A natural histone H2A variant lacking the Bub1 phosphorylation site and regulated depletion of centromeric histone CENP-A foster evolvability in Candida albicans. [PDF]

open access: yes, 2019
Eukaryotes have evolved elaborate mechanisms to ensure that chromosomes segregate with high fidelity during mitosis and meiosis, and yet specific aneuploidies can be adaptive during environmental stress.

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]

open access: yes, 2017
BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...

A comparison of methods for determining ploidy in white sturgeon (Acipenser transmontanus) [PDF]

open access: yes, 2019
Release of sturgeon with abnormal ploidy into the wild may result in reduced fitness due to lowered fertility in the F2 and subsequent generations. Further, there is evidence that ploidy affects reproductive development and caviar yield.

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

open access: yes, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

Molecular and functional profiling unravels targetable vulnerabilities in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
We used whole exome and RNA‐sequencing to profile divergent genomic and transcriptomic landscapes of microsatellite stable (MSS) and microsatellite instable (MSI) colorectal cancer. Alterations were classified using a computational score for integrative cancer variant annotation and prioritization.

Niche divergence and limits to expansion in the high polyploid Dianthus broteri complex [PDF]

open access: yes, 2019
Niche evolution in plant polyploids remains controversial and evidence for alternative patterns has been reported. Using the autopolyploid Dianthus broteri complex (2×, 4×, 6× and 12×) as a model, we aimed to integrate three scenarios – competitive ...

PLOIDY AND GENE EXPRESSION IN CLEMENTINE

open access: yesActa Horticulturae, 2015
Polyploidy has long been recognized as an important force in the evolution of flowering plants and often results in novel phenotypes having advantages in adaptation and major interest for agriculture. Many crops, including citrus, are bred to a higher level of ploidy in search of desirable traits.

Ploidy and the Causes of Genomic Evolution [PDF]

open access: yesJournal of Heredity, 2009
Genomes vary dramatically in size and in content. This variation is driven in part by numerous polyploidization events that have happened over the course of eukaryotic evolution. Experimental evolution studies, primarily using the yeast Saccharomyces cerevisiae, provide insights into the immediate fitness effects of ploidy mutations, the ability of ...

Adverse prognosis gene expression patterns in metastatic castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
We aggregated a cohort of 1012 mCRPC tissue samples from 769 patients and investigated the association of gene expression‐based pathways with clinical outcomes. Loss of AR signaling, high proliferation, and a glycolytic phenotype were independently prognostic for poor outcomes, and an adverse transcriptional feature score incorporating these pathways ...

Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

open access: yes, 2015
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown.
