Importance of organism and transcriptomes | The 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, Schizochytrium aggregatum ATCC28209 was among the first described in detail, is thought to be cosmopolitan, and is probably the best studied. Schizochytrium aggregatum has specifically been shown to degrade cellulose (Bremer and Talbot 1995) and so may be particularly well-suited to growth on refractory material of terrestrial origin, and provide a conduit for this material into marine food webs. |
