ANGIOSPERMS VS VERTEBRATE WGD. "Much of this disparity can be attributed to the different nature of plant vs. animal development vis-à-vis compensation for gene dosage. Subfunctionalization of gene duplicates has been shown to be a prominent molecular evolutionary force for coping with WGD in both flowering plants and ray-finned fish." (WGD = whole genome duplication). https://lnkd.in/eg_D7BR View in LinkedIn

EXCEPTIONAL STATUS. "Despite clear evidence for WGD underlying all vertebrates, many fewer lineage-specific polyploidy events have been detected than among angiosperms, which have a far shorter combined evolutionary history." (WGD = whole genome duplication). https://lnkd.in/eg_D7BR View in LinkedIn

EXPLOSIVE SPECIATION. "Nowhere else in the history of life is the influence of polyploidy more apparent as a possible diversifying force as it is among the angiosperms. Only the tetraploidization event in the stem lineage of ray-finned fish may come close, having potentially resulted in >20 000 living species." https://lnkd.in/eg_D7BR View in LinkedIn

HOTSPOT. "The Hawaiian flora has the highest incidence of polyploidy known, and most Hawaiian species are paleopolyploid, having evolved polyploidy prior to the dispersal of their ancestors to Hawaii." https://lnkd.in/eg_D7BR View in LinkedIn

POLYPLOIDY PUSH. "Given the many purported benefits of polyploidy and the suggested relationship of genome duplication to speciation, rates of diversification may be higher in polyploid lineages than in diploid groups (due either to increased rates of speciation, decreased rates of extinction, or both)." https://lnkd.in/eg_D7BR View in LinkedIn

DRAMATIC ROLE. "We emphasize that polyploidy, often referred to in the genomics literature as whole-genome duplication (WGD), has played a dramatic role in the diversification of most, if not all, eukaryotic lineages, perhaps most impressively within the angiosperms." (WGD = whole genome duplication). https://lnkd.in/eg_D7BR View in LinkedIn

EXPANDED QUESTION. "The question is no longer “What proportion of angiosperms are polyploid?”, but “How many episodes of polyploidy characterize any given lineage? and “Did specific genes resulting from genome duplication serve to fuel adaptive radiations?” https://lnkd.in/eg_D7BR View in LinkedIn

RESOLVING COMPLICATION. "In many lineages, the existence of WGD events, and the numbers of these events, remain unclear. Whether the vertebrate lineage had experienced two or three rounds of WGD was the subject of a long debate that was resolved only recently through a careful analysis of the synteny patterns of WGD paralogs."

COMPLICATING FACTOR. "WGDs are particularly widespread in the phylogeny of flowering plants, giving rise to large gene families and complicating comparative studies." (WGD = whole genome duplication). http://www.pnas.org/content/107/1/472.full View in LinkedIn

SPECIATION. "Reciprocal gene loss following a WGD can contribute to reproductive isolation through divergent resolution of duplicate copies, foreshadowing the diversification of species." (WGD = whole genome duplication). http://www.pnas.org/content/107/1/472.full View in LinkedIn
