Plastic Germination, Temporal Niche Partitioning and Emergent Assortative Mating in Annual Plants
Ecology Letters, Volume 29, Issue 2, February 2026.Temporal environmental fluctuations can drive genetic diversity and species coexistence via the storage effect. Using eco‐evolutionary models of annual plants, we show that adaptive plasticity in seed germination readily evolves and promotes genetic diversification by facilitating temporal niche partitioning, and in sexual populations can initiate ...

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

Under-dominance constrains the evolution of negative autoregulation in diploids [PDF]
, 2012 Regulatory networks have evolved to allow gene expression to rapidly track changes in the environment as well as to buffer perturbations and maintain cellular homeostasis in the absence of change.

Molecular Ecology, Volume 35, Issue 3, February 2026.ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

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 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 ...

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.

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.
