FIGURE 2

Scanning electron micrographs of adaxial surface of A. thaliana leaf. (A) Stomata of (a) control, (b) SNP, (c) AB alone, and (d) AB + SNP. S represents stomata and H represents hyphae of fungal pathogen. (Ba) Enlarged image of damaged stomata in AB alone and (b) enlarged image of normal stomata in AB + SNP treatment. (Ca,c) Image showing healthy mycelia and spore network on plant surface in AB alone. (b,d) Absence of mycelia network and damaged spores in AB + SNP. Cont, control; SNP, biogenic silver nanoparticles alone; AB, A. brassicicola-infected plants; AB + SNP, A. brassicicola-infected, treated with SNP.
