Transcriptomic response of Alexandrium catenella to phosphorus changing

Phosphorus (P) is a key macronutrient limiting cell growth and bloom formation of marine dinoflagellates. Physiological responses to changing ambient P have been investigated in dinoflagellates; however, little is known about the molecular mechanisms behind these responses. Here, we compared the transcriptomes of a dinoflagellate Alexandrium catenella grown in inorganic P-replete, P-deficient, and inorganic- and organic P-resupplied conditions using RNA-Seq and characterized differentially expressed genes.
