Autotetraploid plant production in endemic Onobrychis elata with colchicine treatments

open access: yesJournal 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

Techniques of producing monosex or sterile population of fish for aquaculture -- a review of selected literature [PDF]

open access: yes, 1993
The need to develop techniques that can make the male grow faster in many species of fish as well as the female in some other species cannot be over-emphasized.

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

open access: yesBiological 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 ...

Notch Activation Is Associated with Tetraploidy and Enhanced Chromosomal Instability in Meningiomas

open access: yesNeoplasia: An International Journal for Oncology Research, 2008
The Notch signaling cascade is deregulated in diverse cancer types. Specific Notch function in cancer is dependent on the cellular context, the particular homologs expressed, and cross-talk with other signaling pathways.

Deregulated Aurora‐B induced tetraploidy promotes tumorigenesis

open access: yesThe FASEB Journal, 2009
High expression of Aurora‐B has been observed in various cancers, and inhibition of this kinase has been shown to halt cellular proliferation. However, the mechanism of effect of Aurora‐B on cellular transformation has not been fully explored. Here, we show that overexpression of Aurora‐B in murine epithelial cells promotes generation of tetraploids ...

Self-Renewal Signalling in Presenescent Tetraploid IMR90 Cells

open access: yesJournal 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.

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

open access: yesJournal 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 ...

Induced Tetraploidy in Melandrium album [PDF]

open access: yesNature, 1938
IN the flowering plants, the problem of polyploidy in relation to diœcism is an extraordinarily attractive one, since it should be possible in this way to get additional proof of the balance theory of sex determination.

Characterization of Expression of the KCNE Gene Family in Zebrafish, Danio rerio [PDF]

open access: yes, 2011
The KCNE gene family codes for five transmembrane accessory proteins, minK related peptides or Mirps, involved in the modification of voltage-gated potassium (Kv) channels, K+ selective pores vital in the regulation of membrane potential and ...
