Target Capture Sequencing Provides Insights Into Hybridogenetic Water Frogs

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The genomics of European frogs of the genus Pelophylax are intriguing due to their propensity to hybridise, the prevalence of polyploidy, and the unusual hemiclonal hybridogenetic complexes formed in many populations. This study examines the use of target capture sequencing using the Frog Cap bait set to investigate these complex systems.

DNA lesions induced by replication stress trigger mitotic aberration and tetraploidy development. [PDF]

PLoS ONE, 2010
During tumorigenesis, cells acquire immortality in association with the development of genomic instability. However, it is still elusive how genomic instability spontaneously generates during the process of tumorigenesis.

A Reevaluation of Tetraploidy in the Alzheimer’s Disease Brain [PDF]

Neurodegenerative Diseases, 2009
Alzheimer’s disease (AD) is characterized by extensive neuronal death in distinct brain regions, including the frontal cortex and hippocampus, although the specific mechanisms of neuronal degeneration in AD remain a topic of intense scientific pursuit.

GT‐Seq Panel Development for Species Identification and Parentage Analysis of Closely Related Hybridising Scaphirhynchus Sturgeons

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Hatchery supplementation is vital for conserving dwindling fish populations. Effective augmentation requires distinguishing hatchery‐origin from wild individuals and accurately identifying species, particularly in systems where closely related species coexist.

CHROMOSOME NUMBERS OF CHILEAN PTERIDOPHYTES: FIRST CONTRIBUTION NUMEROS CROMOSOMICOS DE PTERIDOFITOS CHILENOS: PRIMERA CONTRIBUCION

Gayana: Botanica, 2006
Mitotic chromosome counts in Chilean pteridophytes confirm the diploidy described for Equisetum L. (2n = 216) and Blechnum L. (2n = 66), as well as the tetraploidy of Asplenium L. (2n = 144). Megalastrum spectabile (Kaulf.) A.R.Sm.

Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar

Biomolecules, 2015
There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains μ, δ and τ, respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, Atlantic salmon (Salmo salar)

Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]

PLoS Genetics, 2016
Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...

Optical genome mapping detects cryptic high‐risk and targetable abnormalities in adult AML

British Journal of Haematology, Volume 208, Issue 4, Page 1232-1239, April 2026.
Summary Acute myeloid leukaemia (AML) risk stratification relies on cytogenetic and molecular abnormalities defined by European LeukemiaNet (ELN) 2022. Conventional cytogenetic techniques, including chromosomal banding analysis (CBA) and fluorescence in situ hybridization, have limited resolution and may miss cryptic events. Optical genome mapping (OGM)

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, Volume 250, Issue 1, Page 629-647, April 2026.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.
