Characterization of a filamentous virus from Bermuda grass and its molecular, serological and biological comparison with Spartina mottle virus.

Bermuda grass with mosaic symptoms have been found in many parts of Iran. No serological correlation was observed between two isolates of this filamentous virus and any of the members of the family Potyviridae that were tested. Aphid transmission was demonstrated at low efficiency for isolates of this virus, whereas no transmission through seed was observed.

Virus diseases in the tobacco fields of Guilan and Western Azerbaijan provinces of Iran.

Tobacco (Nicotiana tabacum L.) is one of the important industrial plants in Iran. Viruses as an important group of plant pathogens cause many losses on the quality and quantity of tobacco crop.

Nodule infection by bean yellow mosaic virus in Vicia faba and molecular characterization of it.

Root nodules infection of different faba bean (Vicia faba L.) cultivars by bean yellow mosaic virus (BYMV) and the effect of the disease on the specific activity of the nodule are reported. The disease reduced the fresh weights of tops, roots, root nodules and induced premature nodule decay and/or nodule drop.

Carnation mottle virus, an important viral agent infecting carnation cut-flower crops in Mahallat of Iran.

One of the most important cut-flower crops grown worldwide on commercial scale is Carnation (Dianthus caryophyllus L.). It's the main production of Mahallat where is one of the most important ornamental plants production centers of Iran.

Occurrence and distribution of Potato virus Y strain N (PVY(N)) on celery in Iran.

Celery (Apium graveolens) is an important crop grown in many countries. Different types of diseases present a major constraint to Celery production and can lead to significant reductions in yield Potato Virus Y, the type member of the genus Potyvirus(family Potyviridae) is one of the causal agents of viral diseases in crops. In the present study, PVY occurring in celery fields was determined as the causal agent of mosaic disease of celery (Apium graveolens).
