Fig. 4: Polydimethylsiloxane (PDMS) artificial leaf surfaces of the abaxial side of Zantedeschia aethiopica (ZA) and the hybrid “Captain Romance” (CR) following application of Pectobacterium brasiliense (Pb).

In total, 10 µl of bacterial suspension (108 CFU/ml, OD600 = 0.1) were applied onto the surface of the replicas. A PDMS replica of ZA abaxial leaf surface. B–D ZA artificial surface following Pb application at a resolution of ×400, ×2000, and ×7000. E PDMS replica of CR as above. F–H Higher-resolution images of CR following bacterial application as above
