Abstract:

Sensitivity to ultraviolet (UV) radiation (UV-A, λ = 315-400 nm; plus UV-B, λ = 280-315 nm) of zygotes of the brown alga Fucus serratus L. (Phaeophyta) has been assessed through effects on growth of developing germlings. Different stages of development were distinguished by considering 5 h periods of time after fertilisation. Both the stage of the zygote and the UV radiation condition significantly affected growth of developing germlings. The negative response of growth rate of early stages of the zygotes to UV radiation seemed to be caused by UV-B rather than UV-A radiation, as the lowest rel

Abstract:

Reciprocal crosses between male and female gametes of Ascophyllum nodosum (L.) LeJolis and Fucus vesiculosus L. were made from plants collected at Tor Bay, Nova Scotia. Crosses within each species were viable and resulted in normal zygote development. Hybrids occurred in low frequency in the cultures (ca. 1–5%) and developed either an initial rhizoid or underwent one or two internal divisions. Hybrid zygotes did not develop further. More developing embryos were observed in crosses when F. vesiculosus provided the eggs, and these zygotes developed longer rhizoids. Maximum development was to thr

Abstract:

The settlement of spores and larvae on hard substrates has been shown to be influenced by many factors, but few studies have evaluated how underlying bedrock may influence recruitment. The characteristics of coastal rock types such as color, heat capacity, mineral size, and free energy have all been implicated in settlement success. We examined the influence of naturally occurring rock types on the initial attachment of zygotes of the brown alga Fucus spiralis Linnaeus 1753. We also assessed the dislodgment of zygotes on four bedrock types after initial attachment in laboratory experiments usi

Abstract:

In this study, we investigate the role of polar secretion and the resulting asymmetry in the cell wall in establishing polarity in Fucus zygotes. We have utilized brefeldin-A to selectively interrupt secretion of Golgi-derived material into the cell wall as assayed by toluidine blue O staining of sulfated fucoidin. We show that the polar secretion of Golgi-derived material is targeted to a cortical site of the zygote identified by the localization of actin filaments and dihydropyridine receptors. The deposition of Golgi-derived material into the cell wall at this target site is temporally coin

Abstract:

SummaryIn the marine brown alga,Fucus, two poles are differentiated before cell division determining the future rhizoid or thallus. We have used a combination of the Ca2+-sensitive dye Calcium Green and the pH-sensitive dye SNARF monitored at pH-insensitive wavelengths to obtain confocal ratio images of free cytoplasmic calcium distribution at different stages in polarisingFucuszygotes. These dyes have the advantage that they can be used in most confocal microscopes and their longer excitation wavelengths greatly reduce autofluorescence problems.

Abstract:

The early embryo of the brown alga Fucus comprises two cell types, i. e. rhizoid and thallus which are morphogically and cytologically distinguishable. Previous work has pointed to the cell wall as a source of position-dependent information required for polarisation and fate determination in the zygote and 2-celled embryo. In this study we have analysed the mechanism(s) of cell fate control and pattern formation at later embryonic stages using a combination of laser microsurgery and microinjection. The results indicate that the cell wall is required for maintenance of pre-existing polarity in

Abstract:

Zygotes of the Fucales (Phaeophyceae) have been widely used as a model system to study plant cell polarity. Zygotes in the early stages of development are apolar. During the first cell cycle, a gradual cytoplasmic re-organisation, oriented by numerous environmental stimuli, replaces the initial spherical symmetry by a highly polarised morphology. Gradients of cytoplasmic free Ca<SUP>2+</SUP> and of the Ca<SUP>2+</SUP> binding protein, calmodulin, have been observed in the growing tips of polarised plant cells such as root hairs and pollen tubes. Moreover, calmodulin is essential for budding in
