  Host plant susceptibility genes, which facilitate pathogen growth during plant infection, are attractive targets for disease-resistance breeding. To explore candidate susceptibility genes in tomatoes during Botrytis cinerea infection, the fungal infection-responsive SWEET genes were screened for out of all 31 tomato SlSWEET genes. The expression of only one gene, SlSWEET15, was induced by B. cinerea at the pre-necrotic stage (16 h post inoculation), whereas most of the other SWEET genes were downregulated. The expression of the SlSWEET15 transiently increased by 16 h post inoculation, then reduced to basal levels by 24 h post inoculation. We measured the glucose and sucrose contents of fluid of infected cotyledons at the pre-necrotic stage (20 h post inoculation). The sugar contents of the apoplasmic fluids were significantly higher in the i.. View More»
