Abstract
This work will investigate ion channel regulation in localised regions of Fucus zygotes and their modulation by external signals, particularly light. Patch clamp studies will concentrate initially on apical and sub-apical plasma membrane of rhizoid cells, involving detailed characterization of Ca2+-. K+- and C1- conducting channels, already identified in the rhizoid apex. Their regulation by Ca2+, light, pH, voltage, calmodulin and other messengers will be studied in depth using whole cell, cell attached and excised patch methods and laser microsurgery. High resolution studies of cytoplasmic CA2+ will locate and Ca2+ microdomains in response to unilateral illumination. Ion channels in the vacuole and nucleus will also be explored.
