Experiment purpose is to monitor the time-course of a large-scale infection of host cyanobacteria by phage under variable media conditions and obtain samples for proteomic and transcriptomic analysis.9 Hourly Timepoints: 0, 1, 2, 3, 4, 6, 8, 10, 14Sampling is to collect supernatant fractions to determine total dissolved phosphate and soluble reactive phosphate (TDP/SRP) for analysis of inorganic phosphate concentration and phosphate in dissolved organic material (DOM); and to collect pellets to isolate RNA for transcriptomics and proteins for proteomics.
