Polyploidy: pitfalls and paths to a paradigm

DE Soltis, CJ Visger, DB Marchant… - American journal of …, 2016 - Wiley Online Library
Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Speciation by genome duplication: Repeated origins and genomic composition of the recently formed allopolyploid species Mimulus peregrinus

M Vallejo-Marín, RJA Buggs, AM Cooley, JR Puzey - Evolution, 2015 - academic.oup.com
Whole genome duplication (polyploidization) is a mechanism of “instantaneous” species
formation that has played a major role in the evolutionary history of plants. Much of what we …

Homoeologous chromosome pairing across the eukaryote phylogeny

AL Grusz, EM Sigel, C Witherup - Molecular Phylogenetics and Evolution, 2017 - Elsevier
During the past quarter century, molecular phylogenetic inferences have significantly
resolved evolutionary relationships spanning the eukaryotic tree of life. With improved …

Evidence of genomic exchanges between homeologous chromosomes in a cross of peanut with newly synthetized allotetraploid hybrids

JR Nguepjop, HA Tossim, JM Bell, JF Rami… - Frontiers in plant …, 2016 - frontiersin.org
Cultivated peanut and synthetics are allotetraploids (2 n= 4 x= 40) with two homeologous
sets of chromosomes. Meiosis in allotetraploid peanut is generally thought to show diploid …

Preferential Disomic Segregation and C. micrantha/C. medica Interspecific Recombination in Tetraploid 'Giant Key' Lime; Outlook for Triploid Lime Breeding

D Ahmed, F Curk, JC Evrard, Y Froelicher… - Frontiers in plant …, 2020 - frontiersin.org
The triploid 'Tahiti'lime (C. x latifolia (Yu. Tanaka) Tanaka) naturally originated from a merger
between a haploid ovule of lemon (C. x limon (L.) Burm) and a diploid pollen from a …

Patterns of genomic variation reveal a single evolutionary origin of the wild allotetraploid Mimulus sookensis

MR Whitener, H Mangelson, AL Sweigart - Evolution, 2024 - academic.oup.com
Polyploidy occurs across the tree of life and is especially common in plants. Because newly
formed cytotypes are often incompatible with their progenitors, polyploidy is also said to …

Partial interfertility between independently originated populations of the neo-allopolyploid Mimulus peregrinus

M Vallejo-Marin, M Quenu, S Ritchie… - Plant Systematics and …, 2017 - Springer
The reduction in genetic diversity in polyploid lineages, formed from whole-genome
duplication of a few individuals, can affect their long-term evolutionary potential. Because …
