The Polyploid Continuum and Landscape of Polyploid Genomic Variation [PDF]

American Journal of Botany
Polyploid research has traditionally distinguished between autopolyploids and allopolyploids based on evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis.

The ecology of polyploid establishment and exclusion, with implications for polyploid biogeography

New Phytologist
The relationship between polyploid formation, triploid fitness and plant reproduction has been studied for over a century, and uniparental reproduction has long been recognized to play a crucial role in polyploid establishment. Yet, we lack a synthesized

Priors for Genotyping Polyploids [PDF]

Bioinformatics, 2019
Abstract Motivation Empirical Bayes techniques to genotype polyploid organisms usually either (i) assume technical artifacts are known a priori or (ii) estimate technical artifacts simultaneously with the prior genotype distribution.

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,

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species [PDF]

, 2011
Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...

Balancing gain and diversity: Optimal contribution selection for sustainable genetic improvement in sugarcane. [PDF]

Plant Genome
Abstract Sugarcane (Saccharum spp. hybrids), the source of ∼80% of the worlds sugar, has experienced a plateau in genetic improvement over recent decades. This stagnation is largely due to the crop's complex polyploid genome and long breeding cycles, which limit the efficiency of traditional selection methods.

Inference of haplotypic phase and missing genotypes in polyploid organisms and variable copy number genomic regions [PDF]

, 2008
Background: The power of haplotype-based methods for association studies, identification of regions under selection, and ancestral inference, is well-established for diploid organisms.

Ecological opportunity and the onset of polyploid niche expansion waves. [PDF]

Proc Natl Acad Sci U S A
Polyploidy, the presence of more than two sets of chromosomes, has evolved many times across the tree of life, yet we still do not know why some polyploid lineages persist while most go extinct.

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...
