Frequent Clonality in Fucoids (fucus Radicans and Fucus Vesiculosus; Fucales, Phaeophyceae) in the Baltic Sea(1).
Asexual reproduction by cloning may affect the genetic structure of populations, their potential to evolve, and, among foundation species, contributions to ecosystem functions. Macroalgae of the genus Fucus are known to produce attached plants only by sexual recruitment. Recently, however, clones of attached plants recruited by asexual reproduction were observed in a few populations of Fucus ra...
متن کاملSeasonal Variations in Surface Metabolite Composition of Fucus vesiculosus and Fucus serratus from the Baltic Sea
Perennial macroalgae within the genus Fucus are known to exude metabolites through their outer thallus surface. Some of these metabolites have pro- and/or antifouling properties. Seasonal fluctuations of natural fouling pressure and chemical fouling control strength against micro- and macrofoulers have previously been observed in Fucus, suggesting that control strength varies with threat. To da...
متن کاملWave Propagation in Fucus Rhizoid Cells
Both Ca 2 and reactive oxygen species (ROS) play critical signaling roles in plant responses to biotic and abiotic stress. However, the positioning of Ca 2 and ROS (in particular H 2 O 2 ) after a stress stimulus and their subcellular interactions are poorly understood. Moreover, although information can be encoded in different patterns of cellular Ca 2 signals, little is known about the subcel...
متن کاملActin Localization during Fucus Embryogenesis.
Embryogenesis in the Fucales serves as a model system for studying the acquisition of cellular and developmental polarity. Fertilized eggs bear no asymmetry, yet within 16 hours, a developmental axis is formed and the unicellular zygote germinates in accordance with this axis. Microfilaments (actin) play a crucial role in establishing the axis as evidenced by the inhibitory effects of cytochala...
متن کاملMitosis sans Mitosis: The Mitotic Oscillator in Differentiation.
Differentiation and proliferation are usually considered to be antagonistic partners in development. However, in a recent issue of Science, Al Jord et al. (2017) show that key regulators of the mitotic cycle are redeployed in differentiating multiciliated cells to promote ciliogenesis without mitotic progression.
