FDXR and infection: Host transcripts that were diminished in light infection included photosystem I assembly protein Ycf37 and ferredoxin–NADP+ reductase (FNR)—which were also diminished in dark (discussed below)—and translation-related genes including multiple tRNAs and ribosomal proteins, consistent with the significant changes in protein translation that must occur in the shift from host to phage protein synthesis.
