Leaf phenotype and TYLCV DNA accumulation 21 days after TYLCV infection of the susceptible tomato lines JS-CT-9210. a The new merging leaves phenotype. CK is untreated tomato plants. TYLCV is tomato plants with TYLCV infection. b The TYLCV DNA accumulation in new emerging leaves measured by qPCR. Tomato α-tubulin (Solyc04g077020.2) was used as an internal reference. Error bars represented standard errors of three biological replicates, and asterisks indicate significant differences based on the Student’s t test (P < 0.05)
