In order to test the effect of the bacterial strains on the accumulation and spread of PVX and PVY in tomato plants, we studied the expression of the PVX CP and PVY PIPO viral genes at 7 and 14 days post-inoculation (dpi) and determined the presence of the viruses using DAS-ELISA 2 and 10 weeks after infection (Figure 2, Table S3). The gene discussed is CP; the disease is infection.
