Dynamics of viral infection of E. huxleyi CCMP1516 by EhV201. a Cell abundance and b viral abundance of infected (triangles/dashed line) and uninfected (circles/solid line) cultures are a mean of n = 2 (±se) from one representative viral infection experiment. c Percent dead cells assessed by SYTOX Green, d intracellular ROS assessed by CM-H₂DCFDA, and e intracellular NO assessed by DAF-FM DA. Values represent the mean of at least n = 4 (±se) across at least 3 distinct infection experiments. Statistically significant differences between infected and control cultures were determined using unpaired Student’s t-test (*p < 0.05). f Histogram overlay of DAF-FM DA fluorescence values of one representative infected culture at 1, 24, and 48 hpi
