For animals, an extra chromosome can result in major problems, but plants are another matter. Many plants can survive an extra copy of their entire genome (polyploidy), and this process often results ...

Researchers emphasize that polyploidy and the important role it has played, especially in plant evolution, would not have gained the recognition it deserves would it not have been for its staunch ...

The hepatocyte is a main contributor to liver functions, including in metabolic homeostasis, synthesis, storage, distribution, and detoxification of xenobiotic compounds. Hepatocyte polyploidization ...

Polyploidy is a state where a cell contains more copies of the genetic material than the usual "diploid" cell, which contains two copies. Polyploidy often occurs in human diseases and cancers, and its ...

Polyploidy, or whole-genome duplication (WGD), is usually an evolutionary dead end. Although polyploidy is a frequent and recurrent phenomenon, the number of WGDs that have become established in the ...

BLOOMINGTON, Ind. -- Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists from Indiana University ...

Scientists have long known that some cells in a given tissue undergo a process of duplicating their entire genome without dividing – a process called endopolyploidy, where cellular ploidy is the copy ...

Assistant Professor of Biology Vicki Losick admits she harbors a desire to change the world a little bit. “I want to make ‘polyploidy’ a household word,” Losick said in her Higgins Hall office, next ...
