Abstract

Asymmetrical distribution of mRNA has been associated with polarization and cell fate determination during early development of animal embryos. In this report we determine the distribution pattern of poly(A)+ RNA during early embryogenesis of the brown alga Fucus. Poly(A)+ RNA is symmetrically distributed in the egg and early zygote. Shortly after the polar axis is established, poly(A)+ RNA becomes segregated to the thallus pole of the zygote. Following cytokinesis, most of poly(A)+ RNA is partitioned into the thallus cell. We show that the spatial redistribution of poly(A)+ RNA requires intact microfilaments and the fixation of the polar axis, but is not dependent upon polarized growth of the rhizoid, intact microtubules, or orientation of the division plane.
