Polyploidy in the Conifer Genus Juniperus: An Unexpectedly High Rate

Frontiers in Plant Science, 2019
Recent research suggests that the frequency of polyploidy may have been underestimated in gymnosperms. One notable example is in the conifer genus Juniperus, where there are already a few reports of polyploids although data are still missing for most ...

Synthetic Polyploidy in Grafted Crops [PDF]

, 2020
International audienceSynthetic polyploids have been extensively studied for breeding in the last decade. However, the use of such genotypes at the agronomical level is still limited.

Polyploidy induction of raspberry species (Rubus) using colchicine and oryzalin

Technology in Horticulture, 2023
Raspberry (Rubus spp.) is a fruit crop used in many products across the United States. Commercial production of raspberry in North Dakota is challenging due to lack of cultivars with winter hardiness.

Polyploidy can drive rapid adaptation in yeast [PDF]

, 2015
Polyploidy is observed across the tree of life, yet its influence on evolution remains incompletely understood1–4. Polyploidy, usually whole genome duplication (WGD), is proposed to alter the rate of evolutionary adaptation.

Polyploidy in liver development, homeostasis and disease

, 2020
International audiencePolyploidy (or whole-genome duplication) is the condition of having more than two basic sets of chromosomes. Polyploidization is well tolerated in many species and can lead to specific biological functions.

Production of autotetraploid plants by in vitro chromosome engineering in Allium hirtifolium

Horticultural Plant Journal, 2023
Persian shallot has been propagated vegetatively through daughter bulbs and has a narrow genetic base. In the present study, to create genetic diversity in terms of ploidy level, the effects of in vitro polyploidization were investigated on morphological,

Polyploidy in Gymnosperms [PDF]

Evolution, 1959
The gymnosperms constitute a primitive group of seed plants which have a considerable evolutionary interest. A substantial amount of literature on the morphology of the group exists, but very little has been written about the various cytogenetic factors responsible for evolution within the group.

Cellular polyploidy in organ homeostasis and regeneration [PDF]

, 2023
Polyploid cells, which contain more than one set of chromosome pairs, are very common in nature. Polyploidy can provide cells with several potential benefits over their diploid counterparts, including an increase in cell size, contributing to organ ...

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq

Advanced Science, EarlyView.
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...
