Fig. 2Â From: Nano-selenium enhances melon resistance to Podosphaera xanthii by enhancing the antioxidant capacity and promoting alterations in the polyamine, phenylpropanoid and hormone signaling pathwaysAnatomical structural characteristics of leaf mesophyll cells infected with powdery mildew at 1 and 10 dpi in susceptible and resistance cultivars with or without Nano-Se treatment. The panels (a1, a2, b1, b2), (c1, c2, d1, d2) and (e1, e2, f1, f2), (g1, g2, h1, h2) represent the paraffin section images of powdery mildew susceptible (JSG, ZZX) and resistant cultivars (HMC, JX) at 1, 10 dpi in the control and Nano-Se treatment group, respectively.
