Relative levels of transcript-related RNAs of Cronartium ribicola totiviruses (CrTV1 to CrTV5) as measured by FPKM using RNA-seq data. a Relative RNA levels of each virus compared with three stages of the fungal life cycle (aeciospore, urediniospore, and in planta mycelium growth); b Relative RNA levels in each sample type compared with the five totiviruses in each of three sample types. Bars show average RNA levels of each virus with standard error of the mean (SEM). Different letters on the tops of the bars indicate significant differences (t-test, P < 0.05) between the samples or the viruses from the same fungal sample using t-test
