Application of Molecular Modelling Techniques to Pheromones of the Marine Brown Algae Cutleria multifida and Ectocarpus siliculosus (Phaeophyceae). Metalloproteins as Chemoreceptors?
نویسنده
چکیده
The conformation o f the two algal pheromones ectocarpene (1) and multifidene (2) was studied by the active analogue approach using molecular mechanics calculations within the software package SYBYL. A common conformation for both pherom ones and all active analogues was filtered out by superpositionand energy minimizing procedures starting from crystallographic data of the Cambridge Structural Data Base (CSD). The interaction of the algal receptor systems with their olefinic pherom ones and heteroanalogues is in excellent agreement with the assumption of a receptor-bound metal cation acting as the binding side.

Taxonomic reappraisal of the freshwater brown algae Bodanella, Ectocarpus, Heribaudiella, and Pleurocladia (Phaeophyceae) on the basis of rbcL sequences and morphological characters
This study examines the phylogenetic relations among freshwater species of brown algae using RUBISCO large subunit (rbcL) sequences, in conjunction with diagnostic morphological and developmental traits. We focused on the phylogenetic and taxonomic placement of five freshwater species, Bodanella lauterborni, Ectocarpus siliculosus, Heribaudiella fluviatilis, Pleurocladia lacustris, and Porterin...
متن کاملLaser capture microdissection in Ectocarpus siliculosus: the pathway to cell-specific transcriptomics in brown algae
Laser capture microdissection (LCM) facilitates the isolation of individual cells from tissue sections, and when combined with RNA amplification techniques, it is an extremely powerful tool for examining genome-wide expression profiles in specific cell-types. LCM has been widely used to address various biological questions in both animal and plant systems, however, no attempt has been made so f...
متن کاملSurface-bound iron: a metal ion buffer in the marine brown alga Ectocarpus siliculosus?
Although the iron uptake and storage mechanisms of terrestrial/higher plants have been well studied, the corresponding systems in marine algae have received far less attention. Studies have shown that while some species of unicellular algae utilize unique mechanisms of iron uptake, many acquire iron through the same general mechanisms as higher plants. In contrast, the iron acquisition strategi...
متن کاملCopper-induced intra-specific oxidative damage and antioxidant responses in strains of the brown alga Ectocarpus siliculosus with different pollution histories.
Inter- and intra-specific variation in metal resistance has been observed in the ecologically and economically important marine brown macroalgae (Phaeophyceae), but the mechanisms of cellular tolerance are not well elucidated. To investigate inter-population responses of brown seaweeds to copper (Cu) pollution, the extent of oxidative damage and antioxidant responses were compared in three stra...
متن کاملETOILE regulates developmental patterning in the filamentous brown alga Ectocarpus siliculosus.
Brown algae are multicellular marine organisms evolutionarily distant from both metazoans and land plants. The molecular or cellular mechanisms that govern the developmental patterning in brown algae are poorly characterized. Here, we report the first morphogenetic mutant, étoile (etl), produced in the brown algal model Ectocarpus siliculosus. Genetic, cellular, and morphometric analyses showed...
