Abstract

Calcifying marine coccolithophorid microalgae maintain exceptionally large sustained net trans-cellular Ca2+ fluxes from the external medium to the intracellular calcifying Golgi-derived compartment. How this is achieved while maintaining cytoplasmic Ca2+ homeostasis is presently unknown. These cells provide a unique model for the study of both calcium homeostasis and microscale biomineralisation. The proposed research will characterise the Ca2+ influx pathways at the plasma membrane and the responses of cytosolic Ca2+ to imposed Ca2+ influx plus determine the role of the capacitiative Ca2+ entry and the endoplasmic reticulum in trans-cellular Ca2+ transport by using a combination of electrophysiological, confocal imaging, microanalysis and biochemical approaches.
