Coat protein of the Ectocarpus siliculosus virus.
Ectocarpus siliculosus virus, EsV, multiplies in sporangia and gametangia of the marine brown alga Ectocarpus siliculosus. We describe an improved method for the isolation of morphologically intact and infectious virus from diseased plants. We show that treatment of virus particles with high concentrations of CsCl results in a substantial loss of structural proteins. One of the proteins which r...
متن کاملCryopreservation of the model alga Ectocarpus (Phaeophyceae).
The brown alga Ectocarpus has recently become the first fully sequenced multicellular alga and is an important biological model. Due to the large and growing number of Ectocarpus strains isolated and maintained by the research community, including increasing numbers of mutants, there is an urgent need for developing reliable, cost-effective long-term maintenance techniques. We report here that ...
متن کاملMaullinia ectocarpii gen. et sp. nov. (Plasmodiophorea), an intracellular parasite in Ectocarpus siliculosus (Ectocarpales, Phaeophyceae) and other filamentous brown algae.
An obligate intracellular parasite infecting Ectocarpus spp. and other filamentous marine brown algae is described. The pathogen forms an unwalled multinucleate syncytium (plasmodium) within the host cell cytoplasm and causes hypertrophy. Cruciform nuclear divisions occur during early development. Mature plasmodia become transformed into single sporangia, filling the host cell completely, and t...
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 کاملApplication of Molecular Modelling Techniques to Pheromones of the Marine Brown Algae Cutleria multifida and Ectocarpus siliculosus (Phaeophyceae). Metalloproteins as Chemoreceptors?
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...
