Background: Ectocarpus siliculosus virus-1 (EsV-1) is a lysogenic dsDNA virus belonging to the super family of nucleocytoplasmic large DNA viruses (NCLDV) that infect Ectocarpus siliculosus, a marine filamentous brown alga. Previous studies indicated that the viral genome is integrated into the host by: 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.

A proteomic analysis combining peptide de novo sequencing and BLAST analysis was used to identify novel proteins involved in copper tolerance in the marine alga Scytosiphon gracilis (Phaeophyceae). Algal material was cultivated in seawater without copper (control) or supplemented with μg L -1 for 4 days, and protein extracts were separated Cited by:

Abstract. Copper-tolerant strains of the marine fouling alga Ectocarpus siliculosus (Dillw) Lyngb. have been recorded. The mechanisms of tolerance which may operate in a copper-tolerant strain were investigated by comparing the growth characteristics, copper content and extracellular organic production of tolerant and non-tolerant by: Tolerance to heavy metals has been reported for a large number of organisms; for example the marine fouling alga Ectocarpus siliculosus (Dillw.)

Occurrence of Ectocarpus: Ectocarpus is word-wide in distribution particulary in colder seas and Polar Regions.

Ectocarpus is very common on sea shore of Atlantic Ocean. Ectocarpus is found attached on sea rocks. Some species of Ectocarpus are epiphytic e.g., E. coniferus, and E. breviarticulatus grow on larger algae like Fucus and Laminaria.

BACKGROUND. Ectocarpus siliculosus is a small filamentous brown alga. Seaweeds of the genus Ectocarpus are found worldwide along temperate coastlines, where they grow on rocky substrates or epiphytically on other algae and seagrass.

Research on E. siliculosus has a long history (Charrier et al. ), and this was one of the reasons that led to this species being selected ∼7 yr ago as a.

The unilocular reproductive stages of the brown algaEctocarpus have been examined with the electron microscope. One observation in particular, which is believed to have been made for the first time in Phaeophycean studies, is that the zoospore derived from unilocular sporangia possesses a microanatomy considerably different from that of spores formed by plurilocular by:   Brown algae are sessile macro-organisms of great ecological relevance in coastal ecosystems.

They evolved independently from land plants and other multicellular lineages, and therefore hold several original ontogenic and metabolic features. Most brown algae grow along the coastal zone where they face frequent environmental changes, including exposure to toxic levels of heavy metals Cited by: 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.
