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 ...

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.

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,

Aurkin-A, a TPX2-Aurora A small molecule inhibitor disrupts Alisertib-induced polyploidy in aggressive diffuse large B cell lymphoma

Neoplasia: An International Journal for Oncology Research
Chemotherapy induced polyploidy is a mechanism of inherited drug resistance resulting in an aggressive disease course in cancer patients. Alisertib, an Aurora Kinase A (AK-A) ATP site inhibitor, induces cell cycle disruption resulting in polyaneuploidy ...

The Impact of Age and Carbon Tetrachloride on Hepatic Polyploidy in Albino Rats (A Histological and Immunohistological Study) [PDF]

Al-Azhar International Medical Journal
Background: Polyploidy, a condition where cells contain more than two sets of homologous chromosomes, is a unique feature of hepatocytes. However, its biological significance remains incompletely understood.

Variance of allele balance calculated from low coverage sequencing data infers departure from a diploid state

BMC Bioinformatics, 2022
Background Polyploidy and heterokaryosis are common and consequential genetic phenomena that increase the number of haplotypes in an organism and complicate whole-genome sequence analysis.

Polyploidy and mTOR signaling: a possible molecular link

Cell Communication and Signaling
Polyploidy is typically described as the condition wherein a cell or organism has more than two complete sets of chromosomes. Occurrence of polyploidy is a naturally occurring phenomenon in the body’s development and differentiation processes under ...
