Pegasoferae?

Can rare genomic events establish Pegasoferae?

Pegasoferae is a novel proposal using rare genomic events involving retroposon insertions to establish the phylogenetic ordering within Laurasiatheres, grouping bats, perissodactyls and carnivores to the exclusion of the other hoofed mammalian group, artiodactyls. Bats have been placed in many previous locations, notably in the Euarchonta wing (outgroup to primates). While that particular idea is clearly refuted by many lines of evidence, the proper placement of bats remains under discussion.

Rare genomic events may be more useful for this than maximal likelihood because the orders of Laurasiatheres may have diverged relatively rapidly. Retroposon events are so numerous per million years however that they may be able to resolve branching at these tight nodes. However they suffer from homoplasy in that separate insertion events from a given parental element can look very similar and because deletions over time (no selection for their retention) can cause their disappearance and so confusion with lineages that never had the insertion.

Qualifying retroposons need to be situated between two well-conserved flanking markers because orthology is otherwise difficult to decisively establish in intergenic regions. These markers ideally are no more than 1500bp apart to allow tiling of traces for species without assemblies (eg vicugna, pig, dolphin, macrobat in Laurasiatheres) and spanning PCR runs. Higher sampling density greatly enhances the ability to correctly infer the sequence of events.

Short coding indels in coding exons can also be phylogenetically informative. Here if the exon is otherwise quite conserved, the risk of homoplasy (recurrent events at the same or indistinguishably similar position) is fairly low. These events are inherantly rare first because conserved regions of a protein may not admit indels structurally (ie are inactivated) and second because the window of relevancy for a given tree topology issue may only be a small fraction of elapsed evolutionary time (eg 1 million year stem on a 85 myr branch).

Coding indels can exhibit the usual problems of lineage-sorting: two co-existing alleles at the time of speciation that resolve differently in descendent lineages. Insertions, while a third as common as deletions and so less likely to have arise multiple times, are more subject to subsequent confusing reversion; deletions are less likely to revert to ancestral length for lack of genetic mechanism. It goes without saying that indels from repetitive regions or in dna of anomalous composition are wholly unsuitable for taxonomic purposes.

Methods for re-analysis and supplementation of L1MA9 data

Nishihari et al located 4 retroposon insertion events that support Pegasoferae. In the ensuing 2-3 years, it has become possible to reinvestigate these events with additional species utilizing bioinformatic methods on the 10 available Laurasiathere genomes (not all of which will completely cover a given event).

This can be done fairly rapidly (though only a subset of the putatively informative L1MA9 insertions are analyzed here). First, the primers used by the Okada group are blatted into the UCSC genome browser of an appropriate species (dog). The reverse strand primer must be first reverse-complemented with the UCSC utilities tool for a single line of Blat output to span the region of interest.

In every case studied here, the L1MA9 elements lie within small introns of coding genes. That means typically 30-40 amino acids from each flanking exon are available to create reliable anchors for future blast searches at NCBI. Without these anchors, L1MA9 elements do not necessarily retrieve orthologous elements in other species via blast, for the reason that the active L1MA9 parent element may have spun off subsequent fragments that are closer in sequence.

Next, dna spanning the exons and their internal intron are collected from Laurasiatheres with UCSC genome browsers, notably dog, cat, horse and cow. This dna is then marked up for all retroposons using the RepeatMasker track. Here it is important to track orientation of the repeat element (letting the reading frame of the exons define the positive strand convention), the fragment coordinates relative to an idealized repeat of the given class in the underlying RepeatMasker library, and the percent identity to this element.

These three steps allow in-depth comparison of putatively orthologous retroposons, noting however in the case of L1MA9 elements that fragment coordinates are very similar in many thousands of these insertions due to the replication mechanism favoring distal fragments of similar lengths. Thus homoplasic events cannot truly be ruled out even upon this closer examination.

The comparative genomics is extended now to additional species using tblastn of the WGS contig division of GenBank. This target database stores 2x assemblies of species such as microbat, hedgehog, and shrew. The spanning contig GenBank entries are then uBlasted against the growing database of fiducial sequences to locate the exons and intervening sequence. The latter is most conveniently retrieved by screen-scraping of 6-frame translation, dropping out the alternate lines containing the amino acids.

