Molecular Analysis of Tube Cement of the Biofouling Tubeworm Hydroides elegans

Abstract

Hydroides elegans is a common fouler that secretes a tube and strong cement. Little is known about the composition of either of these structures or the genes encoding them. We determined the amino acid composition of them. The ratios of the amino acids in the tubes and cements are different from other marine cements. We used next-gen. sequencing and determined that no marine-invert. cement homologs were found in the transcriptomes of the shell gland. We then used whole-mount in situ hybridizations to determine where highly expressed transcripts are expressed in the worms. Initial results show these transcripts are uniquely expressed in and around the shell and may be components of the cement.
