Pairwise Linkage Disequilibrium Estimation for Polyploids
bioRxiv, 2020 Many tasks in statistical genetics involve pairwise estimation of linkage disequilibrium (LD). The study of LD in diploids is mature. However, in polyploids, the field lacks a comprehensive characterization of LD.

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.

Polyploids increase overall diversity despite higher turnover than diploids in the Brassicaceae
Proceedings of the Royal Society B, 2020 Although polyploidy is widespread across the plant Tree of Life, its long-term evolutionary significance is still poorly understood. Here, we examine the effects of polyploidy in explaining the large-scale evolutionary patterns within angiosperms by ...

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 ...

Genes, 2020 Floral organ size, especially the size of the corolla, plays an important role in plant reproduction by facilitating pollination efficiency. Previous studies have outlined a hypothesized organ size pathway. However, the expression and function of many of

Number of nucleoli in diploids and polyploids of the genus Achillea L.
Acta Societatis Botanicorum Poloniae, 2014 Nucleoli were counted in 9228 interphase nuclei of the apical root meristem of 40 Achillea L. taxa (di-, tetra-. hexa- and octoploids). It was established that the distribution of nucleoli number in an interphase nucleus can be used as a rough practical ...

Genotyping Polyploids from Messy Sequencing Data
Genetics, 2018 Gerard et al. highlight several issues encountered when genotyping polyploid organisms from next-generation sequencing data, including allelic bias, overdispersion, and outlying observations.

Characteristics of cytomixis in the pollen mother cells of green manure crop Sesbania cannabina [PDF]
Journal of Central European Agriculture, 2013 Cytomixis has been reported in many plant species, but there is no published report in Sesbania cannabina spp. The cytological stability of any plant is an important consideration in view of its extensive use in genetics and plant breeding programmes ...
