In non-classical model species, Next Generation Sequencing increases the ability to analyze the expression of transcripts/genes. In this study, paired-end Illumina HiSeq sequencing technology has been employed to describe a larval transcriptome generated from 64h post-fertilization pluteus larvae of the brittle star Amphiura filiformis. We focused our analysis on the detection of actors involved in...
Background In metazoans, opsins are photosensitive proteins involved in both vision and non-visual photoreception. Echinoderms have no well-defined eyes but several opsin genes were found in the purple sea urchin (Strongylocentrotus purpuratus) genome. Molecular data are lacking for other echinoderm classes although many species are known to be light sensitive. Results In this study focused on the...
Individuals of the cosmopolitan ophiuroid Amphipholis squamata were collected from eight stations. Eleven colour varieties were described and their distribution was non-random among stations. This suggests that the varieties differ in ecophysiologic tolerance and that their geographical distribution is modulated by environmental conditions. Varieties also differed in bioluminescence. Contrary to kinetics,...
