Phylogenetic relationships in Betula (Betulaceae) based on AFLP markers [PDF]

open access: yes, 2008
The genus Betula comprises various species in boreal and temperate climate zones of the Northern Hemisphere. The taxonomy of Betula is controversial and complicated by parallel evolution of morphological traits, polyploidization events, and extensive ...

Chromosome‐scale reference genome of Pectocarya recurvata, the species with the smallest reported genome size in Boraginaceae

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.

Ploidy determination of Canadida albicans [PDF]

open access: yesJournal of Bacteriology, 1979
The dimorphic yeast Candida albicans, as a member of the fungi imperfecti, has been assumed to be in the haploid, or imperfect, state. The deoxyribonucleic acid content of this species has been measured by flow microfluorometry, a technique capable of analyzing single cells.

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

open access: yesThe 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 ...

Physiology and Robustness of Yeasts Exposed to Dynamic pH and Glucose Environments

open access: yesBiotechnology and Bioengineering, EarlyView.
The authors investigated how three Saccharomyces cerevisiae strains respond to dynamic substrate and pH oscillations using dynamic microfluidic single‐cell cultivation (dMSCC) and intracellular biosensors. By combining performance and robustness analysis of selected intracellular parameters, growth and morphological analysis, the authors identified ...

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Effect of Ploidy in Photoreactivation.

open access: yesExperimental Biology and Medicine, 1952
SummaryThe survival fractions of diploid and haploid strains of S. cerevisiae after ultraviolet irradiation (2537 A.U.) have been obtained, compared, and modified by photoreactivation following the initial irradiation. The haploid survival follows a sigmoid curve and is smaller than the diploid at the same dose.

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

open access: yesDevelopmental 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.

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

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

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

open access: yesExploration, 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 ...
