Variance of ploidy in Candida albicans [PDF]

Journal of Bacteriology, 1982
Determination of ploidy was performed on isolates of Candida albicans from clinical sources by measuring nuclear DNA content with fluorescent microscope photometry. By this criterion and UV irradiation survival experiments, haploid, diploid, and tetraploid strains were identified in this organism.

Topological and variational modularity: A case study using the pectoral girdle across the Chrosomus eos‐neogaeus hybridization complex

The Anatomical Record, EarlyView.
Abstract Modularity and integration are key developmental properties and have remained central in evo‐devo research because of how they relate to evolvability. While modularity and integration have commonly been assessed with landmark‐based geometric morphometrics (GMM), other methods such as anatomical network analysis (AnNA) are increasingly being ...

The mexican potato species Solanum neoantipoviczii BUK. (= S. stoloniferum Schlechtd.) from the taxonomic series Longipedicellata BUK. and its use in interspecific hybridization

Труды по прикладной ботанике, генетике и селекции, 2019
Background. There are more than 200 tuber-bearing species in the genus Solanum L. Many of them possess valuable traits able to improve some characteristics in present-day potato cultivars.

Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius)

Developmental Dynamics, EarlyView.
Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.

Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]

, 2020
Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

ASPM Induces Radiotherapy Resistance by Disrupting Microtubule Stability Leading to Chromosome Malsegregation in Non‐Small Cell Lung Cancer

Exploration, EarlyView.
Abnormal spindle‐like microcephaly‐associated protein helps radiotherapy resistant cells to evade spindle checkpoint surveillance and complete cell division after irradiation through destruction of microtubule stability, with subsequent increases in chromosome mis‐segregation and deteriorating chromosomal stability during mitosis to promote ...

Genome composition of 'Elatior'-begonias hybrids analyzed by genomic in situ hybridisation [PDF]

, 2010
Interspecific hybridization of various tuberous Begonia species hybrids with Begonia socotrana results in so-called 'Elatior'-begonias hybrids (B. x hiemalis Fotsch).

De Novo Whole Genome Assemblies of Unusual Case‐Making Caddisflies (Trichoptera) Highlight Genomic Convergence in the Composition of the Major Silk Gene (h‐fibroin)

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The major silk gene, h‐fibroin, was annotated in high‐quality genomes of two unusual case‐making Trichoptera. H‐Fibroin of Limnocentropus insolitus shows a similar amino acid composition to other case‐making species, while the amino acid composition of h‐fibroin of Phryganopsyche brunnea resembles that of retreat‐making species.
