Project description:Cyanophage infection outcomes depend strongly on host physiological state, yet the transcriptional dynamics of the P-SSP7–Prochlorococcus MED4 interaction under different light regimes remain poorly understood. This dataset captures the time-resolved transcriptional response of Prochlorococcus MED4 following infection with cyanophage P-SSP7 under three light conditions: standard light, high light, and darkness.
