We also report massive expression divergence among diploid congeners in a common environment and the manner in which these differences become reconciled in a nascent polyploid.
Black widow SSTs (with the exception of the spidroins) were almost exclusively paralogous with generally expressed transcripts, suggesting massive regulatory divergence after the duplication event.
These proteomes show a massive loss or divergence of human orthologs including developmental proteins (fig. 4 B and not shown).
However, given the massive loss (or divergence) of proteins noted in these three species, this conclusion should be confirmed by testing the proteomes of additional species to definitely sort out phylum-specific from lineage-specific events (see Discussion).
Comparative genomic analysis has revealed higher genetic divergence and massive gene loss within the ecdysozoan lineages.
We found that the O. sativa lineage appears to have recently experienced massive gene losses following divergence from its wild ancestor.
The data demonstrate massive, near-complete expression-level divergence among duplicates, consistent with regulatory neo- and/or subfunctionalization, and provide a genome-scale view of expression level evolution tracing to ancient polyploidy.
In any case, the possible massive losses or the high divergence of APC/C components both suggested that important changes have occurred relatively recently in these parasitic lineages, maybe as a consequence of their atypical cell division mechanism.
This has revealed a period of massive expansion of Class I receptors between the divergence of urochordates and vertebrates around 794 million years ago (MYA), and divergence of ray-finned and lobe-finned fishes some 476 MYA.
This system facilitates the stuffy of the effects of sequence divergence as it does not cause massive aneuploidy.
