Abstract Background Signal-Mediated Amplification of RNA Technology SMART is an isothermal nucleic acid amplification technology developed for the detection of specific target sequences either RNA for expression or DNA. Cyanophages are viruses that infect cyanobacteria. Marine cyanophages are ubiquitous in the surface layers of the ocean where they infect members of the globally important genus Synechococcus. Results Here we report that the SMART assay allowed us to differentiate between infected and non-infected host cultures. Expression of the cyanophage strain S-PM2 portal vertex gene g20 was detected from infected host Synechococcus sp. WH7803 cells. Using the SMART assay we demonstrated that g20 mRNA peaked 240 - 360 minutes post-infection allowing us to characterise .
