Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass
Long-term climate change and periodic environmental extremes threaten food and fuel security1 and global crop productivity2–4. Although molecular and adaptive breeding strategies can buffer the effects of climatic stress and improve crop resilience5 ...

Polyploids are organisms with three or more complete chromosome sets. Polyploidization is widespread in plants and animals, and is an important mechanism of speciation. Genome sequencing and related molecular systematics and bioinformatics studies on plants and animals in recent years support the view that species have been shaped by whole genome ...

Polyploidization and domestication [PDF]
Crop domestication is the process to domesticate and propagate wild plants into cultivated crops, and its essence is to purposefully preserve the genetic variation information on the genome through artificial selection. Domestication has played an important role in the origin and evolution of human farming civilization, and promoted the sustainable ...

Polyploidy has the potential to allow organisms to outcompete their diploid progenitor(s) and occupy new environments. Shark Bay, Western Australia, is a World Heritage Area dominated by temperate seagrass meadows including Poseidon's ribbon weed ...

GenomeScope 2.0 and Smudgeplot for reference-free profiling of polyploid genomes
An important assessment prior to genome assembly and related analyses is genome profiling, where the k-mer frequencies within raw sequencing reads are analyzed to estimate major genome characteristics such as size, heterozygosity, and repetitiveness ...

Learning to tango with four (or more): the molecular basis of adaptation to polyploid meiosis
Polyploidy, which arises from genome duplication, has occurred throughout the history of eukaryotes, though it is especially common in plants. The resulting increased size, heterozygosity, and complexity of the genome can be an evolutionary opportunity ...

Priors for Genotyping Polyploids [PDF]
AbstractMotivationEmpirical Bayes techniques to genotype polyploid organisms usually either (i) assume technical artifacts are knowna priorior (ii) estimate technical artifacts simultaneously with the prior genotype distribution. Case (i) is unappealing as it places the onus on the researcher to estimate these artifacts, or to ensure that there are no ...

Polyploidization and epigenetics [PDF]
The occurrence of polyploidy, or whole genome duplication, can result in instantaneous speciation. Because new polyploids are immediately reproductively isolated from their non-polyploid congeners, polyploidization has played an important role in the diversification of flowering plants and some vertebrates.
