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

GAMETAS NÃO REDUZIDOS NO MELHORAMENTO DE PLANTAS UNREDUCED GAMETES IN PLANT BREEDING
Ciência Rural, 2001 Nesta revisão são abordados o papel dos gametas não reduzidos (gametas 2n), ou seja, aqueles com o número somático de cromossomos, na origem dos poliplóides, e sua utilização no melhoramento genético de plantas.

Nature Communications, 2023 The formation and consequences of polyploidization in animals with clonal reproduction remain largely unknown. Clade I root-knot nematodes (RKNs), characterized by parthenogenesis and allopolyploidy, show a widespread geographical distribution and ...

Shared pedigree relationships and transmission of unreduced gametes in cultivated banana. [PDF]
Ann Bot, 2023 Abstract Background and Aims Cultivated bananas resulted from inter(sub)specific hybridizations involving Musa species and subspecies (M. acuminata subspecies, M. schizocarpa, M. balbisiana) and the subsequent selection, centuries ago, of hybrids with parthenocarpic, seedless fruits.

Production of polyploids and unreduced gametes in Lilium auratum × L. henryi hybrid. [PDF]
Int J Biol Sci, 2013 Intergenomic F1 hybrids between L. auratum x L. henryi and their BC1 progeny were investigated through genomic in situ hybridization technique (GISH) to determine their potential value in lily breeding. We confirmed that F1 intergenomic hybrids possessed a set of chromosomes (x=12) from both parents and that flowers of the F1 auratum × henryi hybrid ...

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

Multiple hybrid zones involving four Cardamine species and their triploid progeny: watching allopolyploid speciation in action? [PDF]
New PhytolSummary Hybrid zones provide excellent opportunities to study evolutionary processes linked to interspecific gene flow, including introgression, genetic erosion, polyploid establishment, and speciation. The genus Cardamine (Brassicaceae) serves as an excellent model for polyploid evolution, including one of the few well‐documented neo‐allopolyploid ...

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

Advances and Perspectives for Polyploidy Breeding in Orchids
Plants, 2022 The orchid market is a dynamic horticultural business in which novelty and beauty command high prices. The two main interests are the development of flowers, from the miniature to the large and showy, and their fragrance.
