Abstract

Different syndromes of a putative viral origin are comprised under the name ofFig mosaic disease (FMD), an aetiologically ill-defined infectious disease of figtrees, reported from all fig-growing countries in the world. In fact, at least 10different viruses and three viroids have been detected to date in FMD-affectedtrees: five closterovirids (Fig leaf mottle-associated virus 1 and 2, Fig mildmottle-associated virus, Arkansas closterovirus 1 and 2); a Trichovirus (Figlatent virus 1) and several isometric, bacilliform or enveloped viruses (Figcriptic virus, Fig fleck-associated virus, Fig badnavirus 1, Fig mosaic virus). Ofthese, Fig mosaic virus (genus Emaravirus) is the one with the highestassociation with FMD. Fig badnavirus 1, whose DNA is integrated in the figgenome, may not induce a disease even when virus particles are expressed infig seedlings. The development of typical FMD symptoms in seedlings in whichFMV was transmitted by its vector (the eriophyid mite Aceria ficus) support theconclusion that FMV is indeed one, if not the major, agent of FMD. Virtuallynothing is known on the pathogenicity and epidemiology of the other fig infectingviruses. FMD has an extremely high incidence in nature andsymptomless trees are often only apparently healthy. Thus, any campaign forthe improvement of the fig industry should utilize sanitation techniques for theproduction of certified healthy stocks for propagation and trade.
