Exonic remnants of whole-genome duplication reveal cis-regulatory function of coding exons
Dong, Xianjun; Navratilova, Pavla; Fredman, David; Drivenes, Øyvind; Becker, Thomas S.; Lenhard, Boris (Journal article; Peer reviewed, 2009-12-06)Using a comparative genomics approach to reconstruct the fate of genomic regulatory blocks (GRBs) and identify exonic remnants that have survived the disappearance of their host genes after whole-genome duplication (WGD) ... -
The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus)
Eilertsen, Mariann; Drivenes, Øyvind; Edvardsen, Rolf; Bradley, Clarissa A.; Ebbesson, Lars O.E.; Helvik, Jon Vidar (Journal article; Peer reviewed, 2014)The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ... -
Genomic regulatory blocks underlie extensive microsynteny conservation in insects
Engström, Pär G.; Sui, Shannan J. Ho; Drivenes, Øyvind; Becker, Thomas S.; Lenhard, Boris (Journal article, 2007-11-07)Insect genomes contain larger blocks of conserved gene order (microsynteny) than would be expected under a random breakage model of chromosome evolution. We present evidence that microsynteny has been retained to keep large ... -
Molecular evidence that only two opsin subfamilies, the blue light- (SWS2) and green light-sensitive (RH2), drive color vision in Atlantic cod (Gadus morhua)
Valen, Ragnhild; Edvardsen, Rolf; Søviknes, Anne Mette; Drivenes, Øyvind; Helvik, Jon Vidar (Peer reviewed; Journal article, 2014-12-31)Teleosts show a great variety in visual opsin complement, due to both gene duplication and gene loss. The repertoire ranges from one subfamily of visual opsins (scotopic vision) including rod opsin only retinas seen in ... -
Transient photoreception in the hindbrain is permissive to the life history transition of hatching in Atlantic halibut
Eilertsen, Mariann; Valen, Ragnhild; Drivenes, Øyvind; Ebbesson, Lars O.E.; Helvik, Jon Vidar (Journal article; Peer reviewed, 2018)In nonmammalian vertebrates, photoreception takes place in the deep brain already early in development, but knowledge is lacking about the functions of these nonvisual photoreceptive systems. Prior to hatching, Atlantic ...
