Analysis of variation for apomictic reproduction in diploid Paspalum rufum [PDF]
, 2014 Background and Aims: The diploid cytotype of Paspalum rufum (Poaceae) reproduces sexually and is self-sterile; however, recurrent autopolyploidization through 2n + n fertilization and the ability for reproduction via apomixis have been documented in one ...

Evolutionary history of Hypericum perforatum L. [PDF]
, 2011 The genus Hypericum is a highly diverse group of about 500 species. Among the Eurasian taxa, Hypericum perforatum L. and H. maculatum Crantz are representative examples with a largely overlapping distribution area in Central Europe.

Evolutionary history of an Alpine Archaeognath (Machilis pallida): Insights from different variant
Ecology and Evolution, 2023 Reconstruction of species histories is a central aspect of evolutionary biology. Patterns of genetic variation within and among populations can be leveraged to elucidate evolutionary processes and demographic histories.

Chromosome duplication in Brachiaria (A. Rich.) Stapf allows intraspecific crosses [PDF]
Crop Breeding and Applied Biotechnology, 2009 Brachiaria decumbens cv. Basilisk is the single most important forage grass used for pastures in the tropics.Breeding to produce improved cultivars has been impossible until now due to the lack of compatible sexual ecotypes. Thispaper reports the success

Asexual Reproduction Does Not Apparently Increase the Rate of Chromosomal Evolution: Karyotype Stability in Diploid and Triploid Clonal Hybrid Fish (Cobitis, Cypriniformes, Teleostei). [PDF]
PLoS ONE, 2016 Interspecific hybridization, polyploidization and transitions from sexuality to asexuality considerably affect organismal genomes. Especially the last mentioned process has been assumed to play a significant role in the initiation of chromosomal ...

Stochastic changes affect Solanum wild species following autopolyploidization [PDF]
, 2013 Polyploidy is very common within angiosperms, and several studies are in progress to ascertain the effects of early polyploidization at the molecular, physiological, and phenotypic level.

Plants, 2023 The remarkable species diversity of the genus Sorbus is a result of polyploidization and frequent hybridization between interacting species of different cytotypes. Moreover, hybridization is possible between several parental taxa.

Recombination suppression in plant adaptation and speciation
New Phytologist, EarlyView.Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...
