The Polyploid State Restricts Hepatocyte Proliferation and Liver Regeneration in Mice

Hepatology, 2019
The liver contains a mixture of hepatocytes with diploid or polyploid (tetraploid, octaploid, etc.) nuclear content. Polyploid hepatocytes are commonly found in adult mammals, representing ~90% of the entire hepatic pool in rodents.

Bulbil formation in stress: Crucial role of triploid fitness in mixed ploidy dynamics in Costus speciosus

Plant Species Biology, EarlyView.
Upon prolonged waterlogging, a Costus speciosus plant developed bulbils at stem node. Karyotype analysis, nucleolar staining, and anatomical study revealed its triploid status and developmental aspects. Prevalence of tetraploid, abundance, and unique reproductive fecundity of the triploid, indicates its determinant role in coexistence of the multiple ...

Polyploid plants have faster rates of multivariate niche differentiation than their diploid relatives.

Ecology Letters, 2019
Polyploid speciation entails substantial and rapid postzygotic reproductive isolation of nascent species that are initially sympatric with one or both parents.

Revised phylogeny of the Inula complex group (Asteraceae: Inuleae) with a recircumscription of Carpesium and establishment of a new genus Cladocarpesium

Journal of Systematics and Evolution, EarlyView.
Cladocarpesium T. Deng & Qun Liu, gen. nov. (Separated from Carpesium) is established with Cladocarpesium abrotanoides (L.) T. Deng & Qun Liu designated as the type species. The new genus is morphologically distinct from Carpesium s.str. by its sympodial growth form (typically producing three branches), sessile capitula, and three‐seriate phyllaries ...

Has the Polyploid Wave Ebbed?

Frontiers in Plant Science, 2020
There was a wave of whole genome duplications (WGD) during and subsequent to the K-Pg interface, which was followed by an increase in the proportion of species that were polyploid.

Biodiversity Genomics Research Practices Require Harmonising to Meet Stakeholder Needs in Conservation

Molecular Ecology, EarlyView.
ABSTRACT Biodiversity resilience relies on genetic diversity, which sustains the evolutionary potential of organisms in dynamic ecosystems. Genomics is a powerful tool for accurately estimating genetic diversity across genomes of species and populations.

Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae) [PDF]

, 2018
The digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic consequences of organism-wide

Roles of cell fusion, hybridization and polyploid cell formation in cancer metastasis

World Journal of Clinical Oncology, 2020
Cell-cell fusion is a normal biological process playing essential roles in organ formation and tissue differentiation, repair and regeneration. Through cell fusion somatic cells undergo rapid nuclear reprogramming and epigenetic modifications to form ...

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

New Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...
