Research Abstract |
To understand the process and origin of various eyes, I conducted comparative evolutionary study by using next generation sequence technology. For the purpose, I took two different types of Jellyfish with and without eye and also dinoflagellate with different types of lens eye. RNA-seq by next generation sequence technology performed collection of gene expression profiles of the species. The visual pigment of dinoflagellate showed the similarity with bacterial pigment and it suggests the origin of their eye-like structure related to bacterial origin. The other side, the result of jellyfish showed the molecules related their lens development evolutionaliry related with our genes, thus, jellyfish already gain molecular system for lens conformation before establishing nervous system. Now, we still continue more fine analysis of the data.
