Science China Life Sciences, 2012 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 ...

Priors for Genotyping Polyploids [PDF]
Bioinformatics, 2019 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 ...

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high-throughput RNA sequencing. [PDF]
Plant GenomeAbstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Paleo-Polyploidization in Lycophytes
Genomics, Proteomics & Bioinformatics, 2020 Abstract Lycophytes and seed plants constitute the typical vascular plants. Lycophytes have been thought to have no paleo-polyploidization although the event is known to be critical for the fast expansion of seed plants. Here, genomic analyses including the homologous gene dot plot analysis detected multiple paleo-polyploidization events,

Polyploidization and domestication [PDF]
SCIENTIA SINICA Vitae, 2021 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 ...

POLYPLOID INCIDENCE AND EVOLUTION [PDF]
Annual Review of Genetics, 2000 ▪ Abstract Changes in ploidy occurred early in the diversification of some animal and plant lineages and represent an ongoing phenomenon in others. While the prevalence of polyploid lineages indicates that this phenomenon is a common and successful evolutionary transition, whether polyploidization itself has a significant effect on patterns and rates ...

De novo construction of polyploid linkage maps using discrete graphical models [PDF]
, 2018 Linkage maps are used to identify the location of genes responsible for traits and diseases. New sequencing techniques have created opportunities to substantially increase the density of genetic markers.

Reproduction and Breeding, 2023 The kisspeptin system, which involves hypothalamic neuropeptides, plays pivotal roles in the regulation of teleost reproduction. A previous study suggested that the kiss2/kissr2 system in largemouth bass (Micropterus salmoides) was involved in regulating

Surviving a Genome Collision: Genomic Signatures of Allopolyploidization in the Recent Crop Species [PDF]
, 2017 Polyploidization has played a major role in crop plant evolution, leading to advantageous traits that have been selected by humans. Here, we describe restructuring patterns in the genome of Brassica napus L., a recent allopolyploid species.

3 tera-basepairs as a fundamental limit for robust DNA replication [PDF]
, 2020 10 p.-2 tab.In order to maintain functional robustness and species integrity, organisms must ensure high fidelity of the genome duplication process. This is particularly true during early development, where cell division is often occurring both rapidly ...
