Glutathione (GSH) Production as Protective Adaptation Against Light Regime Radiation of Symbiodinium Natural Population
Abstract: Glutathione (GSH),
as a wide range of low molecular weight, which found in marine microalgae and
event bacteria, are essential to prevent photooxidation and productivity loss
from these Radical Oxigen Species (ROS). Symbiodinium, endo-symbiont of corals,
were exposed with different UV radiation combined with irradiance treatments to
explore biomass specific initial response. Intracellular glutahione was
observed as potential adaptive response of Symbiodinium population under
environmental specific stress. The result showed that GSH production increased
significantly with increasing irradiance and/or UV levels. GSH concentration
was fluctuated among populations exposed by different irradiance treatments,
but not effected by UV and irradiance exposure. GSH production as a response of
UV exposure was higher than irradiance treatments. Both these high correlative
fluctuation of intracellular GSH production and the presence of both treatments
indicated protective specific adaptation of Symbiodinium under specific
environmental stress, respectively.
