Plants, 2019 Lantana (Lantana camara L., Verbenaceae) is an important ornamental crop, yet can be a highly invasive species. The formation of unreduced female gametes (UFGs) is a major factor contributing to its invasiveness and has severely hindered the development ...

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).

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.

Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica. [PDF]
New PhytolSummary Polyploidization, followed by genome downsizing, is a recurrent evolutionary cycle that dramatically reshapes genome structure. Newly formed polyploids must quickly adjust their cell division machinery to maintain stable chromosome inheritance, while long‐term stabilization involves rediploidization, returning the genome to a diploid‐like state.

Production of Triploid Hydrangea macrophylla via Unreduced Gamete Breeding [PDF]
HortScience, 2017 Hydrangea macrophylla (Thunb.) Ser., florist’s or bigleaf hydrangea, is the most economically important member of the Hydrangea genus, which accounted for over $120,000,000 in U.S. nursery sales in 2014. Both diploid and triploid H. macrophylla cultivars exist and there is some evidence that triploidy leads to larger plant and floral structures.

Problematic octaploid forms and a new chromosome number in the genus Achillea L., 2n = 126
Acta Societatis Botanicorum Poloniae, 2014 Among the offspring of a problematic form of Achillea sp., a 2n = 126 seedling which probably arose as the result of fusion of unreduced octo- and hexaploid gametes (72 + 54) was found along with seedlings having an octaploid chromosome number (2n = 72).

Applied Biosciences, 2023 Medicago sativa (2n = 4x = 32) and M. arborea (2n = 4x = 32) were thought to be reproductively isolated until hybrids (Alborea) were produced by sexual reproduction for the first time in 2003 in Wisconsin. The hybrids were asymmetric, at or near 2n = 4x =

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]
, 2016 Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific

Occurrence of Unreduced Female Gametes Leads to Sexual Polyploidization in Lantana [PDF]
Journal of the American Society for Horticultural Science, 2009 Lantana camara , a member of the verbena family, is a popular ornamental yet highly invasive plant. It can escape from cultivation through seed dispersal and can contaminate native lantana species ( Lantana depressa ) through cross-pollination. Ploidy manipulation is being

Caryologia, 2020 Cytomictic behaviour of chromosomes among pollen mother cells was observed in mutagenic studies in cluster bean (Cyamopsis tetragonoloba (L.) Taub.). The study of pollen mother cells (PMC) revealed various chromosomal aberrations among which cytomixis ...
