Paleo-polyploidization in Lycophytes
Genomics, Proteomics & Bioinformatics, 2020 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.

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.

New Phytologist, 2021 SummaryPolyploidy is a dominant feature of extant plant diversity. However, major research questions, including whether polyploidy is important to long‐term evolution or is just ‘evolutionary noise’, remain unresolved due to difficulties associated with the generation and analysis of data from polyploid lineages.

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 ...

Megakaryocyte polyploidization: role in platelet production
Platelets, 2020 Mammal megakaryocytes (MK) undergo polyploidization during their differentiation. This process leads to a marked increase in the MK size and of their cytoplasm.

Dynamic hybridization between two spleenworts, Asplenium incisum and Asplenium ruprechtii in Korea
Frontiers in Plant Science, 2023 Natural hybridization between Asplenium incisum and A. ruprechtii has been observed in Northeast Asia and its allotetraploid species, A. castaneoviride, was reported.

Unreduced megagametophyte production in lemon occurs via three meiotic mechanisms, predominantly second-division restitution [PDF]
, 2017 Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties.
