Evolutionary variations generating phenotypic adaptations and novel taxa resulted from
complex cellular activities altering genome content and expression:(i) Symbiogenetic cell …

It is broadly assumed that polyploidy success reflects an increase in fitness associated with
whole‐genome duplication (WGD), due to higher tolerance to stressful conditions …

Polyploidy is widely recognized as a major evolutionary force in plants and has been
reported in the genus Lippia (Verbenaceae). Lippia alba, the most studied species, has …

Genome change does not occur accidentally. The conventional Modern Synthesis view of
gradual evolution guided solely by natural selection fails to incorporate many important …

Apomixis refers to a set of reproductive mechanisms that invariably rely on avoiding meiotic
reduction and fertilization of the egg cell to generate clonal seeds. After having long been …

Recent research suggests that the frequency of polyploidy may have been underestimated
in gymnosperms. One notable example is in the conifer genus Juniperus, where there are …

An ancient hexaploidization event in the most but not all Asteraceae plants, may have been
responsible for shaping the genomes of many horticultural, ornamental, and medicinal …

Polyploidization is an important source of variability for plant breeding. Polyploids are often
characterised by increased resistance to biotic and abiotic stresses. Since drought and …

Polyploids recurrently emerge in angiosperms, but most polyploids are likely to go extinct
before establishment due to minority cytotype exclusion, which may be specifically a …

Polyploidy, or whole genome duplication, has been an important feature of eukaryotic
evolution. This is especially true in flowering plants, where all extant angiosperms have …
