Generation and expression of cell polarity in brown algal zygotes of the Fucales involve regulation of the actin cytoskeleton and localized secretion. We used degenerate PCR to isolate cDNAs that encode two small GTPases, FdRac1 and FdRab8, from zygotes of Fucus distichus (L.) Powell. Sequence analysis placed FdRac1 in the Rho family, which regulates actin, and FdRab8 in the Rab family, which regulates vesicle transport. As expected, bacterially expressed forms of both proteins bound GTP in… CONTINUE READING
