Polyploidy in Gymnosperms: Revisited
, 2005 There are only a few natural polyploids in gymnosperms. These have been reported in Ephera spp. (Gnetales), and Juniperus chinensis ‘Pfitzeriana’ (2n = 4x = 44), Fitzroya cupressoides (2n = 4x = 44), and the only hexaploid conifer Sequoia sempervirens ...

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.

, 2016 A team of three scientists from Kansas State University, Michigan State University and the Desert Botanical Garden are investigating polyploidy (the condition of having more than one set of chromosomes) and diversity in the plant genus Phlox ...

Mechanisms of Thrombocytosis in Iron‐Deficiency Anemia
European Journal of Haematology, EarlyView.ABSTRACT Iron‐deficiency anemia is frequently accompanied by reactive thrombocytosis, yet the mechanisms underlying this association remain incompletely understood. Beyond impaired erythropoiesis, iron availability has emerged as an active regulator of hematopoietic lineage decisions.

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

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.

The FEBS Journal, EarlyView.DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Polyploidy and ecological adaptation in wild yarrow
, 2011 Chromosome evolution in flowering plants is often punctuated by polyploidy, genome duplication events that fundamentally alter DNA content, chromosome number, and gene dosage.

Journal of Integrative Plant Biology, EarlyView.In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.
