Supplementary Information from ‘Sneezing’ plants: pathogen transport via jumping-droplet condensation We show that condensation growing on wheat leaves infected with <i>P. triticina</i> is capable of spontaneously launching urediniospores off the plant. This surprising liberation mechanism is enabled by the superhydrophobicity of wheat leaves, which promotes a jumping-droplet mode of condensation powered by the surface energy released from coalescence events. We found that urediniospores often adhere to the self-propelled condensate, resulting in liberation rates approximately 10 cm<sup>−2</sup> h<sup>−1</sup> for leaves infected with rust. Urediniospores were catapulted up to 5 mm from the leaf’s surface, a distance sufficient to clear the laminar boundary layer for subsequent dispersal even in gentle winds. wheat leaf;superhydrophobic;jumping-droplet condensation;spores;liberation;dispersal 2019-06-01
