Sexual polyploidization in red clover Poliploidização sexual em trevo vermelho [PDF]

open access: yesScientia Agricola, 2006
Because sexual polyploidization broadens genetic basis and supply plant breeders with more variability for the selection process, it can be useful in red clover breeding.

Unreduced Male Gamete Formation in Cymbidium and Its Use for Developing Sexual Polyploid Cultivars [PDF]

open access: yesFrontiers in Plant Science, 2020
Polyploidy plays an important role in crop improvement. Polyploid plants, particularly those produced through unreduced gametes (2n gametes), show increased organ size, improved buffering capacity for deleterious mutations, and enhanced heterozygosity ...

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

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
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.

Variation of DNA methylation and phenotypic traits following unilateral sexual polyploidization in Medicago [PDF]

open access: yesEuphytica, 2012
Sexual hybridization is an important generator of biodiversity and a powerful breeding tool. Hybridization can also overcome ploidy barriers when it involves 2n gametes, as in the case of unilateral sexual polyploidization (USP) that has been utilized in

Sexual polyploidization in plants--cytological mechanisms and molecular regulation. [PDF]

open access: yesNew Phytol, 2013
SummaryIn the plant kingdom, events of whole genome duplication or polyploidization are generally believed to occur via alterations of the sexual reproduction process. Thereby, diploid pollen and eggs are formed that contain the somatic number of chromosomes rather than the gametophytic number.

Leaf transcriptome differences between diploid and tetraploid bahiagrass. [PDF]

open access: yesPlant Genome
Abstract Polyploid individuals of the subtropical forage grass Paspalum notatum Flüggé (bahiagrass) exhibit distinct phenotypes, including apomixis, enhanced vigor, gigas effects, and increased stress tolerance. While apomixis‐based breeding programs supported by molecular tools have improved agronomic traits such as growth habit, forage dry matter ...

Metabolic Consequences of Hybridization in European Water Frogs (<i>Pelophylax esculentus</i> complex). [PDF]

open access: yesEcol Evol
Our study links hybridization, ploidy, and cell size to metabolic performance under varying oxygen and temperature conditions in an amphibian larval model. By revealing physiological constraints tied to genotype and mitonuclear mismatch, it provides mechanistic insights into how hybrid and polyploid organisms may respond to environmental change ...

A Trojan horse inside the gates: Alien-native mating interactions in mixed populations of Solidago taxa. [PDF]

open access: yesPlant Biol (Stuttg)
DAPI flow cytometry identified post‐invasion processes—hybridisation, introgression, and polyploidization—in mixed populations of Solidago canadensis, S. virgaurea and S. ×niederederi. Abstract The establishment and possible impacts of alien–native hybrids depend on their formation frequency and ability to spread using generative and vegetative ...

Hybridity of mainly asexually propagating duckweeds in genus Lemna - dead end or breakthrough? [PDF]

open access: yesNew Phytol
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Polyploid cytotypes and formation of unreduced male gametes in wild and cultivated fennel (Foeniculum vulgare Mill.)

open access: yesCaryologia, 2023
. Foeniculum vulgare Mill. (2n=22) is an herbaceous species native to the Mediterranean region and naturalized in many temperate areas around the world. It includes subsp. piperitum and subsp.
