Response to Pisani et al.

Tracing the origins of dim-light vision in vertebrate evolution has important palaeobiological and molecular implications for the evolution of vision. The last common ancestor of the vertebrates is thought to have possessed a conebased (photopic) visual system that operated in brightly-lit shallow marine water [1,2]. This assumption is mainly based on the phylogeny of the visual pigment (opsin)...

A Cambrian origin for vertebrate rods

Vertebrates acquired dim-light vision when an ancestral cone evolved into the rod photoreceptor at an unknown stage preceding the last common ancestor of extant jawed vertebrates (~420 million years ago Ma). The jawless lampreys provide a unique opportunity to constrain the timing of this advance, as their line diverged ~505 Ma and later displayed high-morphological stability. We recorded with ...

Invasion of Ancestral Mammals into Dim-light Environments Inferred from Adaptive Evolution of the Phototransduction Genes

Nocturnality is a key evolutionary innovation of mammals that enables mammals to occupy relatively empty nocturnal niches. Invasion of ancestral mammals into nocturnality has long been inferred from the phylogenetic relationships of crown Mammalia, which is primarily nocturnal, and crown Reptilia, which is primarily diurnal, although molecular evidence for this is lacking. Here we used phylogen...

Phylogenetic Analysis of Three Long Non-coding RNA Genes: AK082072, AK043754 and AK082467

Now, it is clear that protein is just one of the most functional products produced by the eukaryotic genome. Indeed, a major part of the human genome is transcribed to non-coding sequences than to the coding sequence of the protein. In this study, we selected three long non-coding RNAs namely AK082072, AK043754 and AK082467 which show brain expression and local region conservation among vertebr...

Ciliary photoreceptors with a vertebrate-type opsin in an invertebrate brain.

For vision, insect and vertebrate eyes use rhabdomeric and ciliary photoreceptor cells, respectively. These cells show distinct architecture and transduce the light signal by different phototransductory cascades. In the marine rag-worm Platynereis, we find both cell types: rhabdomeric photoreceptor cells in the eyes and ciliary photoreceptor cells in the brain. The latter use a photopigment clo...

Vertebrate rhodopsin adaptation to dim light via rapid meta-II intermediate formation.

Rhodopsin is a photoreceptive protein present in vertebrate rod photoreceptor cells, which are responsible for scotopic vision. Recent molecular studies have shown that several aquatic vertebrate species have independently acquired rhodopsin containing Asp83Asn, Glu122Gln, and Ala292Ser substitutions, causing a blue shift in the rhodopsin absorption spectra for adaptation to the blue-green phot...
