.Genome‐wide data from ddRADseq revealed a latitudinal gradient in genetic diversity in a Taiwanese endemic orchid. This study shows that genomic data not only can help us understand the evolutionary origins of genetic diversity in a species but also uncover its genetic reservoir for future conservation planning.

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.

The Overlooked Threat of Global Warming on Elasmobranch Fertility
Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

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 ...

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.
