Evolution of Two Genomes Impact of Sequence Divergence on Mitochondrial Function
Meeting Abstract 48.5 Saturday, Jan. 5 Evolution of Two Genomes: Impact of Sequence Divergence on Mitochondrial Function BARIS, T.Z.*; OLEKSIAK, M.F.; CRAWFORD, D.L.; University of Miami/Rosenstiel School of Marine and Atmospheric Science tbaris@rsmas.miami.edu We are investigating the divergence in oxidative phosphorylation (OxPhos) metabolism among populations of Fundulus heteroclitus. The OxPhos pathway occurs in mitochondria and uses oxygen […]
The response of octopus chromatophores to light is independent of the CNS and may be mediated by r-opsin phototransduction genes
Meeting Abstract 48.2 Sunday, Jan. 5 10:15 The response of octopus chromatophores to light is independent of the CNS and may be mediated by r-opsin phototransduction genes RAMIREZ, D*; OAKLEY, TH; Univ. of California, Santa Barbara ramirez@lifesci.ucsb.edu Both eyed and eyeless animals depend on sensors in their skin to detect changes in light, a phenomenon known as […]
