In Vitro Initiation, Regeneration, and Characterization of Plants Derived from Mature Tetraploid Floral Explants of Date Palm (Phoenix dactylifera L.)

open access: yesHorticulturae
A stable tetraploid date palm mutant with the potential for increased fruit size was recovered from a sectorial di-tetraploid chimera via the in vitro culture of flower explants.

Transcriptomic profiles of myxofibrosarcoma and undifferentiated pleomorphic sarcoma correlate with clinical and genomic features

open access: yesThe Journal of Pathology, Volume 264, Issue 3, Page 293-304, November 2024.
Abstract Myxofibrosarcoma (MFS) and undifferentiated pleomorphic sarcoma (UPS) are two common and aggressive subtypes of soft tissue sarcoma. The aim of this study was to assess potential transcriptomic differences between MFS and UPS tumours and to evaluate the extent to which differences in gene expression profiles were associated with genomic and ...

Marginal zone lymphomas in children and the young adult population; characterization of genetic aberrations by FISH and RT-PCR [PDF]

open access: yes, 2010
Marginal zone lymphomas present rarely in children and young adults as either primary nodal or extranodal disease and have an excellent prognosis. To date, chromosomal aberrations have not been analyzed in the pediatric and young adult population.

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

INDUCTION OF T ETRAPLOIDY IN RAINBOW TROUT (ONCHORHYNCHUS MYKISS) BY HEAT SHOCK

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2004
This study has been conducted for determination of optimum time and duration of thermal shock on tetraploidy induction in Rainbow trout. This study was carried out by induction of 28°C thermal shock in different times after fertilization (49.5, 54.0, 58 ...

In vitro regeneration ability of diploid and autotetraploid plants of Cichorium intybus L. [PDF]

open access: yes, 2014
Polyploidy has played a significant role in the evolutionary history of plants and is a valuable tool for obtaining useful characteristics. Because of the novelty of polyploids, comparison of their in vitro culture responses with diploids would be ...

An unusual T-cell childhood acute lymphoblastic leukemia harboring a yet unreported near-tetraploid karyotype

open access: yesMolecular Cytogenetics, 2011
Background Near-tetraploid (model #81-103) and near-triploid (model #67-81) karyotypes are found in around 1% of childhood acute lymphoblastic leukemia.

Sex Chromosome Evolution, Heterochiasmy, and Physiological QTL in the Salmonid Brook Charr Salvelinus fontinalis [PDF]

open access: yes, 2017
Whole-genome duplication (WGD) can have large impacts on genome evolution, and much remains unknown about these impacts. This includes the mechanisms of coping with a duplicated sex determination system and whether this has an impact on increasing the ...

Somatic tetraploidy in vertebrate neurons [PDF]

open access: yesCommunicative & Integrative Biology, 2010
The presence of polyploid neurons in the vertebrate nervous system has been a subject of debate since the 1960s. At that time, Purkinje cells were proposed to be tetraploid, but technical limitations impeded to reach a clear conclusion, and the current belief is that most vertebrate neurons are diploid.
