Interspecific hybridization of sturgeon species affects differently their gonadal development

Czech Journal of Animal Science, 2018
Gonad development in fish is generally assumed to be negatively influenced by interspecific hybridization, resulting in sterility or sub-sterility. However, this is not the case in sturgeons (Acipenseridae), in which fertile hybrids are common.

Dynamic ploidy changes drive fluconazole resistance in human cryptococcal meningitis

Journal of Clinical Investigation, 2019
BACKGROUND. Cryptococcal meningitis (CM) causes an estimated 180,000 deaths annually, predominantly in sub-Saharan Africa, where most patients receive fluconazole (FLC) monotherapy. While relapse after FLC monotherapy with resistant strains is frequently

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

, 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 ...

Ploidy and Size at Multiple Scales in the Arabidopsis Sepal[OPEN]

The Plant Cell, 2018
Ploidy and size correlate at multiple biological scales (subcellular, cellular, and organismal), but compensation effects dampen the effect of ploidy change on organ size.

Embryos Arising from Apronuclear (0PN) and Unipronuclear (1PN) Have Similar Euploidy Rates with Those from 2PN and Should be Considered for Transfer

Fertility & Reproduction, 2019
Background: Fertilisation assessment is routinely made at 16–18 hours post-ICSI and 18–20 hours post-insemination. However, the absence of pronuclei (PN) during standard fertilisation assessment does not necessarily indicate fertilisation failure.

Structure is more robust than other clustering methods in simulated mixed-ploidy populations

Heredity, 2019
Analysis of population genetic structure has become a standard approach in population genetics. In polyploid complexes, clustering analyses can elucidate the origin of polyploid populations and patterns of admixture between different cytotypes.

Interaction among ploidy, breeding system and lineage diversification.

New Phytologist, 2019
If particular traits consistently affect rates of speciation and extinction, broad macroevolutionary patterns can be interpreted as consequences of selection at high levels of the biological hierarchy.

Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

, 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.

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

, 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.