The latter two species exons can sometimes be retrieved faster from the 28-species alignment track at UCSC -- genomic alignment provides more reliable orthologs -- some lineages could have idiosyncratic segmental duplications that could cause cross-matching. If the coding regions are evolving too fast, the whole enterprise becomes questionable. Another pitfall is paralogs. Here GeneSorter at the UCSC site can be consulted, at least for human, to rapidly examine the situation.

Next, the est_other and nr divisions of GenBank are probed to retrieve any data that might be available from non-genomic projects. Transcripts per se don't seem useful here (lack the intron of interest) yet they provide precise probes later of the trace archives for the given species.

Finally, the trace achives are consulted for residual species such as macrobat, vicugna, sheep, pig, and dolphin. Note too that contigs and genomes often leave out singleton traces so these species can be completed here as necessary. The approach here is to tile in from both directions extending the reliable exon matches (if any). Since the L1MA9 elements needed to occur in small introns given the Nishihari et al discovery approach, usually 3 traces suffice to tile the intron successfully.

Trace reads are inherently error-prone (hence the need for 6x coverage to obtain a reliable genomic assembly). However here it is unlikely that a whole L1MA9 element would be missing unless the species in question had two distinct alleles. In evaluating rare genomic events, it is important to check all high-quality covering traces to rule out such polymorphisms because these would seriously undercut the whole exercise.

After obtaining data from all available Laurasiatheres, the sequences are marked up with different colors for their various constituent elements as illustrated below. Note the fasta header can carry the exonic sequence as well as quantitative information about the repeat elements. By extracting header lines only, a simple flatfile database emerges suitable for making simple summary comparative diagrams/

Analysis of L1MA9 retroposon INT189

The phlogenetic distribution of the L1MA9 retroposon INT189 has been taken as evidence for bats being the immediate outgroup of horse + dog. That interpretation can be revisited using newly available genomes. Yet only two sequences representing perissodactyl and carnivore are at GenBank as cat assembly has a gap in the critical region. But other new data in 3 bats and 4 cetartiodactyls and 2 shrew/hedgehog confirm the lack of L1MA9 near the distal exon.

The trouble is a second L1MA9 element lies upstream of the MER58A middle marker. This is lacking in both carnivores. Evidently it was deleted in stem carnivore -- otherwise it would be providing evidence for carnivores being outgroup to cows + bats + horse. In short this single intron is providing 'support' for two contradictory topologies.

The sizes of many bat genomes have been experimentally determined: the 30-genus average of 2.6 gbp is about 500,000,000 bp less than human. Since bats in essence have the same 20,000 coding genes as other mammals, that discrepancy has to arise from less intronic and intergenic dna. Possibly bats had fewer active retroposing elements. Far more likely, bats they have an average number and the discrepancy arises from a faster rate of deletions than insertions.

Thus for taxonomically informative (ancestral laurasiathere) retroposons, many millions of deletion events have occured. Since the L1MA9 elements here are only 100bp or so, it would come as no surprise if a high percentage of the older relevent ones have experienced partial (or full) deletions making them unrecognizable with RepeatMasker.

Thus presence of a retroposon in a given orthologous position bat can be informative but absence is not so informative. INT189 is an absence. That one event isn't insufficient anyway to establish branching order. So bat/horse/carnivore tree topology remains unresolved. If horse is the outgroup to carnivore + bat -- and cow outgroup to all of these -- then hoofed animals are parsimoniously ancestral (rather than arising twice by convergent evolution) and bat and carnivore lost hooves (a bit unreasonable as dog and bats retain the ancestral 5 digits).

Analysis of L1MA9 retroposon INT283 within gene ZUBR1

This potentially informative retroposon insertion denoted INT283 conflicts with Pegasoferae topology. That is not a fatal flaw because a certain fraction of such events resolve anomalously via lineage-sorting after speciation.

Again, this presented a favorable annotation situation because the two flanking exons are well-conserved and the intonic distance is short at about 1500 bp. Using new genomic data, the species density can be brought up 10 Laurasiatheres, tiling traces in unassembled genomes as necessary. The conflict with Pegasoferae holds up even sampling at this greater taxonomic sampling depth: an orthologous L1MA9 is also missing in microbat, shrew, hedgehog but present with correct orientation and correct fragment coordinates in vicugna, pig, and dolphin.

