Project description:Poriferans, like the demosponge Amphimedon queenslandica, are the earliest diverging metazoans and may hold the key to understanding the evolution of metazoan pathways. A. queenslandica exhibits a biphasic lifecycle, with free-swimming larvae and sessile adult stages. To study changes in the transcriptome during this period of morphological and ecological transition, we generated poly(A) fragment libraries for A. queenslandica at four developmental stages: precompetent and competent larvae, postlarvae, and adult. These libraries were sequenced using Applied Biosystems SOLiD technology. This study provides the most comprehensive analysis to date of gene expression in the sponge. It has elucidated the genes that define the two main phases of the sponge lifestyle and identified genes that are important for competence and metamorphosis. More importantly, this study has provided insights into the expression of the genes that characterize metazoan features, such as cell adhesion and differentiation, in an early metazoan.

Project description:Classical embryological studies revealed that during mid-embryogenesis vertebrates show similar morphologies. This “phylotypic stage” has recently received support from transcriptome analyses, which have also detected similar stages in nematodes and arthropods. A conserved stage in these three phyla has led us to ask if all animals pass through a universal definitive stage as a consequence of ancestral constraints on animal development. Previous work has suggested that HOX genes may comprise such a ‘zootypic’ stage, however this hypothetical stage has hitherto resisted systematic analysis. We have examined the embryonic development of ten different animals each of a fundamentally different phylum, including a segmented worm, a flatworm, a roundworm, a water bear, a fruitfly, a sea urchin, a zebrafish, a sea anemone, a sponge, and a comb jelly. For each species, we collected the embryonic transcriptomes at ~100 different developmental stages and analyzed their gene expression profiles. We found dynamic gene expression across all of the species that is structured in a stage like manner. Strikingly, we found that animal embryology contains two dominant modules of zygotic expression in terms of their protein domain composition: one involving proliferation, and a second involving differentiation. The switch between these two modules involves induction of the zootype; which in addition to homeobox containing genes, also involves Wnt and Notch signaling as well as forkhead domain transcription factors. Our results provide a systematic characterization of animal universality and identify the points of embryological constraints and flexibility.

Project description:The Crown-of-Thorns starfish (COTS), Acanthaster planci, is a highly fecund predator of reef-building corals distributed throughout the Indo-Pacific. COTS population outbreaks cause substantial loss of coral cover, diminishing the integrity and resilience of the reef ecosystems thus increasing their susceptibility to climate change. We sequenced genomes of A. planci from the Great Barrier Reef, Australia (GBR) and Okinawa, Japan (OKI) to guide identification of species-specific peptide communication with potential applications in mitigation strategies. The genome-encoded proteins excreted and secreted into the surrounding seawater by COTS forming aggregations and by those escaping the predatory giant triton snail, Charonia tritonis, were identified LC-MS/MS.
