Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Tropical Africa is home to an astonishing biodiversity occurring in a variety of ecosystems.

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 …

Synthetic polyploids have been extensively studied for breeding in the last decade.
However, the use of such genotypes at the agronomical level is still limited. Polyploidization …

Whole‐genome duplication (WGD) is believed to increase the chance of adaptation to a new
environment. This conjecture may apply particularly well to new environments that are not …

Polyploidy, or genome doubling, has occurred repeatedly through plant evolution. While
polyploid plants are used extensively in agriculture and horticulture, they have so far found …

Gene duplication is a universal biological phenomenon that drives genomic variation and
diversity, plays a crucial role in plant evolution, and contributes to innovations in genetic …

The potential role of whole genome duplication (WGD) in evolution is controversial.
Whereas some view WGD mainly as detrimental and an evolutionary 'dead end', there is …

The Eurasian steppes occupy a significant portion of the worldwide land surface and their
