(ProTECTOR) in the Bay Islands of Honduras. The report covers activities of ProTECTOR up to and including the 2008 calendar year and is provided in partial fulfillment of the permit agreement provided to ProTECTOR from 2006 to the end of 2008 by the Secretariat for Agriculture and Ranching (SAG). ACKNOWLEDGEMENTS ProTECTOR and TAPS recognize that without the financial and logistical assistance of the “Escuela de Buceo Reef House,” this project would not have been initiated. We thank the owners and staff of that facility for their interest in sea turtle conservation and their invaluable efforts on behalf of the sea turtles of Honduras. -

Their purification from crude extracts was mainly performed by using affinity chromatography and gel filtration techniques. Other protocols were also developed in order to collect and study sponge lectins, including screening of sponge genomes and expression in heterologous bacterial systems. -

Horizontal Gene Transfer in the Sponge Amphimedon Queenslandica
Horizontal gene transfer in the sponge Amphimedon queenslandica Simone Summer Higgie BEnvSc (Honours) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 School of Biological Sciences Abstract Horizontal gene transfer (HGT) is the nonsexual transfer of genetic sequence across species boundaries. Historically, HGT has been assumed largely irrelevant to animal evolution, though widely recognised as an important evolutionary force in bacteria. From the recent boom in whole genome sequencing, many cases have emerged strongly supporting the occurrence of HGT in a wide range of animals. However, the extent, nature and mechanisms of HGT in animals remain poorly understood. Here, I explore these uncertainties using 576 HGTs previously reported in the genome of the demosponge Amphimedon queenslandica. The HGTs derive from bacterial, plant and fungal sources, contain a broad range of domain types, and many are differentially expressed throughout development. Some domains are highly enriched; phylogenetic analyses of the two largest groups, the Aspzincin_M35 and the PNP_UDP_1 domain groups, suggest that each results from one or few transfer events followed by post-transfer duplication. Their differential expression through development, and the conservation of domains and duplicates, together suggest that many of the HGT-derived genes are functioning in A. queenslandica. The largest group consists of aspzincins, a metallopeptidase found in bacteria and fungi, but not typically in animals. I detected aspzincins in representatives of all four of the sponge classes, suggesting that the original sponge aspzincin was transferred after sponges diverged from their last common ancestor with the Eumetazoa, but before the contemporary sponge classes emerged. -

Here we present the first sponge agent belonging to the group of ASABF-type antimicrobial peptides. The ASABF gene was identified and cloned from the demosponge Suberites domuncula. -