It can always be asked whether this is the "same" L1MA9 in cetartiodactyls or merely a similar one from a separate insertion event of the active parental element. However pushing the putative event back to basal vicugna narrows the window for that. While this situation can be dismissed with an appeal to lineage-sorting (importantly 4 events support Pegasoferae versus this 1 conflict).

Deletion in bat could equally be argued, though located orthologous dna in macrobat now pushes that putative event back into the shorter stem window as well. Absence in bat is not especially informative given their genomes are greatly reduced in size relative to other placental mammals -- much of this loss would occur in intragenic dna which like much intergenic does not often experience selective pressure for retention.

Analysis of L1MA9 retroposon INT391

Extended validation of this L1MA9 insertion, which occurs in a short intron of the gene ACSL5, is feasible in May 2008 because of newly available genomes. elements. The basic technique consists of first establishing the comparative genomics of the two outside coding exons. These are needed to reliably probe contig assemblies and trace archives with tblastn and blastn respectively. A complete intron can often be obtained by tiling out to the center from the two ends. It is imperative to avoid paralogous exons in doing so.

In the case of INT391, dog, cat, horse, microbat, macrobat had the retroposon judging by location, fragment coordinates relative to the full length retroposon, and strand orientation relative to the coding exons (minus strand here). Cow, dolphin, pig, vicugna, and shrew did not have it. Since cetartiodacytl L1MA9s might have been interrupted by a later retroposon breaking the L1MA9 into two unrecognizable shorter pieces, it is necessary to remove other repeats and re-run RepeatMasker.

Despite more intensive phylogenetic sampling, INT391 continues to support Pegasoferae as Nishijimi et al originally stated. It should be noted that the MER-class retroposon, while not at issue here, exhibits the type of homoplasy that makes retroposons dicey as tree topology markers. Introns are often susceptible to multiple insertions of similar retroposons as well as to complicated patterns of micro deletions that prevent their recognition even if they aren't fully deleted.

Phylogenetically informative coding insertions and deletions

Mammalian genomes contain about 20,000 genes comprised of some 190,000 exons. Insertions and deletions (indels) accrue slowly in these exons over time as species diverge from one another. These supplement information that can be derived from amino acid substitution analysis. In some instances, the initial indel occurs and is fixed across a stem population (a stem is an interval of evolutionary time not giving rise to lineages surviving to the present day).

Such rare genomic events can be phylogenetically informative. However they are potentially subject to re-occurence and reversion in some descendent clades which could confuse the issue. For this reason, it is imperative to screen out indels in regions of dna prone to this type of event by virtue of their repetitive nature (conducive to repeated replication slippage) or compositional simplicity.

Lineage-sorting is another issue but provided the stem persisted long enough for informative indels to arise in adequate numbers, those of the true topology should significantly outnumber anomalies arising from the two alleles exisitng at the time of speciation sorting out differently in descendent clades. However in the situation when several mammalian orders arise over a very short period of time (in effect a polytomy) or when the speciation process itself is blurred by millions of years of hybridization or genetic mixing at population boundaries, the whole concept of discrete topological tree branching may be inapplicable.

Analysis of a potentially informative indel in CHML

A loss of one amino acid can be observed within an exon of the gene CHML in carnivores, bats, and horse but not in other Laurasiatheres (or other placental mammals. This gene is similar enough to a second gene CHM that it too needed full-on phylogenetic annotation -- it has no indel in any species so must not be cross-annotated for CHML in species without assemblies. The key to that is including upstream amino acids where sufficient divergence between the two genes resides.

The background story here is a common one in gene dosage compensation. In the amniote ancestor and birds and lizards today there is but one multi-exonic gene CHM. In mammals, as the sex chromosomes underwent upheaval, the ortholog ended up on chrX which has implications for reduced levels of expression compared to an autosomal gene. That may have favored persistence of a retroprocessed (intronless) copy on chr1. In marsupials, the two copies remained quite similar. In placentals, the second gene CHML diverged extensively from the first while remaining well conserved within its orthology class.

