Importance of organism and transcriptomesDue to its relative large size (apical axis: 240-320 ?m; width: 28-32 ?m), O. sinensis represents an excellent model species for cellular studies of silicification and physiological processes in the diatoms. We have made the remarkable discovery that O. sinensis cells exhibit plasma membrane action potentials resembling the biophysical and pharmacological characteristics of the action potential found in excitable animal cells (Taylor 2009). Moreover, recent evidence indicates these action potentials may act via a novel mechanism to mediate pH homeostasis in O. sinensis and may be impacted by ocean acidification.Deep sequencing of O. sinensis transcriptome will not only contribute to better understand the complex diatoms phylogeny and evolutionary history but will also bring for the first time the sequence information necessary to complement the molecular and physiological studies currently undertaken on this model diatom species.
