EVALUATION OF SOME GROWTH CHARACTERS AND ALKALOID PRODUCTIVITY OF DIPLOIDY AND TETRAPLOIDY FORMS OF Datura stramonium AND Datura innoxia PLANTS [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2004
Field experiment was conducted to study the diversity in growth parameters and alkaloid production between diploidy and tetra ploidy levels of Datura stramonium and Datura innoxia plants. Increases in plant height.

Significance of Myelodysplasia‐Related Mutations and the Genetic Landscape of Acute Leukemias of Ambiguous Lineage

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 3, Page 512-520, June 2026.
ABSTRACT The recent fifth edition WHO classification and ICC classification systems have moved further toward genetically defined classifications of acute leukemias. Both now recognize myelodysplasia‐related (MR) mutations as defining of MDS‐related AML (AML‐MR).

Evidence for degenerate tetraploidy in bdelloid rotifers [PDF]

open access: yesProceedings of the National Academy of Sciences, 2008
Rotifers of class Bdelloidea have evolved for millions of years apparently without sexual reproduction. We have sequenced 45- to 70-kb regions surrounding the four copies of the hsp82 gene of the bdelloid rotifer Philodina roseola , each of which is on ...

Induction of putative tetraploid larvae and analysis of unfertilized egg storage for burbot (Lota lota)

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Burbot (Lota lota) are a promising candidate for commercial aquaculture production. Methods for captive culture are well understood, the species is highly regarded for its muscle, roe, liver, and skin, and its resistance to many salmonid pathogens coupled with the species' affinity to trout‐like water quality conditions make burbot an ...

A Reevaluation of Tetraploidy in the Alzheimer’s Disease Brain [PDF]

open access: yesNeurodegenerative Diseases, 2009
Alzheimer’s disease (AD) is characterized by extensive neuronal death in distinct brain regions, including the frontal cortex and hippocampus, although the specific mechanisms of neuronal degeneration in AD remain a topic of intense scientific pursuit.

CHROMOSOME NUMBERS OF CHILEAN PTERIDOPHYTES: FIRST CONTRIBUTION NUMEROS CROMOSOMICOS DE PTERIDOFITOS CHILENOS: PRIMERA CONTRIBUCION

open access: yesGayana: Botanica, 2006
Mitotic chromosome counts in Chilean pteridophytes confirm the diploidy described for Equisetum L. (2n = 216) and Blechnum L. (2n = 66), as well as the tetraploidy of Asplenium L. (2n = 144). Megalastrum spectabile (Kaulf.) A.R.Sm.

DNA lesions induced by replication stress trigger mitotic aberration and tetraploidy development. [PDF]

open access: yesPLoS ONE, 2010
During tumorigenesis, cells acquire immortality in association with the development of genomic instability. However, it is still elusive how genomic instability spontaneously generates during the process of tumorigenesis.

Target Capture Sequencing Provides Insights Into Hybridogenetic Water Frogs

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The genomics of European frogs of the genus Pelophylax are intriguing due to their propensity to hybridise, the prevalence of polyploidy, and the unusual hemiclonal hybridogenetic complexes formed in many populations. This study examines the use of target capture sequencing using the Frog Cap bait set to investigate these complex systems.

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.

Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]

open access: yesPLoS Genetics, 2016
Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...
