Estimation of polyploidy levels in Dianthus Germplasms by Flowcytometry [PDF]
, 2002 We tried to estimate the polyploidy levels of Dianthus germplasms preserved in National Institute of Floricultural Science by flowcytometry. The nuclear DNA relative values of them were distributed into three kinds of discontinuous groups which might ...

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots
Environmental Toxicology, EarlyView.ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Transcriptome of Xenopus andrei, an octoploid frog, during embryonic development
Data in Brief, 2018 Although polyploidy occurs throughout the fish and amphibian lineages, the Xenopus genus exhibits a high incidence of polyploidy, with 25 out of the 26 known species being polyploid. However, transcriptomic information is currently available for only one

Journal of Experimental Biology, 1924 ABSTRACT By polyploidy is meant an increase in the number of sets of chromosomes in a plant or animal. The bodies of animals and of the higher plants normally contain two sets of chromosomes, one derived from each parent. In ordinary sexual reproduction this number is reduced to one half in the maturation of the germ cells, and the ...

Integrative Zoology, EarlyView.Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...

Andrology, EarlyView.ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

Regulatory Mechanisms of Cell Polyploidy in Insects
Frontiers in Cell and Developmental Biology, 2020 Polyploidy cells undergo the endocycle to generate DNA amplification without cell division and have important biological functions in growth, development, reproduction, immune response, nutrient support, and conferring resistance to DNA damage in animals.

Cancer Science, EarlyView.A whole‐exome sequencing–based mutational signature biomarker (MSBM) identified an HRD‐enriched population in advanced ovarian cancer. In a phase II trial, olaparib maintenance suggested clinically meaningful PFS benefit without bevacizumab, supporting MSBM as a complementary HRD assessment approach.

Biological ControlParasitoid wasps are haplodiploid insects, but polyploidy (diploid males, triploid females) occurs for many species. In biological control, polyploidy may have beneficial effects on desirable biological related traits.

Karyotype analysis in 19 families from the Qinghai–Tibetan Plateau and its evolution implications
Caryologia, 2022 The chromosome numbers and karyotypes of 79 species and accessions from 19 plant families growing on the Qinghai–Tibetan Plateau were investigated. For 31 species, we provided first insights into their chromosomal numbers and karyotypic characteristics ...
