Analysis of expressed sequence tags from a naked foraminiferan Reticulomyxa filosa.

Foraminifers are a major component of modern marine ecosystems and one of the most important oceanic producers of calcium carbonate. They are a key phylogenetic group among amoeboid protists, but our knowledge of their genome is still mostly limited to a few conserved genes. Here, we report the first study of expressed genes by means of expressed sequence tag (EST) from the freshwater naked foraminiferan Reticulomyxa filosa.
