Problematic octaploid forms and a new chromosome number in the genus Achillea L., 2n = 126
Acta Societatis Botanicorum Poloniae, 2014 Among the offspring of a problematic form of Achillea sp., a 2n = 126 seedling which probably arose as the result of fusion of unreduced octo- and hexaploid gametes (72 + 54) was found along with seedlings having an octaploid chromosome number (2n = 72).

A Reappraisal of Polyploidy Events in Grasses (Poaceae) in a Rapidly Changing World
Biology, 2022 Around 80% of megaflora species became extinct at the Cretaceous–Paleogene (K–Pg) boundary. Subsequent polyploidy events drove the survival of thousands of plant species and played a significant historical role in the development of the most successful ...

Polyploidization in Liver Tissue
The American Journal of Pathology, 2014 Polyploidy (alias whole genome amplification) refers to organisms containing more than two basic sets of chromosomes. Polyploidy was first observed in plants more than a century ago, and it is known that such processes occur in many eukaryotes under a variety of circumstances.

Polyploidization and domestication [PDF]
SCIENTIA SINICA Vitae, 2021 Crop domestication is the process to domesticate and propagate wild plants into cultivated crops, and its essence is to purposefully preserve the genetic variation information on the genome through artificial selection. Domestication has played an important role in the origin and evolution of human farming civilization, and promoted the sustainable ...

Impact of polyploidy on plant tolerance to abiotic and biotic stresses
Frontiers in Plant Science, 2022 Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an organism’s cells, is considered as a pivotal moving force in the evolutionary history of vascular plants and has played a major role in the domestication of ...
