Genetic relationships and polyploid origins in the Lippia alba complex
JML Lopes, HH de Carvalho, C Zorzatto… - American Journal of …, 2020 - Wiley Online Library
Premise Plant genomes vary in size and complexity due in part to polyploidization.
Latitudinal analyses of polyploidy are biased toward floras of temperate regions, with much …

Tragopogon pratensis: Multiple introductions to North America, circumscription, and the formation of the allotetraploid T. miscellus
Tragopogon (Asteraceae) includes two recently and repeatedly formed allopolyploids, T.
mirus and T. miscellus, both of which formed in western North America following the human …

Heritable alteration of DNA methylation induced by whole‐chromosome aneuploidy in wheat
Aneuploidy causes changes in gene expression and phenotypes in all organisms studied. A
previous study in the model plant Arabidopsis thaliana showed that aneuploidy‐generated …

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

Present‐day sympatry belies the evolutionary origin of a high‐order polyploid
Disentangling the evolutionary histories of polyploids, especially those with high ploidies,
can reveal fundamental processes in speciation. Despite occurring frequently during …

Karyotypic variation and pollen stainability in resynthesized allopolyploids Tragopogon miscellus and T. mirus
JP Spoelhof, M Chester, R Rodriguez… - American Journal of …, 2017 - Wiley Online Library
PREMISE OF THE STUDY: Polyploidy has extensively shaped the evolution of plants, but
the early stages of polyploidy are still poorly understood. The neoallopolyploid species …

The origin of allotetraploid Lepisorus inaequibasis (Polypodiaceae) and paternal bias in its morphology and abiotic niche
Lepisorus inaequibasis is thought to be of hybrid origin due to its leaf shape and sporangia
being intermediate between those of its putative progenitors. Subsequent molecular studies …

Trajectories of Homoeolog-Specific Expression in Allotetraploid Tragopogon castellanus Populations of Independent Origins
Polyploidization can have a significant ecological and evolutionary impact by providing
substantially more genetic material that may result in novel phenotypes upon which …

Karyotype evolution: concepts and applications
KFM de Resende - Chromosome structure and aberrations, 2017 - Springer
The karyotype is the characterization of number, size, and morphology of the set of
chromosomes of a species, as seen under the microscope. Studying the karyotypic evolution …

Multilocus phylogenetic reconstruction informing polyploid relationships of Aconitum subgenus Lycoctonum (Ranunculaceae) in China
Polyploidization has long been recognized as one of the most important driving forces of
plant evolution. Aconitum subgenus Lycoctonum (Ranunculaceae) has a wide distribution …
