Mechanisms of Thrombocytosis in Iron‐Deficiency Anemia

open access: yesEuropean 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.

Does polyploidy facilitate long-distance dispersal? [PDF]

open access: yes, 2014
Background and AimsThe ability of plant lineages to reach all continents contributes substantially to their evolutionary success. This is exemplified by the Poaceae, one of the most successful angiosperm families, in which most higher taxa (tribes ...

On the quest to study polyploidy in cyanobacteria [PDF]

open access: yes
This thesis investigates the nuanced interplay between polyploidy and evolvability in prokaryotes, with a focus on Synechocystis PCC 6803. Traditionally thought to be rare in prokaryotes, polyploidy has been identified across diverse bacterial and ...

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

open access: yesThe 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 ...

Marigold Cell Size and Polyploidy [PDF]

open access: yes, 2004
Most animals are diploid, having one set of chromosomes from the male and one from the female. Polyploid animals, with the exception of some frogs and fish, are usually aborted or die immediately after birth (Gardner et al., 1991).

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

The host range paradox of Meloidogyne incognita: a physiological and transcriptomic analysis of nine susceptible interactions across six plant orders

open access: yesNew Phytologist, EarlyView.
Phylogenetic distance of host does not explain phenotypic differences of Meloidogyne incognita parasitism at 25 dpi. Summary The plant–parasitic nematode Meloidogyne incognita is the pathogen with the broadest host range among all known biotrophic interactions.

Evolutionary Innovation by Polyploidy [PDF]

open access: yes
The preferred conditions for evolutionary innovation is a fundamental question, but little is known, in part because the question involves rare events. We focused on the potential role of polyploidy in the evolution of novel traits.

Reticulate allopolyploidy and subsequent dysploidy drive evolution and diversification in the cotton family

open access: yesNature Communications
Polyploidy and subsequent post-polyploid diploidization (PPD) are key drivers of plant genome evolution, yet their contributions to evolutionary success remain debated.

Ecological and evolutionary implications of hybridization, polyploidy and apomixis in angiosperms

open access: yesBotan‪ical Sciences
Hybridization, polyploidy, and apomixis are related to the diversification of angiosperms, generating complex taxonomic relationships between species. Despite the differences in the frequencies of these phenomena, apomixis, the asexual seed production ...
