These ancient animals inherited components of the first multicellular skeletogenic toolkit from the last common ancestor of the Metazoa. Using a paleogenomics approach, including gene- and protein-expression techniques and phylogenetic reconstruction, we show that a molecular component of this toolkit was the precursor to the alpha-carbonic anhydrases (alpha-CAs), a gene family used by extant animals in a variety of fundamental physiological processes. We used the coralline demosponge Astrosclera willeyana, a \"living fossil\" that has survived from the Mesozoic, to provide insight into the evolution of the ability to biocalcify, and show that the alpha-CA family expanded from a single ancestral gene through several independent gene- duplication events in sponges and eumetazoans."],["dc.identifier.doi","10.1126/science.1141560"],["dc.identifier.isi","000247602700038"],["dc.identifier.pmid","17540861"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/51136"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0036-8075"],["dc.title","Sponge paleogenomics reveals an ancient role for carbonic anhydrase in skeletogenesis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

This largely stems from the fact that techniques used to investigate a given (bio)mineral should ideally be married with techniques that provide insight into the biological mechanisms that form that mineral (and vice versa). We observe two broad challenges that inhibit a fluent exchange of ideas and information between mineralogists/materials scientists and biologists. First, the smorgasbord of emerging and rapidly evolving techniques available to mineralogists and biologists alike make it difficult not only for an expert to remain contemporary, but can be bewildering to the non-expert. Second, to truly integrate and relate a specific biological insight into the genesis of a biomineral, with the effect that insight has on the properties of the mineral itself, is not trivial. We propose that an evolutionary developmental biology (evo-devo) approach can not only address this challenge, it can also provide deep insight into how the rich diversity of metazoan mineralised structures evolved. While an evo-devo approach to biomineralogy has previously been employed by some groups, recent exciting methodological developments available to the molecular biologist now make this strategy even more attractive. In this short review we aim to outline our perception of the role that evo-devo can play within the field of biomineralogy, taking as a case study the past achievements, recent insights and some future research directions associated with gastropod shell formation.

Here we present the draft genome sequence of Amphimedon queenslandica, a demosponge from the Great Barrier Reef, and show that it is remarkably similar to other animal genomes in content, structure and organization. Comparative analysis enabled by the sequencing of the sponge genome reveals genomic events linked to the origin and early evolution of animals, including the appearance, expansion and diversification of pan-metazoan transcription factor, signalling pathway and structural genes. This diverse 'toolkit' of genes correlates with critical aspects of all metazoan body plans, and comprises cell cycle control and growth, development, somatic- and germ-cell specification, cell adhesion, innate immunity and allorecognition.

To explore the molecular mechanisms of this critical process in a nonmodel organism, the abalone Haliotis asinina, we employed cDNA microarrays. By comparing gene expression profiles through mid- to late larval development and metamorphosis, we identified 144 genes as candidates for a role in competence and/or metamorphosis. Gene characterization indicates similar to 60% of these are significantly similar to known genes from other taxa, while similar to 40% are novel. A high 49.3% of genes are gastropod or abalone specific, but none appears to be Lophotrochozoan specific, even though metamorphosis is thought to have had a separate origin in this group. Differentially expressed larval and postlarval genes can be clustered into five categories that reveal strikingly different temporal transcriptional patterns occurring during this phase of development. Some gene activation is contingent upon exogenous cues and correlates with initiation of settlement. Importantly, there is also extensive gene activity associated with the endogenous attainment of competence, which occurs before, and independent of, the exogenous induction of settlement. Our results show that as the haliotid veliger larva matures, it requires coordinated regulation of temporally different batteries of genes involved in a wide range of physiological and developmental processes associated with benthic colonization. Although the signalling pathways operating at metamorphosis may be conserved across the animal kingdom, it appears they regulate the expression of novel genes specific to abalone, gastropods and molluscs during H. asinina metamorphosis."],["dc.description.sponsorship","Australian Research Council"],["dc.identifier.doi","10.1111/j.1365-294X.2008.04078.x"],["dc.identifier.isi","263521800020"],["dc.identifier.pmid","19207244"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/17323"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell Publishing, Inc"],["dc.relation.issn","0962-1083"],["dc.title","Widespread transcriptional changes pre-empt the critical pelagic-benthic transition in the vetigastropod Haliotis asinina"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The appearance of disparate molluscan forms during this period leaves open the possibility that shells evolved independently and in parallel in at least some groups. To test this proposition and gain insight into the evolution of structural genes that contribute to shell fabrication, we compared genes expressed in nacre (mother-of-pearl) forming cells in the mantle of the bivalve Pinctada maxima and the gastropod Haliotis asinina. Despite both species having highly lustrous nacre, we find extensive differences in these expressed gene sets. Following the removal of housekeeping genes, less than 10% of all gene clusters are shared between these molluscs, with some being conserved biomineralization genes that are also found in deuterostomes. These differences extend to secreted proteins that may localize to the organic shell matrix, with less than 15% of this secretome being shared. Despite these differences, H. asinina and P. maxima both secrete proteins with repetitive low-complexity domains (RLCDs). Pinctada maxima RLCD proteins-for example, the shematrins-are predominated by silk/fibroin-like domains, which are absent from the H. asinina data set. Comparisons of shematrin genes across three species of Pinctada indicate that this gene family has undergone extensive divergent evolution within pearl oysters. We also detect fundamental bivalve-gastropod differences in extracellular matrix proteins involved in mollusc-shell formation. Pinctada maxima expresses a chitin synthase at high levels and several chitin deacetylation genes, whereas only one protein involved in chitin interactions is present in the H. asinina data set, suggesting that the organic matrix on which calcification proceeds differs fundamentally between these species. Large-scale differences in genes expressed in nacre-forming cells of Pinctada and Haliotis are compatible with the hypothesis that gastropod and bivalve nacre is the result of convergent evolution. The expression of novel biomineralizing RLCD proteins in each of these two molluscs and, interestingly, sea urchins suggests that the evolution of such structural proteins has occurred independently multiple times in the Metazoa."],["dc.identifier.doi","10.1093/molbev/msp278"],["dc.identifier.isi","000274786900010"],["dc.identifier.pmid","19915030"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/20476"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Oxford Univ Press"],["dc.relation.issn","0737-4038"],["dc.title","Parallel Evolution of Nacre Building Gene Sets in Molluscs"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