The one-residue indel appears cleanly restricted to Pegasoferae. There are 5 Laurasiatheres with it and 5 without it, which needs further buttressing by PCR (adding more basal species has the effect of localizing the event farther back on the stem). The parental gene did not develop the indel in any bioinformatically accessible species.

Interestingly, the retrogene CHML landed within intron 1 of encephalopsin OPN3 with the same direction of transcription. This raises some questions about how CHML is translated (as it would apparently be spliced out). Encephalopsin has an interesting history in mammals involving multiple independent losses.

The region annotated below corresponds to a known domain called GDI (for GDP dissociation inhibitor: pfam00996). The 3D structure of this region is available in the parent gene in rat, PDB 1LTX so the structural location of the indel could be determined. Very likely it lies within a loop and has minimal functional impact.

Analysis of a five residue deletion in DIO1

The five amino acid deletion here occurs in first exon of iodothyronine deiodinase, a much-studied gene. A consistent picture is seen in dog, bears, cat, horse, macrobat, and microbat with artiodactyls (cow, dolphin, pig, vicuna) and eulipotyphlya (hedgehog and shrew) lacking the deletion, which is evidently the ancestral condition judging by marsupials, more basal Atlantogenata, and Euarchontoglires.

This event supports -- but does not by itself establish -- the topology ((((dog horse) bat) cow) eulipotyphla) at the expensive of ((((dog horse) cow) bat) eulipotyphla). It does not speak to various possible internal resolutions of ((dog horse) bat). Longer indels are uncommon however so it is difficult to avoid the conclusion that artiodactyls are an outgroup (without invoking lineage-sorting).

Mammals have two other iodothyronine deiodinase paralogs but these are sufficiently diverged at this exon to prevent any annotational confusion. They too are full-length in this region, suggesting that length is a very ancient character indeed. No 3D structure is available for any member of the family but they can be supposed to have the basic ferredoxin fold (like many other selenoproteins).

Note two species within Afrothera have an 8 residue deletion in a similar region of the protein, suggesting it is a loop region inessential to protein function. No data is available for tenrec or other species in this clade, so it cannot be more precisely dated without PCR of additional species. However armadillo and sloth lack the deletion, bounding its timeframe somewhat.

The alignment below shows the deletion in 'difference' mode relative to human. Here dots mean the residue matches human. This mode of display results in less visual clutter while emphasizing degree of conservation, which is an important quality parameter for phylogeneticall informative indels.

Possibly informative whole gene duplication in bat opsin

An apparental functional duplication of a visual opsin gene has been reported previously in the megabat Haplonycteris fischeri that is missing in Pteropus and Myotis. This is another form of rare genomic event, a large insertion indel since most mammals have but two imaging opsins.

This gene duplication might simply be restricted to this one genus (or even this one species). Alternatively it might have greater phylogenetic depth and be somewhat informative in resolving intra-bat taxonomy. This would require PCR of many additional bat species since no further genomic work is anticipated any time soon. It is not relevent to Pegasoferae per se since bats are clearly monophyletic overall, even as the macro/micro distinction remains equivocal as a taxonomic character.

The key paragraph in the article:

"When we sequenced the region from exon 4 to exon 5 of the M/L opsin gene in an individual from H. fischeri, an additional copy was found. While exons 4 and 5 of the two copies were identical at nonsynonymous sites, the two copies of intron 4 differed by 20 nucleotides and 11 indels, including one large indel of ~750 bp and involving a total of 794 sites. These differences appeared to be too large to represent two alleles of the same locus, indicating the possibility of two duplicate genes. Indeed, the sequence data from intron 5 revealed three different sequences, denoted as 5–1, 5–2, and 5–3 (fig. 4). Whereas introns 5–1 and 5–2 may represent two polymorphic alleles from the same locus, intron 5–3 differs from intron 5–1 at 10 sites and should represent another locus. (Because a locus can have at most only two different sequences, the presence of three sequences should indicate a gene duplication.)"

Possibly informative indel in OPN4 bat melanopsin

Another potentially informative indel for bats -- a one residue deletion -- separates Myotis from everything else. Its phylogenetic depth can only be determined by sequencing additional species of bats. It might contribute to establishing microbates are polyphyletic (or it could simply be an idiosyncracy of the genus Myotis). The indel occurs in a well-understood region of melanopsin, the only rhabdomeric opsin that has persisted into mammals. This gene is not directly involved in imaging vision but the structural/functional implications of the indel still might be determinable.

