Abstract

Although viruses can significantly reduce primary production-mediated carbon cycling, the effect of viral infection on the principal photosynthetic pigment that enables autotrophic production, chlorophyll a (chl a), remains unresolved. We compared the production of chl a transformation compounds in...
