If they are, the key question would be: is the great evolutionary distance that has so far prevented their discovery consistent with their being very early diverging from typical Omp85 or the result of secondary evolutionary degeneration?
The same study hypothesized that M. oryzae lineages adapted to different host plants have diverged with very limited gene flow, leading to a tree-like genealogy.
Model study systems would ideally include species that are firstly sympatric and secondly very recently diverged, with an effective mechanism of mating isolation.
The views were polarised, highlighting that undecided voters have two very different candidates, with diverging views and policies, from which to choose.
All trees show a close association between members of the Bovina subtribe, with all major lineages diverging very rapidly some 1 3 million years ago, which appears to be associated with climatic oscillations during the late Pleistocene [ 27, 28].
When looking at scatterplots (data not shown) there is a very uniform pattern, with no diverging groups at the extreme ends, but with larger possibility of variation in the middle.
Specifically, our data have revealed firstly, that the central segment of the mat chromosomes contains genes wherein alleles have markedly diverged, and secondly, that this region is flanked by regions with very low, or no, divergence.
With the exception of Monoiognosis, which has only very recently diverged into two species on Mauritius, further intra-generic splits occurred only in geographical isolation after colonisation of Réunion.
Thus, with increasingly diverging interpretations, it is sometimes very difficult to make a satisfactory decision on which model to choose, or indeed whether to pool the trials in a meta-analysis at all.
Some dubious hits including too highly diverged sequences and those with very short SET-domain-like sequences were removed.
