AB  - Introduction - Fruit and their products, including fruit wines, represent a rich source of natural bioactive compounds. This study focusing on fruit wines (prepared from commercially grown fruits by Serbian producers) has included the investigation of their chemical composition and biological activity. Materials and methods - Black chokeberry, blueberry, raspberry, blackberry and cherry were used for wine production by innovative vinification procedure, with or without using sugar and enzymatic preparation glycosidase, respectively. Selected phenolics were identified and quantified by UPLC/MS-MS analysis, while Total Phenolic Content (TPC) was determined by the Folin-Ciocalteu method. In addition to this, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and FRAP (Ferric Reducing Ability of Plasma) methods were applied for the preliminary evaluation of anti-DPPH radical activity and redox potential respectively at in vitro conditions. Results and discussion - Among the fruit wines examined within this study, the blackberry one stood out for profound FRAP (115.23 mmol L-1 Fe2+), DPPH (1.11%) and TPC values (2,395 mg GAE L-1). On the other hand, the raspberry wine showed the lowest potential towards the aforementioned parameters. Using principal component analysis, these fruit wines were chemically differentiated, according to the predominant phenolic compounds. Conclusions - All fruit wine samples displayed a good antioxidant potential with the blackberry one being most potent. Such a finding is of particular importance for Serbia as one of the leading producers of this edible fruit both in Europe and rest of the world.

AB  - Elm yellows phytoplasmas (EY) belonging to the 16SrV-A subgroup were recently proposed as a new candidate species 'Candidatus Phytoplasma ulmi'. These pathogens infect elm trees, causing leaf yellowing and premature drying. In this study, 25 isolates originating from localities in northeast, east and southwest Serbia were characterized by means of RFLP analysis and DNA sequencing of four genomic loci: 16S rRNA, ribosomal protein rpl22-rps3, secY and map. In total, five different genotypes were identified based on collective sequencing of all four genes. Four of these genotypes showed significant nucleotide changes compared with the EY1T reference strain. Phylogeny based on parsimony analyses of ribosomal protein, secY and map genetic loci indicated a single monophyletic origin of EY1T and the new 'Ca. Phytoplasma ulmi' strains. Unlike phylogenetic clustering, DNA sequence comparison of EY1T and the novel strains revealed mutations in oligonucleotide signature sequences for all three genes (16S, rpl22-rps3 and secY) used for the characterization and assignment of 16SrV-A phytoplasmas to the 'Ca. Phytoplasma ulmi' species in the original description. Based on their high degree of genetic variability, the Serbian strains were assigned to four different subtypes of 'Ca. Phytoplasma ulmi' (EY-S1, EY-S2, EY-S3 and EY-S4). New diagnostic enzymes for practical use in 'Ca. Phytoplasma ulmi' identification are proposed for the 16S rRNA, ribosomal protein and secY genes. The implications of genetic variability within signature sequences for taxonomy and identification of 'Ca. Phytoplasma' species, as well as the importance of geographic variability and number of strains characterized for species description, are discussed.

AB  - Maize redness (MR), induced by stolbur phytoplasma ('Candidatus Phytoplasma solani', subgroup 16SrXII-A), is characterized by midrib, leaf, and stalk reddening and abnormal ear development. MR has been reported from Serbia, Romania, and Bulgaria for 50 years, and recent epiphytotics reduced yields by 40 to 90% in South Banat District, Serbia. Potential vectors including leafhoppers and planthoppers in the order Hemiptera, suborder Auchenorrhyncha, were surveyed in MR-affected and low-MR-incidence fields, and 33 different species were identified. Only Reptalus panzeri populations displayed characteristics of a major MR vector. More R. panzeri individuals were present in MR-affected versus low-MR fields, higher populations were observed in maize plots than in field border areas, and peak population levels preceded the appearance of MR in late July. Stolbur phytoplasma was detected in 17% of R. panzeri adults using nested polymerase chain reaction but not in any other insects tested. Higher populations of R. panzeri nymphs were found on maize, Johnsongrass (Sorghum halepense), and wheat (Triticum aestivum) roots. Stolbur phytoplasma was detected in roots of these three plant species, as well as in R. panzeri L-3 and L-5 nymphs. When stolbur phytoplasma-infected R. panzeri L-3 nymphs were introduced into insect-free mesh cages containing healthy maize and wheat plants, 89 and 7%, respectively, became infected. These results suggest that the MR disease cycle in South Banat involves mid-July transmission of stolbur phytoplasma to maize by infected adult R. panzeri. The adult R. panzeri lay eggs on infected maize roots, and nymphs living on these roots acquire the phytoplasma from infected maize. The nymphs overwinter on the roots of wheat planted into maize fields in the autumn, allowing emergence of phytoplasma-infected vectors the following July.
