Virus diseases of Apiaceae

The Apiaceae are a large plant family consisting of approximately 250 genera and over 3,000 species grown worldwide. Its representative vegetables are carrot, parsley, parsnip and celery, as well as some wellknown spice plants such as fennel, anise, caraway, dill, and coriander. Their production is imperiled by numerous pathogens, among which viruses are of great importance. Globally more than 30 viruses are known to affect carrot and other plant species belonging to family Apiaceae. The principal viruses are: Celery mosaic virus (CeMV), Parsnip yellow fleck virus, (PYFV), Carrot red leaf virus (CtRLV) and Carrot mottle virus (CMoV). In Serbia, three viruses are present on carrot and celery: CeMV, Cucumber mosaic virus (CMV) and Tomato spotted wilt tospovirus (TSWV). The economic importance of viruses infecting umbelliferous has long been recognised due to the foliar symptoms and viral dieback of seedlings. These viruses affect carrot crops only sporadically, but when they do occur they can be devastating. Other umbelliferous viruses are known to occur worlwide, however, their effects are not clear.
