Mononuclear Diploidy at the Heart of Cardiomyocyte Proliferation [PDF]
Cell Stem Cell, 2017 Reporting in Nature Genetics, Patterson et al. (2017) show that adult mammalian hearts possess an innate capacity to regenerate, which depends on a small population of mononuclear diploid cardiomyocytes. These cells undergo karyokinesis and cytokinesis, raising the possibility that endogenous cardiac muscle cells can be stimulated to proliferate for ...

Molecular and immunohistochemical characteristics of complete hydatidiform moles
Balkan Journal of Medical Genetics, 2017 Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic ...

Journal of Integrative Plant Biology, EarlyView.Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...

Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]
PLoS Genetics, 2016 Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...

Parthenocarpy and Self-Incompatibility in Mandarins
Agronomy, 2021 Citrus reproductive biology is complex. One of its characteristic features is parthenocarpy that enables seedless fruit production. Citrus parthenocarpy and self-incompatibility knowledge is only partial and sometimes discrepant.

Journal of Phycology, EarlyView.Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Caspase 2 in mitotic catastrophe: The terminator of aneuploid and tetraploid cells
Molecular & Cellular Oncology, 2017 Mitotic catastrophe is an oncosuppressive mechanism that targets cells experiencing defective mitoses via the activation of specific cell cycle checkpoints, regulated cell death pathways and/or cell senescence.

Induction of gynogenesis by heterogenous sperm and cold shock treatment in Epinephelus fuscoguttatus
Reproduction and Breeding, 2021 Gynogenesis is a chromosome set manipulation technique to accelerate inbred lines used for genomics analysis and genetic breeding. Groupers are hermaphroditic fish whereby they sexually mature as females and subsequently change sex to male. Production of

Plant Breeding, EarlyView.ABSTRACT Unreduced gametes naturally promote polyploidization and are valuable in breeding polyploid offspring. Bigleaf hydrangea (Hydrangea macrophylla ssp. macrophylla), a major ornamental crop, has shown spontaneous polyploidization rates ranging from 0% to 94% in previous crosses.

Ploidy analysis among Citrus mutants using leaf meristematic tissue
Journal of Horticultural Sciences, 2022 A promising method for preparing metaphase spread for counting the number of chromosomes from the emerging shoot tissue is described in this report. In the present study, we adopted enzymatic digestion of shoot tips to analyse the chromosome number. The
