Palaeoploidizations
WebOct 16, 2024 · 1 Introduction. After dispersal out of South America and into Africa during the mid-Eocene, four nested lineages of Asteraceae Bercht. & J. Presl. experienced … Paleopolyploidy is the result of genome duplications which occurred at least several million years ago (MYA). Such an event could either double the genome of a single species (autopolyploidy) or combine those of two species (allopolyploidy). Because of functional redundancy, genes are rapidly silenced or … See more Ancient genome duplications are widespread throughout eukaryotic lineages, particularly in plants. Studies suggest that the common ancestor of Poaceae, the grass family which includes important crop species such as … See more Paleopolyploidization events lead to massive cellular changes, including doubling of the genetic material, changes in gene expression and increased cell size. Gene loss … See more The hypothesis of vertebrate paleopolyploidy originated as early as the 1970s, proposed by the biologist Susumu Ohno. He reasoned that the vertebrate genome could not achieve its complexity without large scale whole-genome duplications. The … See more • Adams KL, Wendel JF (April 2005).

Paleopolyploidy can be identified as massive gene duplication at one time using a See more There are two major divisions of polyploidy, allopolyploidy and autopolyploidy. Allopolyploids arise as a result of the hybridization of two related species, while autopolyploids … See more • Gene duplication • Genomics • Karyotype • Ploidy See more
