SlBIGPETAL1 and SlOVA6 time course gene expression comparison of TPMVd and MPVd-infected vs mock-inoculated tomato plants. (A) SlBIGPETAL1 and (B) SlOVA6 gene expression during three infection stages: 1, early infection; 2, middle infection and 3, late infection. Gene expression values are relative to mock-inoculated controls to which a value of 1 was assigned. The EF-1α elongation factor gene was used as an internal reference. Error bars indicate two times the value of the SD for the corresponding data set. Asterisks indicate statistical significance when analyzed using a paired t-test (p < 0.05). Where both treatments are statistically significant from mock-inoculated controls, one asterisk is placed above the bars.
