PLoS ONE, 2020 Polyploidy has been an influential force in plant evolution, playing a crucial role in diversification. Differences in polyploid and diploid distributions have been long noted, with polyploid taxa especially abundant in harsh environments.

Automictic Reproduction in Interspecific Hybrids of Poeciliid Fish [PDF]
, 2007 SummaryAutomixis, the process whereby the fusion of meiotic products restores the diploid state of the egg, is a common mode of reproduction in plants but has also been described in invertebrate animals [1, 2].

Pistil transcriptome analysis to disclose genes and gene products related to aposporous apomixis in Hypericum perforatum L. [PDF]
, 2017 Unlike sexual reproduction, apomixis encompasses a number of reproductive strategies,which permit maternal genome inheritance without genetic recombination and syngamy.

Genome composition of 'Elatior'-begonias hybrids analyzed by genomic in situ hybridisation [PDF]
, 2010 Interspecific hybridization of various tuberous Begonia species hybrids with Begonia socotrana results in so-called 'Elatior'-begonias hybrids (B. x hiemalis Fotsch).

Unreduced gametes and neopolyploids in natural populations of Achillea borealis (Asteraceae) [PDF]
Heredity, 2006 Polyploidy is a major mechanism of speciation and adaptation, yet little is known about the origins of polyploids in natural species. I investigated gametic nonreduction and neopolyploid formation in natural tetraploid populations of Achillea borealis (Asteraceae), an autopolyploid complex consisting of tetraploid and hexaploid cytotypes.

Heat stress induces unreduced male gamete formation by targeting meiocyte translation
, 2022 ABSTRACT Heat stress promotes the formation of unreduced (2n) male gametes through meiotic restitution, a driving force of evolutionary polyploidisation. Here we report that the molecular mechanism underlying heat tolerance of the meiotic division program in Arabidopsis thaliana ...

TAXON, Volume 75, Issue 2, April 2026.Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Evidence of unreduced gamete production from interspecific crosses between Gossypium hirsutum and G. herbaceum [PDF]
, 2009 In order to analyze the gene flow between the allotetraploid cultivated cotton (Gossypium hirsutum, AADD, 2n=52) and the wild diploid (G. herbaceum, AA, 2n=26), the possibility of natural hybridization between these two cotton species has been ...

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.
