Different patterns of chlorotic to yellowish mottling, mosaic spots and deformation were observed in leaves of field grown figs. The causal virus was identified as Fig mosaic virus (FMV). Electron microscope observations of thin-sectioned tissues from symptomatic leaves or from purified preparations showed double membrane bodies (DMBs) characteristic for FMV particles, which belong to family of Bunyaviridae. FMV infection also caused increases in H2O2 and malondialdehyde (MDA) contents. These results suggest that FMV infection causes oxidative stress in fig leaves leading to the development of epidemiological symptoms.
