The large fraction of transcripts with no hits appeared to be mostly due to transcript contigs from highly divergent UTR regions; examination of a number of these transcripts revealed that they are non-coding and map to the ends of genes from the H. melpomene genome [ 36].
The reconstructed phylogeny obtained revealed two highly divergent clades -one was mostly composed of sequences sampled in M. galloprovincialis populations (the B clade in Figure 4) and the other was exclusively composed of sequences sampled in M. edulis populations (the A clade).
Since protein-coding genes mostly arise from previous ones during evolution, even highly divergent coding sequences may harbour ancient footprints of common ancestral proteins to be found among the millions of proteins available in databases.
Whereas the microRNA precursors at this locus mostly belong to large sequence families, the mature microRNAs sequences are highly divergent.
For example, structural group 2 consists mostly of cyanobacterial sequences with similar RTs, but also includes other elements, e.g. from Haliscomenobacter, which have highly divergent RTs (Additional file 4).
But they offer highly divergent and often mutually exclusive ideas about how.
Our results explain the highly divergent models from previous structural studies.
Gomes, D. et al. Aquaporins are multifunctional water and solute transporters highly divergent in living organisms.
It also shows that the same gene can repeatedly underlie pattern evolution across highly divergent lineages.
However the reception to these groups' claims of reparations has been highly divergent.
