Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

open access: yesAdvanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...

Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

open access: yes, 2015
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown.

Adiponectin Assists Thrombopoietic Agents in ITP Treatment by Enhancing Myosin‐9/Rab6A‐Mediated Trafficking of c‐Mpl in MKs

open access: yesAdvanced Science, EarlyView.
This study revealed that adiponectin facilitates the therapeutic efficiency of thrombopoietic agents by stimulating the membrane trafficking of c‐Mpl in MKs, which provides a point for ITP therapy. Moreover, a novel c‐Mpl trafficking mechanism based on the Myosin‐9/Rab6A complex is constructed. These findings provide new insights into the applicability

Resistance to frost and tuber soft rot in near-pentaploid Solanum tuberosum - S. commersonii hybrids [PDF]

open access: yes, 2007
The objectives of the present study were to evaluate the tolerance to low temperatures and tuber soft rot in sexual near-pentaploid hybrids between incongruent 2x (1EBN) Solanum commersonii (CMM) and 4x (4EBN) S. tuberosum (TBR). For freezing resistance,

Ploidy and the Causes of Genomic Evolution [PDF]

open access: yesJournal of Heredity, 2009
Genomes vary dramatically in size and in content. This variation is driven in part by numerous polyploidization events that have happened over the course of eukaryotic evolution. Experimental evolution studies, primarily using the yeast Saccharomyces cerevisiae, provide insights into the immediate fitness effects of ploidy mutations, the ability of ...

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.

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.

Large‐Scale Production of Transfusion‐Ready Red Blood Cells From Induced Pluripotent Stem Cells

open access: yesAdvanced Science, EarlyView.
A scalable, dynamic culture system is developed to produce red blood cells from induced pluripotent stem cells. It achieves high yields with up to 70% enucleation, not previously shown in dynamic systems, overcoming key limitations and enabling large‐scale production.

Size Polymorphism and Fluctuating Asymmetry of Artemia (Branchiopoda: Anostraca) Populations from the Crimea [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2017
Fluctuating asymmetry (FA) of animals as a measure of ontogenetic stability is widely used in environmental bioindication. Environmental stress leads to increased levels of FA within populations.
