18S rRNA
Importance of organism and transcriptomesCercozoans are frequently found in 18S rRNA clone library surveys of marine environments and are thus considered ubiquitous in marine environments. They likely consume bacteria including cyanobacteria as prey, and thus are involved in recycling of nutrients through the microbial loop. Their biology is not well studied and we could not find a genome project for this group. This isolate was obtained from the SIO pier (UCSD, La Jolla, CA), has been in culture for more than a year and grows on a single Synechococcus strain and contaminating bacteria as food. This group would be important for phylogenetic reasons as part of a poorly sampled superfamily and for ecological reasons. We would hope to compare its transcriptome during growth with and without Synechococcus and to other nanoflagellates growing with and without Synechococcus.
