A Role for Ploidy in Heart Regeneration [PDF]

open access: yesDevelopmental Cell, 2018
There is mounting circumstantial evidence that ploidy, a cell's relative DNA content, is in part responsible for the differential cardiac regenerative capacity observed between regenerative and non-regenerative organisms. In this issue of Developmental Cell, González-Rosa et al.

Genomic and Cis‐Regulatory Basis of a Plastic C3‐C4 Photosynthesis in Eleocharis Baldwinii

open access: yesAdvanced Science, EarlyView.
The sedge Eleocharis baldwinii remarkably switches between C3‐like and C4‐like photosynthesis in response to environmental conditions. Combining gap‐free genome assembly with single‐cell multi‐omics, this study uncovers how subgenome dominance and cell‐specific cis‐regulation enable C4 photosynthesis.

Variation of specific morphological traits and ploidy level of five "aegilops" l. species in Morocco [PDF]

open access: yes, 2003
Variation of specific morphological traits and ploidy level of five Aegilops L. species in Morocco.The genus Aegilops L. represents an important natural source of useful genes for wheat breeding, with particular emphasis on biotic and abiotic stress ...

Efficient Generation of Megakaryocyte Progenitors and Platelets From HSPCs via JAK2/STAT3 Signaling

open access: yesAdvanced Science, EarlyView.
This research presents a novel strategy employing the VGM cocktail, which combines HES7 overexpression with HDAC inhibitor and GABA, to enhance platelet production from hematopoietic stem and progenitor cells by promoting megakaryocyte progenitor (MkP) generation.

Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]

open access: yes, 2020
Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

Polyploid superficial cells that maintain the urothelial barrier are produced via incomplete cytokinesis and endoreplication [PDF]

open access: yes, 2018
Summary: The urothelium is an epithelia barrier lined by a luminal layer of binucleated, octoploid, superficial cells. Superficial cells are critical for production and transport of uroplakins, a family of proteins that assemble into a waterproof ...

Subgenome Dominance in Allotetraploid Actinidia valvata Regulates RNA m6A Modification for Waterlogging Tolerance

open access: yesAdvanced Science, EarlyView.
The waterlogging tolerance of allotetraploid Actinidia valvata is inherited from one of its diploid progenitors, which leads to subgenome expression dominance, mediated by complex mechanisms including altered chromatin accessibility and DNA methylation.

Outstanding intraindividual genetic diversity in fissiparous planarians (Dugesia, Platyhelminthes) with facultative sex.

open access: yes, 2019
Predicted genetic consequences of asexuality include high intraindividual genetic diversity (i.e., the Meselson effect) and accumulation of deleterious mutations (i.e., Muller’s Ratchet), among others.

Phylogenetic relationships and the identification of allopolyploidy in circumpolar Silene sect. Physolychnis

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Species complexes are groups of closely related species with ambiguous delimitation, often composed of recently diverged lineages. Polyploidization and uniparental reproduction (i.e., selfing and apomixis) can play important roles in the origin of species complexes. These complexes pose challenges for species‐based scientific questions,

Patient With Prolidase Deficiency due to an Homozygous PEPD Variant, Induced by Paternal Uniparental Isodisomy of Chromosome 19

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Uniparental disomy (UPD) is a rare phenomenon in which both copies of a chromosome are inherited from a single parent. This can lead to genomic imprinting disorders and recessive disorders due to the presence of recessive pathogenic variants in both alleles. Additionally, depending on the mechanisms by which UPD occurs, mosaic aneuploidies may
