Given that all these genes were expressed during a transcriptional study of M. pusilla UTEX LB991 infected by MpV-SP1 [58], similarly to the expression of transaldolase, glucose-6-phosphate dehydrogenase and 6-phospohgluconate dehydrogenase in cyanophages [59], these genes may influence the host’s metabolism during infection to boost viral replication. The gene discussed is G6PD; the disease is infection.
