Symptoms of fruits in PSTVd-tolerant ‘Tiny-Tim’ tomatoes. (A) ‘Tiny-Tim’ tomatoes did not clearly show morphological symptoms in stems and leaves at 6 weeks post-inoculation. (B) The fruits from PSTVd-infected plants became significantly smaller in size and lost their surface luster; in particular, the fruits from PSTVd-AS1-infected plants did not form any seeds. (C) The average weight of fruits derived from PSTVd-infected plants was low compared with that from mock-inoculated, but there was no difference in total number of fruits. The significant difference in the fruit weight was confirmed by the Tukey–Kramer test.
