Cellular caspase activation in natural E. huxleyi populations of bag 3 during EhV1 infection in phase 3 of bloom demise as determined by CaspACE (FITC-VAD-FMK) staining and flow cytometry analysis. Plots of chlorophyll fluorescence and FITC fluorescence distribution for unstained and CaspACE-stained E. huxleyi cell populations are given for each designated sampling day (5,000 cells counted). Quadrant plots Q1-1 and Q2-1 correspond to negatively and positively stained E. huxleyi cells, respectively. The percentage of positively stained cells (Q2-1 quadrant) is provided in parentheses. The mean FITC fluorescence value is also indicated for negatively and positively stained CaspACE-stained cells.
