The proteomic response to temperature in the coccolithophore Emiliania huxleyi


ABSTRACT: The coccolithophore Emiliania huxleyi was acclimated to growth under three temperatures (17, 23 and 28°C), representing control, sub-optimal and supra-optimal warming respectively. Shotgun proteomic analysis was utilised to examine the molecular mechanisms driving the cellular response of E. huxleyi to warming. This revealed a significant reprogramming of the cellular proteome in-line with existing data relating to the relative sensitivities of phytoplankton photosynthesis and respiration to increasing temperature.

Marine phytoplankton contribute substantially to the global flux of carbon from the atmosphere to the deep ocean. Sea surface temperatures will inevitably increase in line with global climate change, altering the performance of marine phytoplankton. Differing sensitivities of photosynthesis and respiration to temperature, will likely shift the strength of the future oceanic carbon sink. To further clarify the molecular mechanisms driving these alterations in phytoplankton function, shotgun prote  ...[more]
