Description: |
Ectocarpus siliculosus is a filamentous brown alga (Heterokontophyta). Its genome was the first brown macroalgal genome to be sequenced, with the expectation that E. siliculosus will serve as a genetic and genomic model for brown macroalgae.The alga is unbranched and filamentous; it forms soft beards on larger plants or other firm substrata and grows up to 2 feet long. Plants tufted, often only one to a few cm tall, but in exceptional cases up to 20 cm. Axes freely branched, main axis not distingushable. Filaments up to 30μm in diameter, tapering toward the apices. Sometimes forming terminal pseudohairs. Original publication: Lyngbye, H.C. (1819). Tentamen hydrophytologiae danicae continens omnia hydrophyta cryptogama Daniae, Holsatiae, Faeroae, Islandiae, Groenlandiae hucusque cognita, systematice disposita, descripta et iconibus illustrata, adjectis simul speciebus norvegicis. pp. [i]-xxxii, [1]-248, 70 pls.
