Importance of organism and transcriptomesPteridomonas species consume bacteria including cyanobacteria and small phytoplankton as prey, and thus are involved in recycling of nutrients through the microbial loop. They have been important model organisms for studying grazer-prey dynamics. Theri 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 several years and grows on a single Synechococcus strain and contaminating bacteria as food. It's 18S rRNA sequence is 96% identical to Pteridomonas danica. This species is important for phylogenetic reasons as part of a poorly sampled group the Dictyochophyceae 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 to better understand the mechanisms of Synechococcus recognition and digestion.
