Previous work has shown that distinct Ca2+ gradients precede and predict the loci of germination of the zygotes of the brown alga, Silvetia compressa (J. Agardh) E. Serrão, T.O. Cho, S.M. Boo et Brawley, that are polarized by unilateral blue light. We show here that dark-grown S. compressa zygotes also form cytosolic Ca2+ gradients prior to germination and then germinate from the site of elevated Ca2+. In no case did germination occur without a prior formation of a Ca2+ gradient. Using the self… CONTINUE READING
