Variations in morphological, biochemical and phytochemical traits of diploid and induced tetraploid plants of downy thorn-apple (Datura innoxia Mill.)

Journal of Medicinal Plants, 2022
Background: Datura species produce a wide range of tropane alkaloids with medicinal values. D. innoxia is a species of the Datura genus which is poisonous and has an unpleasant odor due to the presence of tropane alkaloids.

Tetraploidy-associated centrosome overduplication in mouse early embryos

Communicative & Integrative Biology, 2018
Recently, we observed that tetraploidization of certain types of human cancer cells resulted in upregulation of centrosome duplication cycles and chronic generation of the extra centrosome. Here, we investigated whether tetraploidy-linked upregulation of

The Induction of Tetraploidy in Salmonids

Journal of the World Aquaculture Society, 1986
AbstractThe induction of tetraploidy was attempted in three intraspecies crosses (autotetraploid) of sal‐monid: chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch) and rainbow trout (Salmo gairdneri), and in the interspecies hybrid (allotetraploid) coho × Atlantic salmon (Salmo salar).Pressure treatments of 6.2 × 104 kPa (9,000 psi ...

Gametogenesis and nucleotypic effects in the tetraploid red vizcacha rat, Tympanoctomys barrerae (Rodentia, Octodontidae)

Biological Research, 2004
Nucleotypic effects link DNA content with nuclear size and cell dimensions of reproductive cells in polyploid organisms. We studied the gametogenesis of the allotetraploid rodent Tympanoctomys barrerae, aiming to determine these effects in reproductive ...

Autotetraploid plant production in endemic Onobrychis elata with colchicine treatments

Journal of Applied Botany and Food Quality, 2019
This study aimed to induce autotetraploidy in endemic Onobrychis elata plants by colchicine treatment of seeds or seedlings. Colchicine was applied to O. elata directly on germinated seeds, pre-germinated seeds (root length of 3-8 mm), and apical regions

Increasing the Production of Valuable Phytopharmaceutical Compounds by Chromosome Manipulation: Perspectives and Techniques of Induction and Selection of Polyploid Plants

Journal of Medicinal Plants, 2014
Polyploidy is one of the widespread phenomena in plant kingdom, which has a vital role in evolution and speciation of plants and is usually accompanied by significant changes in morphology, cell and organ size, expression patterns of genes, respiration ...

Self-Renewal Signalling in Presenescent Tetraploid IMR90 Cells

Journal of Aging Research, 2011
Endopolyploidy and genomic instability are shared features of both stress-induced cellular senescence and malignant growth. Here, we examined these facets in the widely used normal human fibroblast model of senescence, IMR90.