Possibly informative indel in SS18L1 supporting chiroptera + artiodactyl

This autosomal indel, at face value, groups artiodactyls and bats to the exclusion of dog, horse, shrew, and hedgehog. Note the ambient gene SS18L1 has rather anomalous composition in its distal half and the exon containing the indel falls under standard masking filters such as seg. It is anomalous in the mammalian proteomewide context in glutamine and tyrosine, no doubt because the dna composition of the exon exhibits very high GC, 32A 18T 58C 57G. The exon has some self-similarity upon blast to a distal region of the gene:

SNPPSQQGSSQQYLGQEEYYGEQYSHSQGAAEPMGQQ
S+  S QG SQ Y GQ          SQG++  MGQ+
SHYSSAQGGSQHYQGQSSI-AMMGQGSQGSSM-MGQR

The alignment shows the indel phylo-consistently in 3/3 available artiodactyls and 2/2 available bats but not in 4/4 other Laurasiatheres or other vertebrates. The percent identity of human to artiodactyls fallsoff fairly dramatically relative to percent identity to horse and dog (or even marsupial and platypus). It's most unusual for a human/cow ortholog to be more diverged than human/lizard. Some Atlantogenata also appear to be diverging rapidly but without the indel. This cannot be attributed to misalignment or paralog/pseudogene confusion.

In summary, this indel demonstrates some of the subtle issues in using rare genomic events in phylogeny. The indel supports cow + bat topology but not so strongly given the compositional propensity to homoplasy in the context of rapid sequence divergence in some clades.

Possibly informative indel in ZNF622 supporting chiroptera + artiodactyl

This 3 residue deletion in exon 1 of ZNF622 seems informative but has some troubling side issues. First, two species seem to have a second somewhat diverged copy, rat and mouse lemur. With rat, it is on another chromosome but mouse has no counterpart. If this gene is prone to duplication, it becomes difficult in species without global assemblies (ie bats) to establish orthology.

Second, only dog is available for carnivores and its sequence is disturbingly diverged in percent identity -- 72% in a gene where cow is 82% with the 3 residue indel and 88% if the indel is filled by consensus sequence. The dog gene is in syntenic position with human. Meanwhile earlier diverged and usually fast evolving species like armadillo and rabbit are over 98% identical to human. Horse at 94% is about what is expected. Third, horse dna exhibits slight tandem repeat at both dna and protein level at the site of the indel that might be conducive to repeated replication slippage events.

This indel would benefit from PCR of additional carnivores, pangolin, perissodactyl, and bat species to expand representation of those divisions. It is necessary to develop an understanding on when and why the carnivore gene began to diverge anomalously. It is unusual to see 3 aa deletion in a gene that is fairly well conserved to depth but it may be no coincidence that laurasiatheres other than horse have both rapid divergence and the indel in some species.

Two residue insert in cow and bat CD5 illustrates homoplasy

Exon 5 of gene CD5 exhibts a two residue insertion in cow, sheep, and bat relative to other placental mammals. However, the insertion is not found in other artiodactyls (dolphin, pig, and vicugna) and so is homoplasic. Grouping bovids with microbats to the exclusion of other even-hoofed animals is a ridiculous concept.

Macrobat has no available data but this locus is unsuitable as a phylogenetic marker within bats. It is not so clear from dna alignement that the insertion occurs in quite the same spot in cows and microbat. This cell surface receptor CD5 is evolving too fast for all but the narrowest phylogenetic purposes -- the percent identity within Laurasiatheres is 70% relative to dog, far too low for an informative rare genomic event.

Deletion in SLC44A1 in bat and cow again homoplasic

This loss of one amino acid in the conserved transport gene SLC44A1 is limited to cow, sheep, and microbat. It is absent in dog, cat, horse, pig, vicugna, and macrobat. A moderately close paralog (at least in this exon) SLC44A3 is not an actual source of confusion; it has no indel in any species. This rare genomic event is not suited for within-bat or within-artiodactyl tree refinement because of this homoplasy, as well as an unrelated 3 aa loss in guinea pig.
