Effect of Ploidy in Photoreactivation.

Experimental 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.

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 chromosome number and heterochromatin distribution pattern suggest differentiation among species of the Stylosanthes scabra-seabrana complex [PDF]

Anais da Academia Brasileira de Ciências
The genus Stylosanthes has economic importance in semi-arid regions and requires studies that reveal complex relationships between species involving different ploidies.

Pathways to polyploidy : indications of a female triploid bridge in the alpine species Ranunculus kuepferi (Ranunculaceae) [PDF]

, 2017
Polyploidy is one of the most important evolutionary processes in plants. In natural populations, polyploids usually emerge from unreduced gametes which either fuse with reduced ones, resulting in triploid offspring (triploid bridge), or with other ...

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.

Surviving the Storm: The Role of Poly‐ and Depolyploidization in Tissues and Tumors

Advanced Science
Polyploidization and depolyploidization are critical processes in the normal development and tissue homeostasis of diploid organisms. Recent investigations have revealed that polyaneuploid cancer cells (PACCs) exploit this ploidy variation as a survival ...

nQuire: a statistical framework for ploidy estimation using next generation sequencing [PDF]

, 2018
BACKGROUND: Intraspecific variation in ploidy occurs in a wide range of species including pathogenic and nonpathogenic eukaryotes such as yeasts and oomycetes.

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 ...

Red rot disease resistance in interspecific hybrids of sugarcane derived from diverse cytotypes of Saccharum spontaneum L.

Journal of Sugarcane Research
Red rot disease has caused major loss to sugarcane crops for more than a hundred years.  It  is caused by the fungal pathogen Colletotrichum falcatum Went.

Implications of hybridisation and cytotypic differentiation in speciation assessed by AFLP and plastid haplotypes : a case study of Potentilla alpicola La Soie [PDF]

, 2012
Background: Hybridisation is presumed to be an important mechanism in plant speciation and a creative evolutionary force often accompanied by polyploidisation and in some cases by apomixis. The Potentilla collina group constitutes a particularly suitable
