Morphological changes caused by dimethyl disulfide (DMDS) in Sclerotinia minor Fluorescence micrograph of S. minor under (a) control and (b) treated conditions. Hyphae were stained with propidium iodide (PI) at a concentration of 10 µL/mL. (c) Scanning electron micrograph showing ultra-structures of S. minor hyphae in under control conditions. (d) Scanning electron micrograph showing ultrastructural changes in S. minor when mycelia were exposed to volatile DMDS. (e) Transmission electron micrograph showing the ultrastructure of S. minor hyphae under control conditions. (f) Transmission electron micrograph showing ultrastructural changes in S. minor when mycelia were exposed to volatile DMDS. VH = vegetative hyphae, R = rind, BH = broken hyphae, SH = swollen hyphae, C = cytoplasm, M = mitochondria, W = wall, E = extracellular matrix, L = electron dense line, ER = Endoplasmic reticulum, N = Nucleus, V = vacuole, CC = condensed cytoplasm, LC = lost cytoplasm, DW = deformed wall, SE = swollen extracellular matrix, DL = degenerated electron line, DGB = degenerated Golgi body, DN = distorted nucleus.
