Clues of ancient incomplete lineage sorting during bivalve evolution undermine support for Heterodonta

Cladistics, EarlyView.
Abstract A long‐standing challenge in phylogenomics has been the resolution of relationships originated from ancient radiations. In these cases, phenomena such as incomplete lineage sorting can increase the support for conflicting resolutions. Most of the diversity in the Class Bivalvia originated during an Ordovician radiation; indeed, several deep ...

Cytological and Molecular Genetic Analysis of Polyembryony in an Apricot × Almond Interspecific Hybrid Cultivar

Horticulturae
Polyembryony holds great potential for heterosis fixation and germplasm innovation in plant breeding. This study elucidated the origin and cytogenetic basis of polyembryony in ‘Jingren 4’, which is an interspecific hybrid cultivar of apricot × almond ...

Application of Flow Cytometry to Determine Cell DNA Content in the Genetic Breeding of Fish

Fishes
In the field of fish genetic breeding, accurately determining the DNA content and ploidy of fish is of great significance. This article introduces the use of flow cytometry (FCM) to measure the DNA content and conduct ploidy analysis by sampling ...

Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1

The FEBS Journal, EarlyView.
In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus

The FEBS Journal, EarlyView.
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

DETERMINATION OF THE ORIGIN OF REGENERATED FLAX PLANTS IN ANTHER CULTURE

Вавиловский журнал генетики и селекции, 2014
The possibility to diagnose the ploidy of cells producing regenerated plants in vitro in anther culture has been studied. It is shown by the example of oil flax that population analysis of regenerated plants for segregation on the basis of a marker trait

Influence of Ploidy and Genetic Background on Stress Tolerance of Intraspecific Yeast Hybrids

Microbial Biotechnology
Hybrid vigour, or heterosis, is widely exploited in yeast strain improvement. Yet, how ploidy and genetic background jointly shape heterosis across industrially relevant stresses remains unclear.

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Ensemble-Based Refinement of Landmark Annotations for DNA Ploidy Analysis in Digital Pathology

Applied Sciences
Reliable evaluation of image segmentation algorithms in digital pathology depends on high-quality annotation datasets. Landmark-type annotations, essential for cell-counting analyses, are often limited in quality or quantity for segmentation benchmarking,

Black Carp Mylopharyngodon piceus reproductive development and maturation in the Mississippi River basin

Journal of Fish Biology, EarlyView.
Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...
