Are tetraploids more successful? Floral signals, reproductive success and floral isolation in mixed-ploidy populations of a terrestrial orchid [PDF]

open access: yes, 2017
Background and Aims Polyploidization, the doubling of chromosome sets, is common in angiosperms and has a range of evolutionary consequences. Newly formed polyploid lineages are reproductively isolated from their diploid progenitors due to triploid ...

Polyploidy-mediated resilience in hepatic aging: molecular mechanisms and functional implication

open access: yesEgyptian Liver Journal
Background Polyploidization, a process where cells acquire additional chromosome sets, is a unique characteristic of hepatocytes. This process has been increasingly recognized as an adaptive mechanism for maintaining liver function during aging, a period

Oryzalin-induced polyploidy in Vanda limbata (Blume): Phenotypic assessment

open access: yesActa Biochimica Indonesiana
Background: Vanda limbata is a natural orchid species found on Java Island, commonly known as V. limbata 'Jawa.' Enhancing plant vigor is essential to increase its potential as an ornamental plant, with one promising approach being induced polyploidy ...

The polyploid continuum and the landscape of polyploid genomic variation

open access: yesAmerican Journal of Botany
Abstract Polyploid research has traditionally distinguished between autopolyploids and allopolyploids on the basis of evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis. It has long been recognized, however, that a binary classification does not accurately reflect the complexity and diversity ...

Design and construction of a new Drosophila species, D.synthetica, by synthetic regulatory evolution [PDF]

open access: yes, 2011
Here, I merge the principles of synthetic biology^1,2^ and regulatory evolution^3-11^ to create a new species^12-15^ with a minimal set of known elements.
