Dynamic Regulation of Photoprotection Determines Thermal Tolerance of two Phylotypes of Symbiodinium Clade A at two Photon Fluence Rates. | Coral bleaching is the manifestation of the dysfunction of the symbiosis between scleractinian corals and dinoflagellates of the diverse genus Symbiodinium and is induced by elevated temperatures and high irradiance. We investigated the photophysiological response of two genetically distinct Symbiodinium subtypes within clade A upon exposure to elevated temperatures at two light intensities for three weeks. While both subtypes displayed a characteristic photoacclimation to high light (decrease i ... | 2011 | 22117932 |
