108 sample Collected from the fields of farmers in the areas of apple cultivation in the south of Syria during the years 1998-2007, and the most important symptoms associated with infection were recorded, results of the biometric tests (mechanical inoculation on indicator plant) and examination by electron microscope and serological tests (ELISA) using antisera of Apple mosaic virus, Apple chlorotic leaf spot virus, Tomato ring spot virus , Tomato spotted wilt virus, Tobacco ring spot virus , Tomato black ring virus and Arabis mosaic virus to the spread of a virus infection of Apple chlorotic leaf spot virus (ACLSV) by 24%, Apple mosaic virus (ApMV) by 26.9% and to register cases Tomato ring spot virus (TomRSV) by 13% and Tobacco ring spot virus (TRSV) by %14.8, Tomato black ring virus (TBRV) rate of % 12.03 and Arabis mosaic virus (ArMV) 2.43% for the first time on apples in Syria, and the likelihood of several viral and viroid diseases, that we need to reassess the health situation in view of the importance of maintaining the cultivation of apples and recommended program documentation for the production of propagation of disease-free, with proposal to use molecular methods to detect and identify viral diseases causes and strains prevalent in Syria.

Virusi jabuke, kruške ili dunje relativno su slabo poznati stručnjacima i voćarima. Najvažnijim virusima koji se javljaju na jezgričavim voćnim vrstama smatraju se virus mozaika jabuke (Apple mosaic virus, ApMV), virus klorotične pjegavosti lista jabuke (Apple chlorotic leaf spot virus, ACLSV), virus brazdavosti debla jabuke (Apple stem grooving virus, ASGV) i virus jamičavosti debla jabuke (Apple stem pitting virus,ASPV). U radu je ukratko opisana njihova važnost, biologija i regulativni status, kao i osnovne mjere zaštite.

Rna Binding Domain

The RNA-binding properties of the cell-to-cell movement protein (MP) of Apple chlorotic leaf spot virus were analysed. MP was expressed in Escherichia coli and was used in UV-crosslinking analysis, using a digoxigenin–UTP-labelled RNA probe and gel-retardation analysis. The analyses demonstrated that MP bound cooperatively to single-stranded RNA (ssRNA). When analysed for NaCl dependence of the RNA-binding activity, the majority of the MP could bind ssRNA even in binding buffer with 1 M NaCl. Furthermore, competition binding experiments showed that the MP bound preferentially to ssRNA and single-stranded DNA without sequence specificity. MP deletion mutants were used to identify the RNA-binding domain by UV-crosslinking analysis. Amino acid residues 82–126 and 127–287 potentially contain two independently active, single-stranded nucleic acid-binding domains.
