Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids [PDF]

Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Genetic fine-mapping of DIPLOSPOROUS in Taraxacum (dandelion; Asteraceae) indicates a duplicated DIP-gene [PDF]

, 2010
Background DIPLOSPOROUS (DIP) is the locus for diplospory in Taraxacum, associated to unreduced female gamete formation in apomicts. Apomicts reproduce clonally through seeds, including apomeiosis, parthenogenesis, and autonomous or pseudogamous ...

Elucidating mechanisms of unreduced gamete formation in Arabidopsis thaliana

, 2022
Die Meiose ist für die sexuelle Fortpflanzung unerlässlich, und Anomalien in diesem Prozess führen oft zu Polyploidie. Während der männlichen Meiose in Arabidopsis wird das JASON (JAS)-Protein benötigt, um das „Organellenband“ aufrechtzuerhalten, das eine physikalische Barriere für zwei sich trennende Chromosomengruppen in der Metaphase II darstellt ...

Unreduced gamete formation in plants: mechanisms and prospects [PDF]

, 2017
Polyploids, organisms with more than two sets of chromosomes, are widespread in flowering plants, including many important crop species. Increases in ploidy level are believed to arise commonly through the production of gametes that have not had their ...

Genome evolution in the allotetraploid frog Xenopus laevis [PDF]

, 2016
To explore the origins and consequences of tetraploidy in the African clawed frog, we sequenced the Xenopus laevis genome and compared it to the related diploid X. tropicalis genome. We characterize the allotetraploid origin of X.

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

The evolutionary significance of polyploidy [PDF]

, 2017
Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization are complex and variable, and they differ greatly between systems (clonal or ...

Conservation challenges and opportunities for native apple (Malus) species in Canada

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 134-156, January 2026.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Abnormal chromosome behavior during meiosis in the allotetraploid of Carassius auratus red var. (♀) × Megalobrama amblycephala(♂) [PDF]

, 2014
BACKGROUND: Allopolyploids generally undergo bivalent pairing at meiosis because only homologous chromosomes pair up. On the other hand, several studies have documented abnormal chromosome behavior during mitosis and meiosis in allopolyploids plants ...
