Experimental Approaches and Protocols for Functional Genomics of Coccolithophorid Phytoplankton
Coccoiitliophores play a crucial role in the marine carbon cycle. The formation of Calcite (CaC03) by coccolithophores in surface waters and its subsequent removal by sinking has important implications for the flux of inorganic carbon into the oceans. To understand the impact of global change, such...
