Plate 2. Fruit aroma volatiles are both attractive to humans and indicators of ripeness (Goff, S.A. and Klee, H.J.
(2006) Plant volatile compounds: sensory cues for health and nutritional value? Science 311(5762), 815-819).
Plate 3. Expression of a -glucuronidase (GUS) reporter driven by the tomato SlCER6 promoter region. GUS

expression is driven by the wax biosynthesis SlCER6 promoter and shows gene expression in the exocarp (Ex) and
endocarp (En) tissues in a tomato fruit slice, indicating the presence of the inner epidermal cuticular layer
(Mintz-Oron, S., Mandel, T., Rogachev, I., Feldberg, L., Lotan, O., Yativ, M., Wang, Z., Jetter, R., Venger, I., Adato,
A. and Aharon, A. (2008) Gene expression and metabolism in tomato fruit surface tissues. Plant Physiology 147,
823-851).
Plate 4. Responses of tomato fruit with depleted cuticle to fungal infection. Tomato fruit were inoculated with Col-
letotrichum coccodes conidia. Photographs taken at 5 days post-inoculation show that the wild type (WT) had neg-
ligible fungal growth, whilst the slcyp86a69 mutant had developed a severe infection (Shi, J.X., Adato, A., Alkan,
N., He, Y., Lashbrooke, J., Matas, A.J., Meir, S., Malitsky, S., Isaacson, T., Prusky, D., Leshkowitz, D., Schreiber,
L., et al. (2013) The tomato SlSHINE3 transcription factor regulates fruit cuticle formation and epidermal patterning.
