[HTML][HTML] Plant speciation through chromosome instability and ploidy change: cellular mechanisms, molecular factors and evolutionary relevance
N De Storme, A Mason - Current Plant Biology, 2014 - Elsevier
Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Patterns, mechanisms, and consequences of homoeologous exchange in allopolyploid angiosperms: a genomic and epigenomic perspective
Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …

Polyploidy and novelty: Gottlieb's legacy
Nearly four decades ago, Roose & Gottlieb (Roose & Gottlieb 1976 Evolution 30, 818–
830.(doi: 10.2307/2407821)) showed that the recently derived allotetraploids Tragopogon …

[HTML][HTML] The role of genomic structural variation in the genetic improvement of polyploid crops
Many of our major crop species are polyploids, containing more than one genome or set of
chromosomes. Polyploid crops present unique challenges, including difficulties in genome …

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

The potential of genomics in plant systematics
Next‐generation sequencing (NGS) has revolutionized molecular systematics as well as
population and conservation genetics. It is now possible to obtain enormous amounts of …

[HTML][HTML] Revisiting meiosis in sugarcane: chromosomal irregularities and the prevalence of bivalent configurations
MLC Vieira, CB Almeida, CA Oliveira… - Frontiers in …, 2018 - frontiersin.org
Traditional sugarcane cultivars (Saccharum officinarum) proved highly susceptible to
diseases, and this led breeders to progress to interspecific crosses resulting in disease …

Transgenerationally precipitated meiotic chromosome instability fuels rapid karyotypic evolution and phenotypic diversity in an artificially constructed allotetraploid …
Although a distinct karyotype with defined chromosome number and structure characterizes
each biological species, it is intrinsically labile. Polyploidy or whole-genome duplication has …
