E-MTAB-2430 - sponge body plan
Released on 1 May 2014, last updated on 24 October 2014
In order to compare sponge and eumetazoan (higher animal) body plans, we identified and studied expression of a broad range of eumetazoan developmental regulatory genes in Sycon ciliatum (Calcispongiae). In this species, embryonic development is semi-synchronous within a population, synchronous within individuals, and oocytes and embryos occupy a significant fraction of the volume of the sponges during the reproductive period. RNASeq libraries representing non-reproductive (somatic) tissue slices along the body axis, as well as oocytes, embryos and free swimming larvae were generated from material obtained by sampling throughout the life cycle.
RNA-seq of coding RNA, all pairs, co-expression, development or differentiation design
Calcisponges have a ParaHox gene and dynamic expression of dispersed NK homeobox genes. Sofia A. V. Fortunato, Marcin Adamski, Olivia Mendivil Ramos, Sven Leininger, Jing Liu, David E. K. Ferrier. Nature 514:620-623 (2014)
