New Phytologist, EarlyView.Ploidy level distributions and endoreduplication profiles in diploid and tetraploid Arabidopsis arenosa. Summary Endopolyploidy (within‐organism polyploidy) is an often‐beneficial aspect of development. But polyploids, which have a higher baseline genome content, have been reported to have less endoreduplication than diploid relatives. Why has remained

Polyploidy Phenomenon as a Cause of Early Miscarriages in Abortion Materials
, 2023 Objectives: Chromosomal abnormalities are an important cause of especially early miscarriages. The aim of this study was to analyze the chromosomal aberrations and determine the frequencies of numerical and structural chromosome abnormalities in ...

Assessing Future Maladaptation Risk in the Keystone Species Populus tremuloides [PDF]
Evol ApplABSTRACT Understanding the adaptive potential of widespread trees is critical for predicting species resilience under climate change and informing their conservation strategies. We assessed the genomic offset in Populus tremuloides Michx. (aspen) using 10,937 genotyping‐by‐sequencing derived, high‐quality SNPs from 891 individuals sampled across the ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Evolutionary Innovation by Polyploidy [PDF]
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.

Plant Biotechnology Journal, EarlyView.ABSTRACT Oleic acid (18:1), saturated fatty acid (SFA), and polyunsaturated fatty acid (PUFA) levels are important traits for storage stability and edibility. In this study, we aimed to develop high‐oleic soybean (Glycine max) by simultaneously targeting fatty acid desaturase 2 (FAD2) and fatty acyl‐ACP thioesterase B (FATB) gene families using CRISPR ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Despite the therapeutic importance of cannabinoids, the scarcity of gap‐free Cannabis genomes has limited the dissection of the genetic and genomic basis of cannabinoid biosynthesis and genome evolution. Here, we generated two haplotype‐phased, gap‐free, gold‐standard assemblies and used them to investigate post‐polyploid genome remodelling ...

Plant Breeding, EarlyView.ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Polyploidy and the Cellular and Areal Diversity of Rat Cortical Layer 5 Pyramidal Neurons
Cell Reports, 2017 In many species, polyploidy, in which an increase in nuclear DNA content is accompanied by an increase in cell size, contributes to cellular diversity.
