Corrigenda: Bhowmick BK, Jha S (2022) A critical review on cytogenetics of Cucurbitaceae with updates on Indian taxa. Comparative Cytogenetics 16(2): 93–126. https://doi.org/10.3897/compcytogen.v16.i2.79033 [PDF]

open access: yesComparative Cytogenetics
The cytogenetic relationships in the species of Cucurbitaceae are becoming immensely important to answer questions pertaining to genome evolution. Here, a simplified and updated data resource on cytogenetics of Cucurbitaceae is presented on the basis of ...

Accelerated Growth, Differentiation, and Ploidy with Reduced Proliferation of Right Ventricular Cardiomyocytes in Children with Congenital Heart Defect Tetralogy of Fallot

open access: yesCells, 2022
The myocardium of children with tetralogy of Fallot (TF) undergoes hemodynamic overload and hypoxemia immediately after birth. Comparative analysis of changes in the ploidy and morphology of the right ventricular cardiomyocytes in children with TF in the

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yes, 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

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]

open access: yes, 2020
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Manipulating Unisexual–Sexual Reproduction Transition to Engineer Genome‐Reconstructed Polyploids

open access: yesAdvanced Science, EarlyView.
This study developed an efficient approach to generate genome‐reconstructed polyploids involving unisexual gynogenetic Carassius gibelio, sexual C. auratus, and sexual C. cuvieri. The selected superior clone inherited gynogenesis ability of C. gibelio and herpesvirus resistance of wild C.

Genome Size and Karyotype Studies in Five Species of Lantana (Verbenaceae)

open access: yesHortScience, 2021
Lantana species are an important component of the U.S. environmental horticulture industry. The most commonly produced and used species are L. camara and, on a smaller scale, L. montevidensis. Both were introduced to the United States from Central and/or

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).

CATECHOLAMINE SECRETION AND PLOIDY IN PHAEOCHROMOCYTOMA

open access: yesInternational Journal of Clinical Practice, 2000
SUMMARYThe aim was to evaluate 24 hr urine catecholamine, HMMA and HVA excretion in relation to ploidy in phaeochromocytoma. Data from five diploid and nine tetraploid tumours showed a significant reduction in urine noradrenaline (p=0.02) and HMMA (p=0.03) in diploid tumours but no difference in adrenaline, dopamine and HVA excretion using the Mann ...

Patient With Prolidase Deficiency due to an Homozygous PEPD Variant, Induced by Paternal Uniparental Isodisomy of Chromosome 19

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Uniparental disomy (UPD) is a rare phenomenon in which both copies of a chromosome are inherited from a single parent. This can lead to genomic imprinting disorders and recessive disorders due to the presence of recessive pathogenic variants in both alleles. Additionally, depending on the mechanisms by which UPD occurs, mosaic aneuploidies may

Comparative analysis of cell-free DNA content in culture medium and mitochondrial DNA copy number in porcine parthenogenetically activated embryos

open access: yesThe Journal of Reproduction and Development, 2020
We examined the effect of ploidy on mitochondrial DNA (mtDNA) copy number in embryos and the amount of cell-free mitochondrial and nucleic DNA content (cf-mtDNA and cf-nDNA) in spent culture medium (SCM).
