Botrytis cinerea infection
The fungus was cultivated in potato dextrose agar plates, supplemented with freeze-dried tomato leaves. Three weeks later, B. cinereaspores were collected from plates in 0.5X potato dextrose broth as previously described (San Martin et al., 2020). Leaf inoculation was performed in detached leaves using two 6 µL drops containing a conidia concentration of 5 x 106 spores/mL per leaflet. Leaves were maintained in hermetically sealed boxes with 100% of humidity at 21ºC in darkness. Necrotic lesions were evaluated after 5 days.
