It could still be that a majority of segmental duplications occurred in a short time interval in the common ancestor of all three Phytophthora species, but this scenario is certainly much less parsimonious than a single WGD.
Direct comparison of two Mb-sized regions of the B and D genomes of bread wheat revealed similar rates of non-collinear gene insertion in both genomes with a majority of gene duplications occurring before their divergence.
We have performed a direct comparison of two Mb-sized regions of the B and D genomes of bread wheat and revealed similar rates of non-collinear gene insertion in both genomes with a majority of gene duplications occurring before their divergence.
However a majority of the duplicates studied were not the result of polyploidization, but of other, smaller-scale duplication events.
However, a majority of CNVRs associated with segmental duplications (82%) are known ones, which agrees with previous studies.
These results imply that the majority of duplication events happened dispersedly.
The majority of duplication events that lead to PTLS are recurrent (either common or uncommon) and are mediated by non-allelic homologous recombination involving LCRs.
This implies perhaps the majority of duplication events in Group I took place more recently than those in Groups II and III did.
In these arrays, a majority of the genes were derived from duplications occurring after the GA split but were shared between spruce and pine, indicating from the perspective of geological time that expression divergence may occur quite rapidly after gene duplication [ 51].
Despite a majority of these genes have arisen from segmental duplication events, the others were located either on non-duplicated blocks or on not-yet assembled scaffolds.
