REPTILIAN BRAIN TRANSCRIPTOMES

WARNING: THERE IS A VERSION 2.0 OF THE REPTILIAN-TRANSCRIPTOMES DATABASE AVAILABLE HERE

Why the Brain?

We chose to focus on the brain reptilian transcriptome because (i) the brain exhibits one of the most complex (i.e., diverse) transcriptomes of all organs in vertebrates; hence, it is a tissue of choice for sequencing a maximum number of transcripts while reducing the need for normalization; and (ii) reptilian species have been incorporated in comparative analyses of the vertebrate brain aimed at understanding the evolution of the sensory and cognitive novelties associated with the vertebrate central nervous system.

We present here the results obtained from sequencing the transcriptomes of four reptilian and one avian species:

1. 1.The Nile crocodile (Crocodylus niloticus),
   

2. 2.The oviparous Corn snake (Elaphe guttata),
   

3. 3.The Bearded dragon (Pogona vitticeps),
   

4. 4.The red-eared turtle (Trachemys scripta), and
   

5. 5.The chicken (Gallus gallus) as a reference species.
