WebJun 1, 2024 · Analysis of the cucurbit genomes using this pipeline revealed an overlooked paleo-tetraploidization event, occurring ~100 MYA, in the common ancestor of … Paleopolyploidization events lead to massive cellular changes, including doubling of the genetic material, changes in gene expression and increased cell size. Gene loss during diploidization is not completely random, but heavily selected. Genes from large gene families are duplicated. On the other hand, … See more 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 ( See more Duplicated genes can be identified through sequence homology on the DNA or protein level. Paleopolyploidy can be identified as massive gene duplication at one time using a molecular clock. To distinguish between whole-genome duplication and a collection of (more … 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). "Polyploidy and genome evolution in plants". Current Opinion in Plant Biology. 8 (2): 135–41. 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 maize, rice, wheat, and sugar cane, shared … 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 arise from the duplication of a species' genome as a result of hybridization of two … See more • Gene duplication • Genomics • Karyotype • Ploidy See more
