Normalized quantitative real-time one-step reverse transcription PCR method to assess PEMV1 and 2 replication in pea plants with two inoculum conditions. Compared two different housekeeping genes for normalization of viral accumulation data. Accumulation of both viral RNAs was similar whether actin or β-tubulin mRNAs were used as reference transcripts. PEMV1 replication dynamics were changed by inoculum concentration when compared to PEMV2.
