High‐Contiguity Haplotype‐Resolved Genome Assembly of the Hexaploid Actinidia valvata Rootstock Sheds Light on Waterlogging Resistance Gene

open access: yesPlant 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 ...

Homoeologous nonreciprocal recombination in polyploid cotton

open access: yes, 2010
International audience• Polyploid formation and processes that create partial genomic duplication generate redundant genomic information, whose fate is of particular interest to evolutionary biologists.

Programmable Domestication: CRISPR, Pan‐Genomics and System Level Engineering for Next‐Generation Crops

open access: yesPlant Biotechnology Journal, EarlyView.
Conceptual overview of programmable de novo domestication from genetic diversity discovery to crop deployment. The framework connects diverse germplasm and genomic resources with three trajectory pathways. Adaptive Rescue, Agronomic Refinement and Novel Chassis defined by biological distance, engineering complexity and breeding objectives.

Genetic basis and breeding application of clonal diversity and dual reproduction modes in polyploid Carassius auratus gibelio

open access: yes, 2010
A unisexual species is generally associated with polyploidy, and reproduced by a unisexual reproduction mode, such as gynogenesis, hybridogenesis or parthenogenesis.

Converging GWAS and Genome Editing Decrypts MsCBF8‐MsGolS2 Regulatory Module for Drought Tolerance Without Yield Penalty in Medicago sativa

open access: yesPlant Biotechnology Journal, EarlyView.
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.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant 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.

Variation in nuclear genome size in a freshwater snail model system featuring a recent whole-genome duplication

open access: yesRoyal Society Open Science
Conspecifics often share—or are assumed to share—nuclear genome characteristics like nucleotide composition and genome size. These fundamental aspects of the nuclear genome can themselves be the object of natural selection. We here provide the first high-

A Century of Understanding and Harnessing Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

open access: yesPlant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Creating insect neopolyploid lines to study animal polyploid evolution [PDF]

open access: yes
Whole-genome duplication (polyploidy) poses many complications but is an important driver for eukaryotic evolution. To experimentally study how many challenges from the cellular (including gene expression) to the life history levels are overcome in ...
