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. It has recently become apparent that the most abundant labyrinthulomycetes in habitats ranging from coastal temperate sediments to the equatorial open ocean water column belong to the genus Aplanochytrium (Collado Mercado et al. 2010, Damare and Raghukumar 2010 and references therein).
