Nucleotide sequences in Procambarus clarkii

Crayfish is a model for studying the effect of light on locomotor activity and neuroendocrine functions. In this study, we have described 62 transcripts from the pleonal nerve cord of the crayfish, using bioinformatics tools that identify phylogenetic families of genes related to the light interaction in the extraretinal photoreceptors. We deposited all sequencing data in the GenBank database. Here shows supplemental data from the freshwater crayfish Procambarus clarkii. The results suggest that the genes related to ocular and extraocular light perception in the crayfish P. clarkii use common biosynthesis pathways and phototransduction cascades.
