Cytoplasmic calcium gradients and calmodulin in the early development of the fucoid alga Pelvetia compressa.


The predicted existence of cytoplasmic Ca2+ gradients during the photopolarization of the zygotes of the brown algae, Pelvetia and Fucus, has proved to be difficult to establish, and the downstream targets of the putative gradients are not known. We have used quantitative microinjection of the long excitation wavelength Ca2+ indicator, Calcium Crimson, and… (More)
