. Among possible model organisms in the brown algae, ''Ectocarpus'' was selected for the relatively small size of its mature thallus and the speed with which it completes its life cycle. Tools available for ''Ectocarpus'' as a model species include a high quality genome sequence and both forward and reverse genetic methodologies, the latter based on CRISPR-Cas9.


Taxonomy and Nomenclature

Brown algae are heterokonts, a group that also includes diatoms and oomycetes. Despite their simple filamentous thalli, the Ectocarpales are part of the crown group of brown algal orders and are a sister group to the order Laminariales (kelps). The
type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ...
for the genus is '' Ectocarpus siliculosus'' ( Dillwyn) Lyngbye. In 1809, Dillwyn described ''Ectocarpus'' as ''Conferva siliculosa'' based on specimens collected by W.J. Hooker from Norfolk and East Sussex. In 1819, Lyngbye subsequently described ''Ectocarpus'' using a specimen from Denmark, citing ''C. siliculosa'' Dilwyn as its basionym.


Morphology

Studies on morphology have been limited for ''Ectocarpus'' as only two species in the genera (''E. siliculosus'' and ''E. fasciculatus)'' are well-described based on morphology and genetic sequence. ''Ectocarpus'' is a filamentous alga that can grow up to 30 cm. Cultured specimens in the laboratory tend to be fertile when they are 1–3 cm in length. ''Ectocarpus'' has a normal, branched appearance in unialgal cultures, but in axenic cultures it has a ball-shaped appearance suggesting that bacterial symbionts are required for the alga to attain normal morphology.


Distribution

''Ectocarpus'' can be found across the globe, in temperate shorelines growing as epiphytes on other flora (e.g. seagrass, other alga) or on rocky substrates (epilithic). While commonly attached to a substrate, thalli of ''Ectocarpus'' may also survive while floating. ''Ectocarpus'' are more commonly found as epiphytes on marine macroflora rather than epilithic. ''E. fasciculatus'' is known as an endophyte of ''Laminaria digitata'', but no study has documented how it bypasses the kelp's defense. ''E. crouaniorum'' are found in the intertidal zone while ''E. siliculosus and E. fasciculatus'' can be found in mid-intertidal and subtidal zones, respectively.


Ecology

''Ectocarpus'' thalli tend to shelter several marine invertebrates (e.g. crustaceans and nematodes) and some protists. Temperature affects the life cycle of some strains. A study of the life cycles of natural populations in NW France and SW Italy found marked isomorphy between generations in some populations and evidence of populations with modified, asexual life cycles.


Life History

In the laboratory, the life history is an isomorphic to slightly heteromorphic alternation of generations, but asexual strains also exist. ''Ectocarpus'' has a haploid-diploid life cycle with both sporophyte and gametophyte generations. It can complete its whole life cycle within 3 months in the laboratory. Diploid sporophytes give rise to haploid meiospores which will then produce a haploid gametophyte generation. These gametophytes are dioecious, producing either male or female gametes, which fuse to produce diploid zygotes, restarting the sporophyte stage. Parthenogenesis may also occur when a gamete does not find a gamete of the opposite sex, producing a parthenosporophyte. Deployment of the sporophyte developmental program requires two TALE homeodomain transcription factors, OUROBOROS and SAMSARA. If either of the genes encoding these two proteins is dysfunctional, the alga develops as a gametophyte.


Cultivation and Exploitation

A protocol has been established to culture ''Ectocarpus'' in the laboratory. ''Ectocarpus'' is able to grow in artificial seawater although the standard medium is Provasoli-enriched seawater (PES). Standard laboratory conditions are growth at 13 degrees Celsius under a 12h:12h light:dark cycle with irradiance at 20 μmol photons m−2 s−1.


Chemical Composition

Iodide originating from seawater can accumulate to high concentrations in several brown algae but high levels are not observed in ''Ectocarpus''. Genes predicted to encode enzymes involved in iodine metabolism have been identified in ''Ectocarpus'', including haloperoxidases, dehalogenases and haloalkane dehalogenases. These enzymes may be part of the defence mechanism of ''Ectocarpus'' against halogenated defenses of brown algal hosts when growing as an epiphyte.


Utilization and Management

''Ectocarpus'' is vulnerable to an array of pathogens and parasites and is also sensitive to abiotic stresses such as shifts in temperature, light and salinity. Major modifications to the ''Ectocarpus'' transcriptome have been observed following stress treatments.
