Ophrys fusca and Ophrys dyris (Orchidaceae) – constancy of tetraploidy amongst populations in Central Portugal [PDF]

, 2017
Ophrys is amongst the best known orchid genera and is an established system for the study of pollinatormediated floral evolution. Two species, Ophrys fusca s.l. and Ophrys dyris (= O. omegaifera subsp.

Pregnancy Outcomes and Postnatal Health From Transferred Mosaic Embryos Following Preimplantation Genetic Testing for Aneuploidy

iNew Medicine, EarlyView.
This illustration synthesizes the methods and conclusion of this study, demonstrating that the transfer of mosaic embryos following reimplantation genetic testing for aneuploidy does not increase the risk to postnatal health. ABSTRACT Next‐generation sequencing (NGS) has increased the detection of mosaic embryos during preimplantation genetic testing ...

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 ...

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.

Ploidy influences on metabolic substrate deposition of rainbow trout

Acta Scientiarum: Animal Sciences, 2019
Triploid fish are usually sterile. Thus, the energy and nutrients intended for sexual maturation may be available to enhance flesh quality and physical growth.

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]

, 2020
Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Isoetes ×atruensis (Isoetaceae – Lycopodiopsida), a new interspecific sterile hybrid from Rajasthan of Western India

Nordic Journal of Botany, EarlyView.
Isoetes ×atruensis hyb. nov. is shown to be a triploid (2n = 3× = 33 + 1) sterile interspecific hybrid between diploid (2n = 2× = 22 + 1) I. coromandelina and tetraploid (2n = 4× = 44 + 1) I. rajasthanensis. It has been found in two locations in Rajasthan, India.

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.

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

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
