Haplotype-resolved autotetraploid genome of Dioscorea nipponica provides insights into recent polyploidization, metabolic rewiring, and environmental adaptation. [PDF]

Plant J
SUMMARY Whole‐genome duplication (WGD, or polyploidization) is a major evolutionary force in plants, yet the genomic, transcriptional, and metabolic consequences of autopolyploidy remain less understood than those of allopolyploidy. Dioscorea nipponica, a medicinal species producing diosgenin‐type steroidal saponins, harbors both diploid and ...

Molecular mechanisms underlying seed enlargement mediated by seed coat development in autotetraploid castor bean. [PDF]

Plant J
SUMMARY Polyploids, particularly synthetic lines, often produce larger seeds than their diploid progenitors. However, little is known regarding the role of seed coat development in the larger seeds formation in polyploid plants. Here, we investigated the cellular and molecular basis by which seed coat development mediates seed enlargement in the ...

Phenotypic and Metabolic Variations Induced by Autopolyploidization in Chinese Jujube Cultivars [PDF]

Plants
Autopolyploidization is critical to plant evolution and breeding, but systematic studies on its effects in woody plants remain limited. To address this gap, a systematic investigation covering autopolyploidization-induced variations in two autotetraploid

Converging GWAS and Genome Editing Decrypts MsCBF8-MsGolS2 Regulatory Module for Drought Tolerance Without Yield Penalty in Medicago sativa. [PDF]

Plant Biotechnol J
ABSTRACT Drought constitutes a major abiotic stress limiting alfalfa productivity. To elucidate the genetic basis of drought tolerance, a genome‐wide association study (GWAS) was conducted in alfalfa, which identified a CBF/DREB1 family transcription factor designated MsCBF8.

The Association Between DNA Methylation and Three-Dimensional Genome During Whole Genome Doubling in Arabidopsis thaliana [PDF]

Plants
Whole genome doubling (WGD) triggers profound genomic and epigenetic reorganization, yet the functional dynamics of DNA methylation during this process remain incompletely resolved.

Chromosome-scale and haplotype-resolved genome assembly of the autotetraploid Misgurnus anguillicaudatus [PDF]

Scientific Data
In nature, diploids and tetraploids are two common types of polyploid evolution. Misgurnus anguillicaudatus (mud loach) is a remarkable fish species that exhibits both diploid and tetraploid forms.

Extending Coalescent Theory to Autotetraploids [PDF]

Genetics, 2012
Abstract We develop coalescent models for autotetraploid species with tetrasomic inheritance. We show that the ancestral genetic process in a large population without recombination may be approximated using Kingman’s standard coalescent, with a coalescent effective population size 4N.

Autotetraploidization Gives Rise to Differential Gene Expression in Response to Saline Stress in Rice

Plants, 2022
Plant polyploidization represents an effective means for plants to perpetuate their adaptive advantage in the face of environmental variation. Numerous studies have identified differential responsiveness to environmental cues between polyploids and their
