The analysis of eight transcriptomes from all poriferan classes reveals surprising genetic complexity in sponges.
Sponges (Porifera) are among the earliest evolving metazoans. Their filter-feeding body plan based on choanocyte chambers organized into a complex aquiferous system is so unique among metazoans thatExpand

Comparative description of ten transcriptomes of newly sequenced invertebrates and efficiency estimation of genomic sampling in non-model taxa
IntroductionTraditionally, genomic or transcriptomic data have been restricted to a few model or emerging model organisms, and to a handful of species of medical and/or environmental importance.Expand

Revisiting metazoan phylogeny with genomic sampling of all phyla
Proper biological interpretation of a phylogeny can sometimes hinge on the placement of key taxa—or fail when such key taxa are not sampled. In this light, we here present the first attempt toExpand

Optimization of preservation and storage time of sponge tissues to obtain quality mRNA for next‐generation sequencing
Transcriptome sequencing with next‐generation sequencing technologies has the potential for addressing many long‐standing questions about the biology of sponges. Transcriptome sequence qualityExpand

Reproduction in a carnivorous sponge: the significance of the absence of an aquiferous system to the sponge body plan
SUMMARY Sponges usually produce, release, and capture gametes via the aquiferous system, and so the absence of both choanocytes and an aquiferous system in the carnivorous sponge AsbestoplumaExpand

Sterol and genomic analyses validate the sponge biomarker hypothesis
Significance An unusual molecule is found in rocks ∼650–540 million y old, and its likely precursor, 24-isopropylcholesterol (24-ipc), is produced by some modern sea sponges. The sterane hydrocarbonExpand

At the point in animal evolution when cells began to adhere to each other they presumably initially functioned as colonies. The formation of an epithelium that enclosed and controlled an internalExpand

Transcriptomic analysis of differential host gene expression upon uptake of symbionts: a case study with Symbiodinium and the major bioeroding sponge Cliona varians
BackgroundWe have a limited understanding of genomic interactions that occur among partners for many symbioses. One of the most important symbioses in tropical reef habitats involves Symbiodinium.Expand

Support for a clade of Placozoa and Cnidaria in genes with minimal compositional bias
The phylogenetic placement of the morphologically simple placozoans is crucial to understanding the evolution of complex animal traits. Here, we examine the influence of adding new genomes fromExpand

Inferring the ancestral sexuality and reproductive condition in sponges (Porifera)
Considerable diversity abounds among sponges with respect to reproductive and developmental biology. Their ancestral sexual mode (gonochorism vs. hermaphroditism) and reproductive conditionExpand
