Importance of organism and transcriptomesThe labyrinthulomycetes (including labyrinthulids, oblongichytrids, thraustochytrids, and aplanochytrids) are ubiquitous, diverse, and abundant marine protists (e.g. Collado Mercado et al. 2010 and references therein). They are thought to live mainly as saprobes, obtaining their nutrition from non-living particulate organic matter (POM) of algal, higher plant, or animal origin. Thus, while labyrinthulomycetes are not fungi in a taxonomic sense, they function as fungi in an ecological sense, likely playing important roles in the decomposition of marine POM. Among the labyrinthulomycetes, Aurantiochytrium limacinum ATCCMYA-1381 may be particularly well-suited to growth on refractory material of terrestrial origin and help to provide a conduit for this material into marine food webs.
